Sky loungers by Holztec-Leitner © Yaskawa
Success came literally overnight for Holztec-Leitner based in Schliersee in Upper Bavaria: no sooner had company boss Franz Leitner placed his self-designed, hand-made swing and relaxation loungers made of larch and spruce in an online shop, the first orders started to come in. And numbers have been growing ever since: subject to copyrighted design throughout Europe, the Himmelsliegen (“sky loungers”) are no longer just at home on the banks of Lake Schliersee but on numerous terraces and in gardens and parks as far afield as Mallorca and Italy.
After the initial surprise, Holztec-Leitner quickly realised that a partner was needed to supply the high quantities required on an ongoing basis. The partner was to take over production of the high-quality pivot mounts made of solid metal: the sky loungers are not only attractive and comfortable, they also rotate by 360°.
In his search for a suitable specialist, Franz Leitner first tried his luck on his own doorstep in Schliersee – and found just what he was looking for at Stöckl Maschinen und Gerätebau GmbH. “That’s how it all started,” says Kamil Kowalski, one of two Stöckl managing directors, looking back on the beginnings of this successful collaboration.
Established in 1989, the company specialises in the manufacture of welded and assembly components made of steel, stainless steel and aluminium. These are used in traditional machine and device construction, but also in railcars and special vehicles, for example.
Before the enquiry came in from Holztec-Leitner, however, the sophisticated designs were usually only produced in small batches and predominantly by hand. At the end of 2020, Kamil Kowalski and his colleague Christian Strobl took on the challenge of putting together several hundred pivot mounts per year by means of welding – or rather: automated welding. What was needed was a compact robotic welding system that was both quick to commission and easy to operate.
Yaskawa’s Weld4Me cobot welding cell proved to be the ideal solution: it is a compact unit that combines the advantages of a collaborative robot and a simple user interface with professional welding functions. With its decades of experience, the manufacturer is thus able to provide small and medium-sized companies that have previously welded by hand with an optimum way of moving into automated robot welding.
The cell went into operation at Stöckl Maschinen und Gerätebau at the beginning of 2022. As an optional extra, it is equipped with magnetic holders instead of the usual clamping devices. “The cut-to-size profiles are simply inserted and fixed in place magnetically at the touch of a button,” says Kamil Kowalski. “This ensures the components are always in exactly the same place.”
Specifically, the Weld4Me cell consists of a Cobot HC10DT IP67, a YRC1000 controller with functional safety unit (FSU), a welding table, a glare shield and other optional features, as well as extensive functions for MIG/MAG welding. The collaborative robot is designed to meet the requirements of protection class IP67, so it is resilient to welding splashes during the production process. The comprehensive welding package that comes with it consisting of power source, cable package, wire feeder and welding torch is available from numerous well-known manufacturers. Yaskawa now also offers this compact cobot welding solution as a CE-capable Weld4Me CE complete cell.
The complete cell takes into account the requirements of human-robot collaboration in terms of risk assessment and ensures safe welding operation thanks to the safety set-up. This means that the robot can be set up directly without a fence using integrated torque sensors. As soon as the curtains are closed, it operates in industrial mode.
So even more complex welding tasks can be programmed on the HC10DT IP67 in two alternative ways: in conventional fashion using a programming handset (Teachbox) or by manually guiding the cobot arm (Direct-Teach). Stöckl Maschinen und Gerätebau currently still favours programming via Teachbox, but Managing Director Kamil Kowalski appreciates the Cobot-specific option of hand-guided programming, too. This is because it is easy to move the collaborative robot into new welding positions by manually guiding it, and these positions can be programmed on the simplified “Welding Wizard” user interface. Practical control buttons on the flange also make it easier to programme the welding job. Once the programme has been created, the robot path can be checked again on a dry run before the robot gets to work on the welding. There is no need to learn complex programming environments, so that leaves more time for the actual welding process. This solution is particularly suitable for small batch sizes and a wide variety of products, since it minimises the effort required to change over to a new part.
The new Weld4Me cobot welding cell has been up and running successfully at Stöckl Maschinen und Gerätebau since the beginning of 2022, with a current annual throughput of around 1,000 pivot mounts. “All in all, our entry into robotics has been a success,” says Managing Director Kamil Kowalski, who wouldn’t want to do without the robot: “The Yaskawa welding cobot will remain our only robot for the time being – but it’ll be taking on even more tasks in the future.”
In 2021 three HC10 robots arrived at Fagerhult as an unexpected opportunity to make the most of. Fagerhult was familiar with robotic automation, including five conventional Motoman robots already in operation, but had limited experience of any type of collaborative robots. Aiming to create a productive solution on their own their challenge was: to break down products into suitable assembly tasks for the robots and test, evaluate and create a productive application without external help.
With initial training and support from Yaskawa, Fagerhult’s automation department were able to do all the testing, evaluation, and development of the final application on their own. The robotic assembly includes:
RFID tags are used to keep track on the components to be assembled for each product. Using safety scanners, the robots can alternate between their industrial mode in full speed and a safe collaborative mode.
This inhouse automation approach has increased Fagerhult’s desire to add more robotic automation projects in the future.

The solution to this problem was the installation of the T-Skin on the FANUC M-20iD/35, a compact 6-axis robot with a payload capacity of 35 kg. This collaborative robot (cobot) was chosen due to its ability to work in confined spaces alongside human workers, addressing the spatial constraints that ruled out other automation solutions. Additionally, the T-Skin technology ensured safety without the need for extensive fencing, making it a practical and efficient choice for the task.
The implementation of the cobot was remarkably swift, taking only half a day to complete. This rapid deployment minimized disruption to ongoing operations and allowed Carrier Transicold to quickly benefit from the new technology.
The introduction of the cobot brought significant benefits to the Singapore factory. Over 8,000 annualized hours of productivity were gained, showcasing the efficiency and reliability of the robotic solution. The cobot assisted in tasks such as attaching access doors on refrigeration units, freeing up human workers to focus on more complex and higher-value operations.
In addition to the immediate productivity gains, Carrier Transicold also saw broader benefits from their automation and digital transformation initiatives. The factory achieved an incremental 3% automation of manufacturing standard hours, enhancing overall efficiency. The adoption of radio frequency identification (RFID) improved inventory tracking, reducing human error and boosting operational efficiency. Digital First-Pass-Yield processes streamlined quality testing, providing real-time feedback that enhanced factory performance and quality control. Moreover, production capacity expanded, resulting in a 10% increase in output.
Carrier Transicold's commitment to innovation and sustainability was evident through these advancements. The cobots exemplified the company's strategy of integrating smart machines with human labor to create more customized, sustainable, and resilient operations. As part of a five-year automation roadmap initiated in 2019, these efforts have laid a solid foundation for ongoing improvements.
In conclusion, Carrier Transicold's innovative use of collaborative robots at their Singapore factory has not only solved immediate operational challenges but also significantly enhanced productivity and efficiency. The success of this initiative underscores the potential of Industry 5.0, where humans and robots work side by side to achieve superior outcomes.
Sano, founded in 1960, is a leading company in the manufacturing of various household and cleaning products with over 500 different products, including detergents, insecticides, laundry products, and cleaning solutions.
With a robust workforce of 1,700 dedicated employees, Sano remains committed to upholding its status as an industry leader, and consistently seeks out innovative approaches to augment operational efficiency and productivity.
As part of their ongoing efforts to improve production processes, Sano sought to optimize their palletizing operations. Traditionally, palletizing had been carried out by manual labor, but the company was increasingly aware of the limitations. The shortage of available workers, along with the continuous need for a non-stop production line, meant that automation was the logical step forward.
“Four years ago, we heard about collaborative applications, so we decided to explore their integration into our production lines” said Guy Sameach, Plant Engineer at Sano. “Especially for the tasks not requiring high-speed execution as palletizing, this solution seemed to be a perfect for automation with a collaborative solution” explained Guy.
The challenge for SANO was to find a solution that could work safely with workers while could minimize the footprint, as their factory already housed larger industrial robots that required dedicated fencing and safety systems and large space for it.
Before deciding for collaborative palletizing, the process was manually done.
“In the last years we are facing more and more problems to find operators. There is a lack of workforce that sometimes makes it impossible to cover the open positions we need. That was one the reason we also decided to install the palletizing stations” explains Guy.
As production demands increased, SANO struggled with the growing issue of space constraints in their factory. Palletizing products up to 2 meters high required an efficient solution that would optimize the use of their limited available space.
In their pursuit of the ideal palletizing solution, Sano evaluated different alternatives.
“We were positively impressed by the expertise OnRobot’s partner, ASSATEC, offered us” said Guy. “They perfectly understood our needs and they proposed us a simple solution, easy to integrate and fulfilling all our technical needs.”
ASSATEC's proposal was to install 2 palletizing stations formed by Collaborative Fanuc CRX mounted on an OnRobot Lift100 and equipped with a fully electrical 2FGP20 OnRobot gripper. “SANO needed a versatile gripper to palletize and place interlayers. The main challenge was to build 1.9 m. high pallets, but this was easily solved with OnRobot Lift100” explained Or Levy, ASSATEC Manager. The solution implemented worked smoothly, enabling easy pallet handling. With 11 different box types to be palletized, the 2FGP20 gripper from OnRobot proved to be a perfect solution. The 2FGP20's high total stroke (260 mm) allowed it to handle all box variations efficiently, making it a 100% electric, cost-effective choice.
Sano was particularly impressed with the small footprint of the solution. OnRobot Lift100 was efficient and compact with a quick integration process which further impressed Sano. “It took approximately 1 week to fully integrate the first palletizing solution into the line, and the second stations was even faster,” said Guy Sameach. The remarkable ROI of less than 1.5 years further solidified their decision.
Alexander Fahringer, Technical Development and Test Engineer at Gronbach, is con-vinced that cobots will have a firm place in quality management and other areas in the future. © KUKA
Previously reserved for coffee machines that were designed for the food service industry, Gronbach's development engineers relied on the support of the LBR iisy cobot from KUKA.
The Gronbach Group was originally founded in 1964 as a hinge manufacturing company. After rapid development, Gronbach currently manages five production sites in Europe, a sales office in the U.S. and around 1,200 staff members. As an original equipment manufacturer (OEM), they specialize in the development and production of technical assemblies and complex products. These products are delivered internationally to more than 500 customers that vary from start-up organizations to large corporations. They work predominantly in the household appliances industry with coffee machines, cooktops, steamers and numerous other devices. Gastronomy, medical and automotive industries are also represented among its customers.
For Gronbach, quality is their top priority. At the production and research and development (R&D) site in Niederndorf, Austria an in-house team is devoted to research and customer-specific development of product assembly. Everything comes together in terms of mechanics, electronics, software and several other technical categories. The commonality between these products is their high-quality standard for technology, sustainability and energy efficiency. For the quality control of this exacting coffee grinder, engineers relied on the support of the LBR iisy cobot from KUKA during testing.
As a premium OEM, Gronbach has broad manufacturing expertise with comprehensive knowledge in the R&D field. Built from hundreds of personalized and successfully completed projects, their broad knowledge has now resulted in its own brand name - LIGRE. LIGRE is actively entering the market as a manufacturer of high-end coffee machines. One of the first products to be launched on the market is the LIGRE siji coffee grinder alongside a LIGRE espresso machine.
The LIGRE siji coffee grinder provides a completely new feature for a coffee grinder in the consumer goods industry with the ability to preset the amount of coffee to be ground to the exact gram. To ensure that the proverbial high-quality standard is not an empty promise, the R&D experts at Gronbach decided to subject this new quality control development through a series of tests. The assumption was that the coffee grinder would grind or process around 500 kg of coffee over a service life of around 10 years. Determining the long-term correct weighing results under different operating conditions for half a metric ton of coffee required radical acceleration and extremely precise repeatability. The results of these tests had to be reliable so the findings could be incorporated in future developments.
The R&D experts at Gronbach all agreed that an automated robot solution was the only way to achieve cost-effective quality control during product testing. The leap to KUKA was a short one since multiple industrial robots are already in use at the company's site in Niederndorf. KUKA’s LBR iisy cobot was a perfect robotic solution.
With a maximum load of 3 kg, the agile cobot's full capacity was not used in this case. “It's good to know that there is more scope for other possible applications and processes,” says Alexander Fahringer, Technical Development and Test Engineer of Gronbach. Fahringer is positive that this project demonstrates that collaborative robots have a firm place in development departments, especially with quality control. KUKA also offers the LBR iisy cobots with maximum loads of up to 15 kg and a reach of 760 to 1,300 mm for projects that need a higher load.
The quality control test was scheduled over a two-month period during which the LBR iisy cobot would carry out 55,000 coffee grinding and weighing processes. Each process was carried out in six individual steps: taring the portafilter on the precision scale, gripping the portafilter and moving it to the coffee grinder, uncoupling the portafilter and waiting for the grinding process to end, picking up the filled portafilter and moving it to the scale, uncoupling and saving the scale value in the database, then picking up the portafilter, emptying it and placing it on the scale again.
One of the many benefits of the LBR iisy cobot is its simple programming through human-robot collaboration thanks to the Teach button. “You can guide the cobot manually and thus teach it the desired movements and waiting times very easily with the press of a button,” says Michael Reindl, Account Manager at KUKA. Thanks to its intuitive handling, the LBR iisy cobot offers flexible application options and can be commissioned and operated quickly and reliably by automation experts and robotics beginners alike. The robot meets all of the safety requirements for collaborative operation while being easy to use.
“The small LBR iisy cobot in particular is the variant with a load of up to three kilograms. In addition to the larger models, they are designed to take care of rather simple, monotonous and repetitive handling tasks in the immediate vicinity of other employees,” Reindl says describing the typical applications for a cobot. The 11- and 15-kg variants are even dust and splash-proof (protection class IP 54). The simple operation and high degree of flexibility distinguish the cobots from conventional industrial robots.
The cobot also eases the burden of employees being overworked which can become harmful to their health. Along with quality control, it offers added value thanks to precision, repeatability and easy handling. Each individual grinding and weighing process was carried out and logged in continuous operation with absolute reliability so that variances could be detected quickly. Processing the 55,000 test grinds is hardly worth mentioning for the cobot due to its longevity. “It's only just properly worn in,” Reindl says humorously, alluding to the several million cycles that the KUKA robots set as a standard in their performance. After gathering the results from the test, only positive outcomes were discovered. “The grinder worked so well that it indicated practically no wear and tear after simulated use for ten years, so it could last for significantly longer,” says Fahringer.
It is clear to the R&D team that this will not be the last time the LBR iisy cobot is used at Gronbach. “As automation engineers, we are already thinking about how the cobot will assist us in enhancing quality control and refining processes,” says Fahringer. One of the top contributing factors for this was the excellent collaboration with KUKA. The robotics experts deliberately make it easy for those who are interested in getting started.
“We are happy to provide customers with handy collaborative robots like the LBR iisy cobot to try out and test in their operation,” says Reindl. For anyone curious to test it out, the process is rather simple - the compact robot fits in any trunk.
The Electrolux Group is represented in more than 120 countries and sells more than 60 million products per year. The global leader in the sale of household appliances began operations in Brazil in 1926 and currently has four manufacturing plants across the country, two of which have been operating in Curitiba since 1996.
As part of a major investment and modernization program across all its sites in Brazil, Electrolux Group approached ABB in 2018 to find a way to automate the gas leak detection process on its refrigerator production line in Curitiba. The manufacturer wanted to eliminate repetitive manual operations to increase productivity and optimize the quality of its end products, as well as improving health and safety. Working together, ABB and Electrolux developed a solution to automate 100 percent of the operations involved in detecting gas leaks.
The installation of a YuMi cobot made it possible to replace manual verification, improving both the gas detection accuracy and the safety of employees. Freed from the strain of carrying out repetitive detection procedures, operators were redeployed to safer roles where they could add more value.
Collaborative robots can work safely alongside human operators without the need for traditional barriers, so they are especially useful in applications that need a lot of flexibility or where space is tight.
"The YuMi model proved to be the best solution for the application we were looking to automate in this line of refrigerators. It brought more security to our employees and increased the quality of tests. After that, we installed five more robots on the refrigerator production line, which significantly improved our productivity,” said Emerson Dlugosz, Manufacturing Engineering Manager at the Curitiba plant.
The success of the gas leak detection project prompted Electrolux and ABB to look for other opportunities, and soon the attention turned to an existing electrical test station that was not delivering the expected benefits.
The previous testing solution included a robot from a competing brand that kept interrupting production with unexpected stoppages. The ABB team proposed replacing the underperforming robot with a GoFa cobot, which belongs to an expanding family of collaborative robots developed by ABB to offer greater reach and higher payload capacity. Unlike the previous solution, the GoFa has since performed with 100 percent reliability.
“With the acquisition of the GoFa we had an eight percent gain in the effectiveness of tests and a reduction in unexpected stops in the multi-door refrigerator production line,” said Electrolux maintenance technician Ariel Alves, who was responsible for deploying the GoFa cobot and getting it up and running.
Introducing the GoFa is easy thanks to ABB’s Wizard Easy Programming tool, which is a graphical programming tool that enables even those with little previous experience of robots to program collaborative and industrial robots quickly, easily, and efficiently. This allowed the team at Electrolux to program the GoFa and get it up and running with only minimum telephone support from ABB. “ABB’s programming tools make it easy to use robotics in a simplified way in automated lines,” confirmed Alves.
The benefits delivered by the collaborative robots at Electrolux’s Brazil plants has led to an interest in seeing how their performance can be replicated at the company’s other production plants around the world.
“Thanks to our partnership with ABB, our production line now includes reliable, safe and easy-to-program robotic testing,” said Alves. “We can use internal operators to develop applications and our goal is to disseminate this knowledge so that the same methodology applied in these projects can be used to roll out robotic cells to meet different needs in our factories worldwide.”

Polar added OMRON’s LD 60/90 Mobile Robots to the expand their workforce. Finding skilled workers in an industry problem at the moment, and the solution enables Polar employees to utilize their skills and keep the tools running, and not worry about the transport of the product. The LD is a self-navigating Autonomous Mobile Robot (AMR) designed for dynamically moving material in challenging environments. It is capable of maneuvering through confined passageways and dynamic areas in the presence of humans.
Before starting the project, Polar mapped out their current processes, for example how long how long the materials were travelling within the factory. This was over 40 miles throughout the life cycle of the product! Polar carried out detailed simulation and mapping exercises in collaboration with OMRON. They analyzed the entire facility and evaluated the speed at which products could be transported throughout the production line. The results provided valuable insights into the feasibility and benefits of integrating OMRON's robotics solution, thereby justifying the investment.
Despite initial concerns regarding operator acceptance of the robotics technology, Polar’s operators quickly realized the advantages it brought to their work. The robots simplified their tasks, allowing them to focus on critical activities such as keeping the equipment running, while the robots ensure uninterrupted and timely material flow.
The implementation of the solution involved deploying a fleet of seven robots that efficiently transported materials from the main work-in-progress (WIP) storage area to various points within fabrication. OMRON's robots autonomously handle the transportation of materials over long distances, significantly reducing the need for manual intervention and improving overall efficiency in Polar’s manufacturing process.
Throughout the setup phase, OMRON played a pivotal role in supporting Polar. OMRON's team of engineers provided quick assistance whenever challenges arose. The availability and expertise of OMRON ensured the successful implementation and continuous improvement of the project.
Darren Desmarais, Industrial Engineer at Polar, highlights the transformative impact of OMRON's robotics solution, stating, "Having these robots available to move work-in-progress (WIP) quicker, easier, without relying on operators to move from the equipment they're working on. The biggest advantage I've seen is that we've been able to have the robots maneuver more like a person does."
The initial reluctance from operators and engineers to embrace the robots has evolved into high acceptance and appreciation. The seamless integration of OMRON's robotics solution has resulted in operators relishing their interactions with the robots and appreciating the timely delivery of lots to their respective tools. By eliminating the need for thousands of miles of walking within the facility each year, valuable time is saved for the operators, enhancing productivity and efficiency.
Thanks to OMRON's mobile robotics solution, Polar has successfully achieved its objectives of enhancing productivity, optimizing workflows, and creating a more streamlined and efficient semiconductor manufacturing process.
Masterpiece of 3D perception: KUKA, Roboception and QRS automate the production line at Danfoss © KUKA
At Danfoss, a Danish manufacturer of mobile hydraulics as well as electronic and electrical components, KUKA, QRS and Roboception are keeping the action mov-ing. Multiple robotic systems with 3D sensors reliably and precisely recognize and move over 100 different components. The three partners solved the numer-ous challenges together – with their valuable expertise and tireless commitment.
The camera performance of the new robotic cells with artificial eyes at Danfoss is definitely a contender for the “Masterpiece of 3D perception” award. This is because the system recognizes more than 100 different components in the production facility. It ensures that the KUKA robots in the cells of the Danish mobile hydraulics manufacturer efficiently and fully automatically load and unload machines in the production process.
With their new automation investment, the Scandinavians are precisely in tune with the Danish zeitgeist. This is because the northern Europeans already rank 6th in the world in terms of robot density in the manufacturing sector. It comes as no surprise that KUKA actively supported the project with its expertise. After all, the automation specialist supplies most of the robots in Denmark.
In the new production line at Danfoss, a total of six KUKA robots take over work steps that were previously performed manually. They move components weighing between 5 and 20 kilograms each. Automating this process reduces the physically demanding work for the team, allowing employees to take on more value-added tasks.
The robotic cells thus move up to 100 different components without manual intervention. “That was the major challenge in this project,” explains Olav K. Sjørslev, Sales Manager at integration partner QRS. “The requirement for the robotic cells at Danfoss was fully automatic feeding of the components – a task that can only be solved with a camera system, given the large number of variations.”
The alternative, namely feeding the blanks meticulously ordered and aligned, was simply not economically feasible. Instead, the components arrive at the first robot station in standard roll boxes, sorted by box, but with the boxes stacked on top of each other more or less indiscriminately, and with the layers of components separated by paper sheets.
“Our experience with camera systems in the past was not particularly good,” recalls Sjørslev. “We looked into various systems over the past decade, but did not find a single 3D vision solution that met our needs.” What works at a trade fair or in a manufacturer’s demonstration room is often not viable under real-world conditions, the sales manager emphasizes.
In solving this problem, QRS was able to benefit from its close partnership with KUKA, which has been in place for a good 15 years: When it comes to camera systems, KUKA turns to Munich-based partner Roboception, which offers not only a reliable 3D stereo sensor in the form of the rc_visard, but also develops modular software components that are ideally suited to applications such as those of Danish company Danfoss. “Using our SilhouetteMatch software, the rc_visard recognizes components on the basis of a tem-plate created either from CAD data or from data generated directly by the sensor,” ex-plains Dr. Michael Suppa, CEO of Roboception. Interaction with KUKA robots is very quick and easy using a standardized web interface and graphical user interface.
What this means in the case of Danfoss is that the rc_visard reliably detects the position and orientation of the flat, unordered objects on the flat paper surface and also provides the robot with the gripping points at the same time.
“A 2D solution was quickly ruled out for this project,” explains Suppa. “The paper slipsheets are not always completely flat, or may even be oily due to the components.” In tests with other systems, the camera had sometimes misinterpreted impressions as workpieces. The Roboception software, on the other hand, recognizes exactly which components are supplied to the robotic cell and transmits the appropriate gripping points for a KR CYBERTECH from KUKA. This removes the workpiece and takes it first to a marking laser.
The components then pass via a conveyor belt into another cell, where a KR QUANTEC automatically loads them into the grinding machine and unloads them again. In the subsequent cells, KR CYBERTECH robots feed the machined workpieces to a “washing system”, sort them into containers or load another small grinding machine.
For those involved, the project was very much a case of jumping in at the deep end. “Implementation of the perception solution was a new experience for us. When we venture to take on something like this, we only select partners of whom we are absolutely convinced and who we are sure will support us in the long term,” emphasizes Olav Sjørslev from QRS. He has only positive things to report about the cooperation with Roboception and KUKA. “For this project, everyone involved willingly went the extra mile in terms of transfer of know-how and time invested.” But the effort was worth it in many respects. In this way, not only was the client satisfied, but the successful integration of the camera system from Roboception also ensured direct follow-up orders at integrator QRS.
“We learned a great deal from this job that will help us to realize other projects,” says Sjørslev. “What is the influence of light conditions, what interference can occur on the lens, how far away can parts still be recognized? We now have concrete answers to these questions.” Danfoss, too, is pleased with the solution from KUKA, Roboception and QRS. The automation not only accelerates and stabilizes the hydraulics expert’s production processes, but simultaneously ensures greater safety at work for its employees.
There is another important point to be made: “By integrating other software modules, our hardware can solve a wide variety of tasks,” says Dr. Michael Suppa of Roboception. “Danfoss thus now has a variable 3D vision solution that can be easily adapted to other tasks as required.”

In this context, PAL Robotics participated in a project called SANDRo, (Semi Autonomous Night and Day Robot) funded by DIH-Hero which aimed to deploy an innovative robot that provides assistive services to people with difficulties in Activities of Daily Living (ADL).
The project was carried out at the social and health care centre El Carme, located in Badalona, Spain. In this centre the staff dedicate a lot of time to certain daily tasks that prevent them from allocating more quality time to patient care. Among these tasks are conducting rounds in the rooms to ensure patients are well, responding when a patient presses the call button, or entertaining them with daily tasks, such as encouraging them to exercise.
El Carme is part of Badalona Serveis Assistencials (BSA), a municipal organisation that provides comprehensive health and care services to the population in certain areas of Barcelona.
The SANDRo solution is based on PAL Robotics’ TIAGo robot, with various integrations provided by project partners. TIAGo is a robot that combines perception, navigation, manipulation, and human-robot interaction skills. TIAGo is an omnidirectional mobile base with a lifting torso and a 7 DOF arm with a payload of a minimum 3kg. The design of the arm and torso and the implementation of a whole-body-controller software allow for flexible motions as well as reaching the floor to pick up fallen objects. Additional equipment can be easily mounted on the platform, such as grippers that will allow the robot to manipulate and tiny objects that request significant dexterity such as medicine cups, pills and credit cards.
In this regards, TIAGo is well-suited for applications in the healthcare and light industry sectors, specifically due to its manipulation capabilities and modular design.
TIAGo has been configured to respond to the specific needs of the staff at the Centre Sociosanitari El Carme hospital. The project focused on how TIAGo can help reduce the time nurses spend on certain daily tasks related to patient care. Specifically, the project addressed how to assist staff with 3 specific daily tasks using the TIAGo robot.
The main benefits of this project, both for healthcare professionals and patients, are significant. For caregivers and nurses, the integration of the TIAGo robot offers a solution to the time constraints and multiple demands they face in providing care to the elderly. By automating routine tasks that nurses may not have the time to complete thoroughly, the TIAGo robot ensures these important activities are handled efficiently. This allows healthcare professionals to allocate more quality time to meaningful interactions with their patients, enhancing the overall quality of care.
For patients, the implementation of TIAGo brings several advantages. It increases their physical and mental well-being, providing support and entertainment in their daily lives, stimulating them with their tasks, and enhancing their social interaction. TIAGo serves as an emotional support, ultimately improving their quality of life.
At PAL Robotics, we're thrilled to have been part of this project because it lets us apply our innovative technologies to address significant challenges in healthcare. We conducted trials in several care centres and test facilities across Europe. Contributing to improving the quality of life for this population segment is a fundamental part of our mission, and this project gives us the opportunity to do so in collaboration with other partners and experts in the field, such as the Broca Living Lab (within Broca Hospital) in Paris, De Zorggroep, a healthcare provider in the Netherlands and HIT (Heemskerk Innovative Technology). We're excited to see how our technology can make a difference in elderly care and support the healthcare staff who attend to them.
Traditional automation perfectly fits with high volumes but it is often hindered by the kind of heterogeneity and product diversity which characterises the above mentioned markets and needs.
Bringing together Artificial Intelligence (AI) techniques and robots is necessary to simultaneously deal with high volumes and high product heterogeneity.
Comau has thus combined its historical experience in automation with the deep knowledge of vision systems in order to design and develop a deep neural network able to identify any kind of box without constraints in terms of lighting conditions, dimensions, colours, texture and even title position with respect to the ground, in fact, the Comau solution if effectively able to pick angled boxes thanks to the 6 degrees of freedom offered by its robot family.
The newest solution in Comau’s MI.RA family (Machine Inspection Recognition Archetypes) utilises 3D cameras and advanced algorithms to reliably detect and depalletize boxes and containers in a fast, accurate and cost-effective manner.
From standard boxes with well-known sizes to single SKUs with uncertain positions, MI.RA/Depalletizer can also manage mixed-type SKUs with unknown sizes, positions and palletizing geometries. To achieve such flexibility, the intelligent, all-in-one solution is designed to easily recognize and react to different packages taking their contents and final location into account.
With its inherently intelligent advanced robotics and powerful vision systems, MI.RA/Depalletizer ensures absolute flexibility in terms of packaging types, pallet logistics, robotic technologies and the grasping strategy. Furthermore, MI.RA/Depalletizer can significantly reduce commissioning time by up to 70% in both single-type and mixed-type SKUs .
From the picking of products to the packs that will contain them, MI.RA/Depalletizer automates the entire depalletization process, optimising operational logistics as well as your bottom line.
The vision system algorithm has been developed aiming at hardware agnosticism, which allows it to be compatible with all the 3D cameras. As shown in Figure 2, which summarises the technical pipeline, the deep neural network has been trained on grayscale images for different boxes, colours and textures. The bounding boxes provided by the AI engine are then used to optimise the postprocessing on the point cloud, which returns a 6 degrees of freedom pose estimation as well as the prioritisation and the accuracy of the picking. The robot picking can then proceed straightforwardly.
As all the other Comau vision system products, Mi.Ra Depal is offered as a standalone vision system as well as a turn-key solution: integrating a wide range of different robots and design and engineering layout and solutions in order to adapt and solve the specific customers’ needs.
The robotic cell had already been operating at the Sabetha Kansas production facility (USA). It’s included Panasonic Robot and a two-in-one 1-axis positioner for a quick parts changeover. However, before ABAGY, it was used for a limited number of parts, as the programming was tedious.
ABAGY has installed machine vision and other hardware and made it compatible with its proprietary software. As a result, the setup time has been reduced dramatically - only 10-15 minutes for a new product - and the robot can be used for much more products. That’s a big win for Schenck Process with its high-mix production.
Thanks to new technologies such as AI and machine vision robots become autonomous. They can see the part and understand the task. Workflow simplifies significantly. Robot cell control no longer requires programming skills.
The employees upload a 3D model of the part (from the CAD). The system automatically finds the weld joints on it. Then they choose the welds and the parameters they need (work and travel angles, offsets, weaving, etc.). No programming is required. Mathematical algorithms automatically generate the robot trajectories. This happens in minutes.
The next step is scanning the part using machine vision. The algorithms compare the previously uploaded 3D model and the real part. The system finds possible deviations and adapts the robotic path on-the-fly.
“Manufacturers have been facing labor shortages, especially during the pandemic and there is an urgent need to deploy automation,” says Yokoyama Eisuke, CEO and President of Yokoyama Kogyo.
His company needed to automate part of its production process on the metal stamping machine. At the same time, employees also needed to maintain access to the pressing machine safely.
Collaborative application is a clear choice for Yokoyama.
Combining the OnRobot RG2 gripper and AUBO cobot, the manual processes of loading and unloading parts are fully automated. Notably, the collaborative application does not require a big footprint and it is able to work safely alongside employees; no safety fence is needed.
With unlimited customization to fit various needs, the small, lightweight RG2 gripper is perfect for tight spaces. The fingertips of the gripper can be easily customized, fitting the product shape for stable gripping
“OnRobot provides simplicity and ease of use, which saves us a lot of expensive engineering hours that are usually required with typical automation projects,” says Mori, Assistant Chief of Technology for the Manufacturing Department.
Employees of Yokoyama now do not have to perform strenuous, repetitive work on the machine. They no longer need to be stationed at the machine for hours, but they are able to focus on higher-value duties. Collaborative application has helped Yokoyama achieve an overall 35% cost reduction while maintaining work safety and high-quality output.
Established in 1951 in Toyota City, Japan, Yokoyama Kogyo is a leading metal stamping manufacturer for the construction and automotive industry. The company has around 200 employees in Japan. Yokoyama patented a pressing technology called SFP (Smart Forge Press) method, which has been widely adopted in Japan. In 2010, Yokoyama established a manufacturing facility in Thailand to fulfill the continued growth of the automobile industry in the region.

Heemskerk Fresh & Easy has been ahead of the curve in creating products that make it easy for its customers to lead a healthy lifestyle. Wim Heemskerk started the company in the 1960s, selling chopped vegetable soup mixes that quickly became a regular dinner item in Dutch households for the convenience they offered to busy consumers.
Sixty years on and Heemskerk is on top of its game, delivering anywhere between 3.5 million to 4 million fresh convenience products every single week to retail companies and fast food chain across the globe. Buoyed by a growing preference for more plant-based, minimally processed food, Heemskerk has expanded its operations to offer more than 400 products such as fresh salads, ready-to-cook meal boxes and pre-cut vegetables and fruit that can satisfy diverse customer needs and tastes.
As its expansion took shape, Heemskerk faced challenges in the supply chain as the company needed to make just-in-time deliveries of fresh food products to supermarkets across the country. As food such as fresh salads and ready-to-cook meals have very short shelf lives, typically of three to four days, being able to reduce the amount of time that the food spent in the supply chain is crucial for Heemskerk and its supermarket customers who can stock the food for longer and reduce potential wastage.
This coupled with diverse food demands from end customers meant that the existing manual order picking and dropping operations at the Heemskerk facility was no longer sufficient for the company. A shortage of skilled labor to support the large-scale process also increased manufacturing costs. These pain points prompted Heemskerk to invest in a robotics automation solution from ABB that offered the speed and flexibility to support the company with faster manufacturing processes and shorter lead times to supermarkets.
ABB supplied a robot-centric solution to automate the order picking operations at Heemskerk’s production facility. At the beginning of the product flow is an ABB IRB 660 four-axis robot that removes crates containing the orders for a particular supermarket and places them on a conveyor belt. The crates then move to the order picking zone where six IRB 6700 six-axis robots positioned on a track pick up the crates and place them in “pigeon holes” that are designated for that supermarket. Two other IRB 6700 robots positioned on the other side of the order picking zone consolidate the order picked crates to create stable mixed high stacks. These crates are finally picked up by another IRB 660 four-axis robot that places the crates onto dollies to be transported directly to the supermarket. This form of order picking makes the solution more robust as it can seamlessly process an endless variety of orders – a concept that is very useful to the daily changing volume orders of the fresh food industry.
While there are many benefits to be gleaned from the ABB robot solution, one of the most important advantages for Heemskerk and its supermarket customers is that the solution reduces the amount of time the fresh produce spends in the supply chain, thereby extending its shelf life, minimizing wastage and creating a more sustainable solution for the fresh food industry. About one-third, or 1.3 billion tons, of all the food produced and packaged for human consumption is wasted every year, according to the United Nations’ Food and Agriculture Organization, and industry players are increasingly ramping up their efforts to reduce the scale of wastage.
The automated order picking capability of the ABB robotic solution allows logistics operators to cross dock products directly to supermarkets. The ability for retailers to receive already order picked quantities for each store increases its shelf life by about one day. On the other hand, in more traditional food logistics processes, the packaged food is first stacked in the supermarket chain’s storage unit where employees pick and stack the food according to orders from each of its stores only after which they are transported the stores. This process typically takes about half a day, lowering the already short shelf life of fresh and natural food.
"Over the last ten years, supermarket customers are asking food processors like Heemskerk to deliver their products, already order picked for each store. With the ABB system, Heemskerk is able to smoothly handle the high demanding task of order picking,” said Chris Vleeschouwers, the Sales and Marketing Manager for ABB’s Consumer Segments and Services Robotics. “Today, the ABB robots are able to process 300 to 400 crates per order. Previously, about 30 to 40 people were needed to perform the same task.”
Another big advantage for Heemskerk is the flexibility that the ABB system offers. With rapid yet precise movements, the ABB robots are able to quickly adapt to varying demands from supermarket and grocery store customers, whose volume and variety demands change almost every day and according to seasonality.
Unlike traditional logistics automation that typically handle individual units in a time-consuming order picking process, the ABB robotic solution enables Heemskerk to deliver more than 60 large scale order picked deliveries every day. While the system processes over 800,000 crates every week, it can handle double or even triple that volume without needing any changes. On one hand, this flexibility allows Heemskerk to quickly ramp up volume based on demand without added investment and on the other hand the solution eliminates underutilization of the automation system on the rare days when demand is low.
“This robotics system helps us by supporting our very fast manufacturing and order picking process because 75 percent of the products (processed) today are in the retail shops tomorrow,” said Peter van Duijvenbode, the Operational Director of Heemskerk Fresh & Easy.
The modular and standardized design of the ABB robot solution makes it very easy to add new robot zones to meet additional capacity. Heemskerk plans to add more robots to its current system to support its future growth.
The entire solution can be installed in relatively low buildings and can even be split up into several modules that need not be necessarily placed next to each other. This makes the automated logistics solution ideal for brownfield applications. Moreover, the system consists of fewer components, meaning reduced maintenance and spare parts costs.
“It is a complex project but the upfront business case is that the system has a Return on Investment (ROI) of three and half years and we are getting close to that number, so for us this is a very successful project,” Peter van Duijvenbode added.

For the employees, this means an enormous relief, which opens up the opportunity to devote themselves to more demanding tasks. In addition, the company benefits from more efficient processes: The collaborative application has doubled the outcome of the CNC machine and ensures higher and more stable product quality.
Founded in 1932, Donk Industries is one of the largest small series manufacturers in the Benelux countries. At its site in Lopik, the Netherlands, around 100 employees produce aluminum parts of all kinds for Dutch and international customers. The foundry, powder coating plant, CNC machining department and product development are all located under one roof. The handling of all processes at one location is a logistical advantage both for the customers and for Donk Industries itself: customers only order from one supplier and receive the requested product assembled. This enables Donk Industries to respond optimally to customer requests.
But this service also comes with it challenges: As a single-item and small-series manufacturer, Donk Industries is confronted with a wide variety of products. At the same time, the company must keep its inventories low and supply customers on time. "In order to stand up to competitive pressure and meet the requirements of a small series manufacturer, we need qualified personnel," says Jaap Zentveld, Assistant Production Manager at Donk Industries, describing the situation.
In recent years, however, the company has been increasingly confronted with a shortage of skilled workers. It was particularly difficult to find personnel to operate the CNC machines - after all, this is a monotonous and time-consuming, yet less demanding task. Long cycle times cause long breaks, which the personnel spent waiting. "Employees who actually have other areas of responsibility were tied to the CNC machine," explains Zentveld. "This also had consequences for the quality and delivery reliability of the products.“
Zentveld began to look for suitable automation solutions in order to deploy its employees more effectively and thus increase productivity while maintaining the same high-quality standards. The company looked at various robotic solutions and found collaborative robots among them. "We are already automating many other parts of the production process with industrial robots," says Zentveld. "However, we have to be flexible with our product variety and the small quantities involved and be able to convert our production lines quickly. In addition, Donk Industries' individual products require special handling. Collaborative applications meet these requirements in particular: They can be flexibly converted for new tasks and are easy to program. In contrast to conventional industrial robots, the combination of Cobot and corresponding end-of-arm tooling can be used directly next to humans and works directly with them.” Zentveld and his team therefore selected a collaborative robotics application with end-of-arm tools from OnRobot.
Today, an RG6 gripper loads and unloads one of the eight CNC machines in Donk Industries' production halls. The gripper is mounted at the end of a collaborative robot arm and is combined with an OnRobot HEX sensor. This force/torque sensor provides the necessary sensitivity so that the gripper can grip workpieces precisely and perform its tasks efficiently. A specially designed loading station, the Robobooster4000 developed by system integrator Olmia Robotics, is a requirement for smooth loading and unloading of the machine. The gripper removes a component from this station and inserts it into the machine. After the milling process, it takes the finished product out and places it in the magazine. The cycle is repeated until all components have passed through the process.
Thanks to the individually adjustable fingertips, the OnRobot gripper can handle objects of different shapes and sizes. The local partner Olmia Robotics helped adapt the robotics solution to Donk Industries products. "With Donk Industries' specific requirements in mind, we recommended an OnRobot gripper," said Peter van Olm, founder of Olmia Robotics and distributor of OnRobot. "Because it is so flexible, we were able to adapt it individually to the application. The concept of the one-stop shop allows us to find the right solution for every application".
The fingertips of the RG6 can now be replaced within minutes. All the employees have to do is loosen a few screws, attach the new fingertips and screw them back in again. This enables them to quickly adjust the gripper to changing workpieces whenever the varied manufacturing process requires it. If new products are added, the employees develop suitable fingertips together with Olmia Robotics. This flexibility is reflected in time savings and better delivery reliability. "With the collaborative application of OnRobot, we have found a solution that exactly meets our requirements," says Zentveld.
The collaborative application has also doubled the productivity of the CNC machine within a short time, while the failure rate has been halved. Even without human intervention, the application runs smoothly and can be used overnight. The constant operation of the machine has even more advantages: "Production is now much smoother - you can tell this from the product quality, which is much more consistent than before," comments Zentveld.
The employees also reacted positively to the helping hand on the CNC machine. "For us, the automation solution from OnRobot is a great relief," says Josine de Groot, employee at Donk Industries. "We can give up a monotonous task and thus have more time to take care of more demanding things - such as quality control or technical drawings.“
Donk Industries does not lose any jobs by automating CNC assembly. In fact, valuable working time now flows into activities that previously could only be performed inadequately. Thus, the application helps to counteract the shortage of skilled workers.
In the future Donk Industries wants to focus even more on automation. "The entire project has shown us that automation is a real enrichment for our company and our employees," Zentveld sums up. "In addition, we can now produce much more efficiently.” Zentveld and his team are planning to automate further CNC machines with OnRobot solutions in order to relieve the strain on employees. In this way, the traditional company remains fit for the future - and ensures that it will be able to support its customers as a competent partner for at least another eighty years.
Climate change is an existential threat to our society. It is agreed by the vast majority that pivoting away from fossil fuels and towards renewable energy is vital to preserving resources and the natural environment and enabling the transformation to a sustainable society. Solar energy is one element of the overall energy mix, and for many countries and regions which enjoy comparatively high levels of sunlight throughout the year it is an ideal solution for decarbonizing the grid. However, a caveat with solar energy is its cost. Solar technology is traditionally difficult and expensive to both develop and manufacture on a mass level.
Thanks to the use of ABB robots, Swedish manufacturer Absolicon has developed what it sees as a gamechanger for the widespread adoption of solar as an energy source. The company manufactures solar collectors, which are essentially troughs which track the sun across the sky to catch its rays. A parabolic reflector focuses the solar irradiation on a receiver, which then turns it into heat, which in turn generates steam at up to 160 degrees. Absolicon’s solar collectors are the most efficient in their class and are ideal for industrial companies and district heating networks.
Almost all industries require heat for production processes. In textiles manufacturing for instance, almost two kilograms of coal are burned for every one kilogram of cloth produced. Beer production burns two tons of diesel for every 100 liters of beer. Even industries that are not widely considered to be energy intensive can require significant amounts of heat. Drying tea leaves, for example, requires the burning of five tons of firewood for every one ton of tea leaves. Solar collectors like Absolicon’s can harness the clean energy of the sun to produce this heat while generating zero CO2 emissions. To give some idea of their emission-saving potential, every square meter of a solar thermal collector can produce the equivalent energy of 100 liters of oil.
Solar collector panels are highly complex, requiring production processes that are extremely precise, highly efficient and cost effective. To achieve this, Absolicon and ABB have developed the world’s only complete solution for the mass production of concentrated solar collectors, in Absolicon’s factory in Härnösand, Sweden.
The degree of automation has increased production drastically. Where previously Absolicon was able to produce three solar collectors per day using manual production methods, with units assembled in the field, the newly installed robotic production line, which uses two ABB robots, has enabled the creation of an automated factory production line that is capable of producing a single collector in as little as six minutes. By the time you finish reading this article a new solar collector may well be ready for delivery.
The newly automated production process significantly reduces the skilled labour requirements and production cycle time for each collector, substantially reducing the overall unit cost. The consistent performance of the robots also enables each collector to be assembled in the same way, ensuring that the highest levels of quality are maintained throughout production and that the assembled collectors can offer optimum performance once installed.
Crucially, Absolicon has not just developed the solar collector itself, but intends to export the whole robotised production unit as a turnkey solution, so that collectors can be manufactured locally. This could have significant ramifications for the solar industry, making advanced solar technology both more affordable and more accessible for companies, organizations and governments across the world.
"Developing an automated production process enables our global business case by radically reducing the price of our solar collectors, while manufacturing them consistently to a very high quality. The productivity offered by ABB’s robots means we can make solar energy compete on price with conventional industrial heating for the first time," says Joakim Byström, CEO of Absolicon. “Our new automated production line can produce a complete solar collector every six minutes, so while competitors rely on a manually intensive manufacturing process, we can now do it with five people, two robots and a fraction of the components. This will be key in helping to meet the growing demand for renewable technologies to help meet global carbon emissions reduction targets.”
“We are pleased that ABB’s robotics solutions are accelerating the productivity, quality and cost efficiency of Absolicon’s production line to enable them to bring a renewable energy product to market at a competitive price,” says Sami Atiya, President of ABB’s Robotics & Discrete Automation Business Area. “In helping Absolicon to accelerate their production from three units a day to one every six minutes, our robotic solutions are playing a key role in accelerating the global adoption of sustainable technology, ensuring Absolicon’s production partners are able to consistently produce solar collector panels globally.”
The next phase of the project involves supplying complete robotic production lines to manufacturing partners across the globe and ABB and Absolicon have agreed they will collaborate on the development, sales and marketing of the robotic production line worldwide.
“Our vision is to enable a cost-effective mass-production of solar collectors across the world, to produce heat directly from sunlight,” adds Byström. “Our work with ABB to create this automated production process is a key enabler to realize our vision, while ABB's global service organization will be a very valuable resource for our new customers as we roll-out our new automated production line globally.” The first installation has already been delivered to a partner in China, and framework agreements for the acquisition of robotic production lines have been signed with businesses in a dozen countries, with ABB supplying the robots for all new installations.

175,000 units smart and connected EVs are to roll off the production line annually at the Gemlik Togg Technology Campus in western Turkey by 2030. The turnkey paint shop project was awarded to Dürr in 2020 and a second order for the final assembly system followed in 2021. Together, they covered all plant engineering, application technology and marriage, including fully automatic screwdriving stations and inspection equipment. “The pretreatment and cathodic electrocoating systems are already rated for the final expansion stage, while the plans include provision for doubling up of all other power units in the layout. Therefore, Togg can react quickly if the capacity requirements increase, for example, by adding a second oven or an entire line,” explains Bruno Welsch, CEO & President Paint and Final Assembly at Dürr Systems AG. Production started only recently.
Togg initially opted for a lean painting process to minimize energy demand. The base coat and clear coat of the internal and external paint finish are applied in a single topcoat line with integrated primer application, eliminating one drying phase. The solvent-based paints contain 30 to 35 percent more solid content than standard paints to achieve the required layer thicknesses with lower discharge rates.
The EcoDryScrubber dry separation system concentrates the solvents released into the exhaust air fully automatically and separates the overspray –saving resources in many ways. The system requires virtually no water and very little energy for air conditioning, which is usually one of the highest energy consumption processes in painting. Spray booth air recirculation of up to 95 percent means that heat and electricity consumption is reduced by up to 80 percent and 50 percent, respectively. This reduction also pays off economically, with energy consumption reduced by up to 60 percent. Togg goes well beyond the legal requirements with one additional measure to protect the environment. The Oxi.X, a regenerative thermal oxidizer (RTO) that can be operated auto thermally – in other words, without a primary energy supply for the burner – disposes of the booth exhaust air.
Togg insists on high standards not only for environmental friendliness but also for coating quality. Next-generation Dürr robots apply the paint, including the seven-axis EcoRP E043i, which is mobile enough to paint doors from the inside and open tailgates. A unique technical feature is the EcoBell 3 atomizers equipped with two main needles, which apply colored clear coats for particularly shiny surfaces. The second main needle eliminates the time-consuming rinse cycles previously required, reducing detergent consumption and ensuring the fastest color changes within the required cycle time.
Togg benefits from NEXT.assembly in the final assembly area. Whereas individual components were previously the focus, the final assembly system is now considered a whole unit to make vehicle assembly as efficient as possible. NEXT.assembly bundles all of Dürr’s technology and consulting portfolio for maximum efficiency in the vehicle assembly process. The result is the most comprehensive final assembly portfolio on the market to-date. It is available as a complete solution or in individual modular parts. “Togg is the first car manufacturer to choose a complete solution from our final assembly offering. We developed a highly customized, resource-conscious solution that results in high synergy and efficiency at all levels along the whole line with precisely coordinated processes,” reports Andreas Hohmann, Vice President Consulting & NEXT.assembly.
Dürr’s overhead conveyors ensure efficient processes. A total of 57 lightweight overhead conveyors transport the vehicle doors to a separate door pre-assembly line. Another 50 heavy overhead conveyors are provided for transporting the bodies. With the potential for future digitization, subsequent process integration or maintenance analysis tools is possible.
One way to save material in pre-assembly is through precise dosing with the EcoShot Meter, which is suitable for almost all thick matter for sealing and gluing. The dosing unit, which is suitable for 1K and 2K applications, can also apply PU adhesives for window gluing. At Togg, these are used in the fully automatic gluing of windows and panoramic glass roofs. The automated process happens while the body is being conveyed (line tracking), making it much more efficient than the previous stop-and-go process where the vehicle conveyor had to be stopped for installation.
Togg is ideally equipped for the specific marriage process for electric vehicles with a line divided into seven individual stations, including the fully automatic x-bolt screwdriving station with six individual spindles. They fasten the front-axle module, the battery, and the rear-axle module automatically with a total of 30 screwing points. A downstream manual screwdriving station fastens another 14 screwing points, which can be easily automated in the future.
The ProLine Cube guarantees faster and more high-quality filling for all media. As the technological core of the filling system, the fourth Somac adapter generation – the ergonomic G4 Blue Adapter – determines the fill quality and process time.
The battery-powered vehicles are inspected and aligned in two complete end-of-line systems by the wheel alignment stands x-wheel, among others. They are equipped with the new x-3Dsurface sensors. These provide 3D measurements of axle geometries and align them with an extremely high level of precision and reliability. The wheel alignment stands are combined with the headlight measurement and adjustment systems x-light as well as the complicated ADAS calibration systems x-DASalign, which are used for calibrating the SVC (Surround View Camera), FLC (Forward Looking Camera), and FLR (Forward Looking Radar). The roll/brake/ABS test stands x-road for dynamic roll, brake, and ABS testing complete the end-of-line system.
“As the principal supplier, we work closely with Togg to meet high environmental and quality requirements,” says Bruno Welsch. The service offering is rounded out by the Turkey-based Dürr team, which will take over the ongoing servicing of the system in the future.

Hundreds of examples in medicine and pharmaceuticals demonstrate how the further development of robotics is opening up new areas in these highly sensitive fields of application. Here is a small selection of pioneering solutions.
One world-first in medical robot technology is the RoboticScope system designed by – again – a startup company, this time from Innsbruck/ Austria. The three founders of BHS Technologies GmbH have designed, to describe it very briefly, a combination of a high-precision robot, a high-resolution 3D camera and an innovative head-mounted display (HMD).
The result: The surgeon is able to look directly into the operating field via a Head-Mounted-Display (HMD). Two digital microdisplays integrated into the HMD directly in front of the surgeon’s eyes show high-resolution, real-time 3D images relayed by the dual camera lenses mounted on the robot head. The position of the robot determines the visible image, allowing the surgeon to operate in a freely selectable and completely relaxed head position.
The surgeon retains control over the exact image field and viewing angle, automatically steering the robot with contact-free head movements. He can easily select the viewing angle of the 8x zoom lenses and even control a sophisticated menu from a microdisplay, allowing the activation and control of further functions.
In this application, the hygienic design and – no less important – the highly precise and jerk free motion of the Stäubli TX2-60L were the reasons for selecting this type of robot. They make sure that the operator always has, in a literal sense, a clear picture of operating field.
As with the entire range of latest six-axis Stäubli robots, the enclosed structure allows for a protection class IP65, with the wrist being IP67 compliant. With cleanroom class ISO 5 as a standard, this six-axis machine allows BHS to save on the potential extra costs of upgrading to a cleanroom version. While in the operating room, the TX2-60L is covered with a sterile sleeve, further preventing any particle emissions and making it ideal for use in these stringent cleanroom environments.
In addition, the new machines are more lightweight, rigid and powerfully motorized, making them even more dynamic. With an accuracy of 0.02 millimeters, they are more precise than ever before.
The six-axis machine is driven by a Stäubli CS9 controller receiving signals from its own digital safety encoders (one per axis) and an integrated safety board. All coordinates of the robot, as well as speed and acceleration, are logged in real time.
Some 500 surgeons around the world have now trialed the RoboticScope. The device is so intuitive that more than 90 percent of users master it after just ten minutes. The TX2-60L contributes to this success by its hygienic design and precise, jerk-free movements, giving just one more example for the use of Stäubli Stericlean robots in pharmaceutical production, innovative medical technology and in the operation theater.
Zellwag Pharmtech AG - a company of the renowned Swiss company Rychiger AG - has recently developed a fully automatic filling and sealing system for hyaluron gel (HA gel). This ingredient is in great demand because it works as a true fountain of youth for the skin.
The Z-810 R-2 machine fills and closes syringes with HA gel not only under cleanroom conditions but also under vacuum because injecting air under the skin is extremely dangerous and must therefore be avoided.
A Stäubli TX2-90 Stericlean six-axis robot is able to handle syringes, vials and cartridges in a confined space. In the first machine of its kind, which was delivered to a pharmaceutical company, the robot receives a tub with one hundred prepared and sterile syringes and holds the syringes precisely under the filling valve in such a way that two are filled at a time. After 50 cycles, all syringes are filled. The highly dynamic Stericlean robot places them back into the tub which is transported by a conveyor system for further processing. In this way, filling rates of up to 2,200 syringes per hour are achieved, the limits here being set by the viscosity of the gel and not by the robot.
A major characteristic of this multi-format line is the high degree of flexibility. Nested and sterile containers with different formats such as syringes, vials and cartridges made of glass or plastic can be processed on the same filling line. The user, in effect, is able to adapt the line to the current demands of the (beauty) market. He can do so in short time because when it comes to programming, there is another unique feature of the Stäubli Stericlean range: thanks to their uniVAL plc interface, the six-axis robots can easily and quickly be programmed directly via PLC from well-known manufactures, in this case a Siemens plc.
This eliminates the need for complex subsystems and interfaces that are difficult to understand, from programming to qualification – and it allows programmers to continue working in their familiar environment without having to learn the robot programming language.
There are robot applications, though, where flexibility is just a minor issue. This is the case in the automated line of Belgian start-up company Texere Biotech. Here, Stäubli Stericlean robots process femoral heads (i.e. the top end of the human thigh bone) in a fully automated line into cuboid implants known as “bone allografts”.
These implants are in high demand as “natural” material for replacing bone material after, for instance, tumor surgery. But the supply is smaller than the demand because up to now, the “bone banks” relied on manual production methods with poor yield. And the danger of cross-contamination could never be excluded totally.
Dr. Denis Dufrane, founder of Texere, worked for a number of years as a specialist in bone grafting – and he settled his company with the desire to supply a greater number of allografts. The solution: Six Stäubli Stericlean robots are installed in a hermetically sealed and extensively glazed 40ft module. The femoral head is inspected, cut by a fully encapsulated waterjet machine, chemically treated, sterilized and inserted into vacuumed vials.
Hygienic standards are extremely high: For each hip bone, a separate kit of vials, labels and even grippers has to be provided. When selecting the robots, there was no doubt that Stäubli proved to be the best solution because the Stericlean robots offer unrivalled hygiene standards.
Dr. Dufrane is satisfied that the time, effort and capital investment in the system has been worth it: “For the first time, we have realized a completely automated system for processing bone tissue. The results include a significantly better yield, higher volumes and lower costs. Above all, full automation gives us a very high level of safety. Contamination, including cross-contamination risks, can be excluded. This is poised to become now a new gold standard for bone implants.”

Since its foundation in 1931, the Saxonian Bahner und Schäfer GmbH has been producing technical springs and bent parts for numerous industries in the third generation. In two production halls at the Oelsnitz site, the family-owned company manufactures components for customers throughout Europe and North America, always precisely tailored to individual requirements and special applications. Small and large series are covered by Bahner and Schäfer as well as single pieces and prototypes - in numerous variants and made of different spring steel types. With a new robot cell from ICM built around a Kawasaki robot, the traditional company is getting ready for the future.
Managing Director Tabea Schäfer, who has been responsible for the technical springs division since taking over the company in 1993, is focusing on automation and technical innovations in order to promote the long-term growth of her company. Thus she decided early on to focus primarily on small and medium-sized series in order to be able to supply small and medium-sized customers flexibly and precisely.
A personal relationship with her customers and fast response times and deliveries have proven to be key factors for Tabea Schäfer's success from the very beginning.
For a long time, some production processes were still carried out manually by the employees at Bahner and Schäfer, such as subsequent chamfering or the individual positioning of parts for subsequent heat treatment. This procedure not only required more time and money, but also always presented the risk of deformation.
For Tabea Schäfer it was clear for a long time that something has to happen. The challenges have changed rapidly over the years, today automation is an important factor to meet the demand and special requirements of customers from many industries.
This line with six Stericlean robots processes humane hip bones to cuboid implants.
At the opening of the SME 4.0 Competence Center in Chemnitz, she came into contact with ICM on the recommendation of other companies and was quickly convinced. The ICM - Institut Chemnitzer Maschinen- und Anlagenbau e.V. is a non-profit research institute for innovations and system solutions in mechanical and plant engineering, with a special focus on small and medium-sized enterprises. Although three other suppliers were also guests at Bahner and Schäfer, ICM was able to score points above all with its broad expertise in various fields, says Schäfer: "Our project was complex and not all developments could be planned in advance from the outset. We don't have our own in-house engineer, so it was all the more important for us to have a qualified contact person who not only tells us how it's done, but also receives, checks and implements our ideas in a targeted manner. The combination of ICM and Kawasaki Robotics was therefore exactly right for us".
The premise of the search for an automation solution was and is simple: more flexibility.
"The bending machine for production is flexible, so the robot system must be too," says Schäfer.
Before the first robot came along, there were concerns among the staff, but for Tabea Schäfer it was clear: "If we miss the opportunity to automate now, we might not have any orders in 10 years because we will be too expensive then. That way we will remain future-proof in the long term". The employees' worries quickly disappeared and the benefits became clear: the growing number of new jobs could be handled without pressure, and automation provided the necessary breathing space.
In addition to relieving the strain on the employees, automation also had another important task to accomplish: After reunification, many older employees with a great deal of specialist knowledge were hired, who are now gradually retiring. The generation change that took place in this way brings many young employees who value family-friendly working hours. The use of the robot system provides the necessary planning and automatic scalability of production.
After the decision for ICM and Kawasaki Robotics was made, the implementation started promptly. The project turned out to be challenging, but due to a close and flexible cooperation it could be implemented in a timely manner.
"The planned robotic cell had to integrate itself not only into the available space, but also into the already established process chain - flexible and easy to operate," says Anton Ivanov, ICM project manager. At the center of the system: the Kawasaki Robotics RS010L. The RS010L is part of the universal R series for small to medium payloads, suitable for assembly, material handling, machine loading and many other applications. It has a maximum load capacity of 10 kg and a reach of 1,925 mm. Its special design enables the high-speed robot to have a longer reach and an extended working range.
The system automates the previously manually executed separation process of the bent parts, which at times was performed by up to 4 employees: The RS010L robot removes the parts from the bending machine and feeds them to a register for suspension or to an ICM designed end finishing machine - precisely and without unnecessarily bending or jamming the parts. An X/Y linear axis system with 3x2 m travel gives the robot, which is installed on the ceiling, additional room to move and acts as a seventh and eighth axis. "The design of a stiff portal as a three-legged construction was very challenging, as a classic four-legged portal was out of the question under the given installation conditions. Its vibration behavior was optimized using modern FEM simulation," says Anton Ivanov. Since flexibility plays a key role and the system has to be adapted quickly to different bent parts and materials, the robot can automatically pick up the appropriate gripper at a tool change station - ICM relies on gripping systems from the specialist Zimmer Group.
After its commissioning in April 2019, the new plant was able to quickly optimize production through automated handling: The number of pieces produced is significantly higher, and if necessary, night-shift operation is also possible without any problems, thus allowing for much more flexible production. "Previously, there was no shift work at Bahner and Schäfer, but the robot offers the necessary flexibility and can, for example, completely automatically handle its own shift. Furthermore, the system frees the workers from monotonous work and the production assistants can devote themselves to numerous other tasks," explains Marcel Ott, who is in charge of software development for the project at ICM.
The system can be adapted for new parts in less than 15 minutes. This means that Bahner and Schäfer can change over production in the shortest possible time. The system around the Kawasaki Robotics RS010L also ensures consistently high quality: the deformations of the bent parts that often occur in manual operation are a thing of the past.
"All information on the status, the current workload and the current cycle can be read out and visualized at any time. This means the system can also run overnight or over the weekend - with a full overview," says Marcel Ott.
The robotic cell can be adapted to new productions in the shortest possible time thanks to a quick gripper change and the possibility of attaching different parts.
The automation at Bahner and Schäfer continues to progress: Tabea Schäfer and her team are planning to map even more applications with the existing Kawasaki robot - this is how the investment already made is to be optimally utilized. In addition, in the future especially younger employees of Bahner and Schäfer will be trained in the handling and programming of the robot.
The demands on production are also growing: in the future, even more complex bent parts and springs are to be produced, and more often small quantities of individual parts. There are also already plans to use robots on other machines for removal in the long term - for example, for the post-processing of tension springs for reworking. When it comes to automation, the traditional company is taking a step-by-step, but long-term and continuous path.
This is where Sewts, a Munich-based start-up, comes in with its new robot system, VELUM, that can perform this task without causing creases.
“The market potential is significant," explains Sewts co-founder Till Rickert. He estimates that there are around 25,000 laundry businesses worldwide that could benefit from the technology. The first VELUM systems have already been installed, with customer Greif Textile Mietsysteme in Wolfratshausen, Bavaria, using the system since November 2022. The robot system processes an average 500 to 600 textiles per hour, automating a task previously performed manually.
Currently, the performance of the VELUM system is comparable to that of a human operator, but with continuous over-the-air software updates, the system’s range of functions is continuously expanding, improving its efficiency. Depending on the workload, the VELUM pays for itself after one and a half to two and a half years, according to Rickert.
“One initial challenge was the tight installation space in which very fast movements have to be executed”, explains Rickert. Sewts used two simulation tools during development. FANUC ROBOGUIDE software to analyse robot movements and space requirements, and advanced material simulation software to simulate the behaviour of different types of textiles. The system installed in Wolfratshausen uses two FANUC M-10iD robots with a payload of 12 kg and a range of 1,400 mm.
The VELUM system’s centrepiece is its intelligent software that can analyse deformable materials and predict their behaviour when gripped. When combined with a FANUC robot and a 3D camera system, the software can identify textures, seams, and corners of individual textiles, locate them in space, and create control commands, enabling the robot to grasp textiles at an ideal point in real-time.
Sewts plans to increase the number and performance of VELUM systems gradually. The start-up is already working on the next innovations, robots with vision systems to process textile returns for large online retailers in the future. Due to labour shortages, such returns are often processed in far-away countries, resulting in long transport routes and wasted goods. "In the future, thanks to automation, such processes could take place close to the customer," Rickert hopes.
Chengda Biotech is producing different vaccines, made with bio-technological processes. © Stäubli
The production of vaccines by means of biotechnology is a complex process that has to run steadily and under stable conditions. These are good pre-conditions for automation, which is exactly what Chengda Biotech has achieved.
The company whose full name is Liaoning Chengda Biotechnology Co. Ltd. Established itself in 2002 in Shenyang. Today, more than 800 employees are here producing human vaccines. The two main products being produced are a rabies vaccine („ChengdaSuda“) and an inactivated encephalitis vaccine („ChengdaLibao“), both produced in annual quantities of about 10 million copies. Furthermore, Chengda Biotech has succesfully developed vaccines to fight other diseases like hepatitis A, HPV and influenza - all of which are manufactured using biotechnology. Here, the company makes use of a high-density bioreactor platform.
For the production of the hepatitis A vaccine, a new factory in Benxi was established. Its aim was to produce 3 to 4 million units per year while making use of a high degree of automation.
At Chengda Biotech in Benxi, a great example of automating new production takes place – robots fulfil the sensible task of handling cell factories. These are frames with 160 trays contain a nutrient solution in which adherent cells are inoculated. The cells are growing, while the medium in the trays needs to be changed. In a second step, virus-infected cells and virus media are added. Finally, the virus – which is the highly effective vaccine – can be „harvested“.
The task for the Stäubli TX200 Stericlean robot is to grab these frames, which are manually pushed to the positioning point. In order to do so, the robot positions its arm in front of the frame where a vision system installed at the end of the arm detects the exact position where the clamp connects. For this task, a Stäubli connecting system is employed.
The TX200 Stericlean then handles the cell factory and places it at the operating site. While doing so, it carefully shakes the frame in order to distribute the liquid evenly. Then the robot deposits the frame at the scheduled place where the cells are growing.
The robot performs a manoeuvre called an „oscillation flip“. Here, the robot regularly shakes and flips the product for long periods at different stages of cell culture. The entire cell culture process lasts more than ten days, with high requirements for robot stability.
At the stage when cells are added, the purpose of the oscillating movement is to evenly distribute the medium and the cells in the trays. At the fluid exchange stage, the cell fluid is poured with the help of the robot; at the virus harvest stage, viruses and cells in each layer are harvested, again supported by the Stäubli TX200.
One reason to automate this complex process was the desired stability of the environmental conditions, including the temperature. Because the robot reduces manual operations and the working environment temperature is unchanged from the entry and exit of the staff, it can better ensure the uniform stability of the finished product. Furthermore, then highest levels of cleanliness are achieved: The original process environment was GMP A + C. After using Stäubli robots, it was upgraded to the highest level, GMP A.
For obvious reasons, the production environment of the cell factories needs to be regularly – about once or twice a month – disinfected. For this process, Chengda Biotech uses VHP (Vaporized Hydrogen Peroxide). While this would not be possible with a normal robot, the Stäubli TX200 Stericlean is designed for such demanding environments, as its name denotes. The surface of this type of robots has a special coating, the key structure is made of stainless steel, and the entire housing is fully sealed. Therefore, this robot is resistant to hydrogen peroxide and other highly-efficient cleaning methods.
From the viewpoint of Chengda Biotech, the robot-supported automated cell production also offers the advantage of reduced investment and operating costs. Following the installation of the robot, the number of CO2 incubators was reduced. At the same time, consumables such as protective clothing for the staff reduced, too, as well as the energy consumption of the temperature control.
Another point is safety and stability: As workers do not need to enter the factory room, the danger of contamination is minimized. With a temperature of 37°C and a 5% CO2 proportion in the breathing air, the conditions are far from perfect for the staff. Furthermore, the overall weight of more than 100 kg for a single cell factory frame simply requires some kind of automation. Chengda Biotech decided to fully make use of this principle.
Director of biological vaccine production sums up the results: „The robot solution offers lower cost and higher efficiency. It occupies less space, the process design is more flexible and – what is most important – it guarantees a high and stable quality of the vaccine that we produce.“ The comparison between several robot types and brands came to the following result: „Stäubli Stericlean robots have an advantage in stability and they are the only robots that meet the GMP A level requirements. There are also many successful application cases in the pharmaceutical industry. In the experimental comparison, the use of these robots exceeded our expectations. Stäubli has also provided high-quality services and technical support – including pre-sales simulation, after-sales service and training.“
The exceeding of expectations led to a fast decision: Due to the research and the experiments, the customer's confidence in this solution and the Stericlean robots product had grown, so the order increased from two to three. It is the first successful application of a Stäubli TX200 Stericlean aseptic version in the domestic bio-pharmaceutical field. Stäubli China expects that other companies will follow this path of automation: At present, there are 48 vaccine companies in China, and more than half of them use cell factory processes which require handling and oscillating of the trays in which the vaccine is cultivated.
At Okura Kogyo, the staff would manually load and unload workpieces (rollers) from the processors to trolley. The manual process needs to be done carefully to avoid damaging the workpiece. Like other manufacturers globally, the company is also facing labor shortages. As such, the company was looking for a way to optimize their current resources and to increase productivity and efficiency.
“To survive and thrive in an uncertain and rapidly changing world, we need to innovate at speed and to keep pace with technology and industry change.,” says Takashi Totogawa, Director of Okura Kogyo.
Collaborative application is a clear choice for Okura Kogyo
Combining OnRobot VGC10 gripper and Omron cobot, the manual processes of loading and unloading workpieces are fully automated.
The VGC10 gripper has a customized fixture with 4 suction cups and is programmed to handle 2 rollers at a time to match the production cycle. With unlimited customization to fit various needs, the compact, lightweight VCG10 gripper is perfect for tight space and is able to lift small, odd-shaped, and heavy objects even with a smaller robot arm.
The collaborative application is installed on a mobile container, which can be moved and plugged in anywhere, anytime. It does not require big footprint and it is able to work safely alongside employees; no safety fence is needed.
“Setting up collaborative application was fairly quick, we only took 3 days for the complete deployment.” says Mr. Hiroki Kuribayashi, Sales Manager.
Employees of Okura Kogyo now do not have to perform strenuous, repetitive work on the machine. They no longer need to be stationed at the machine for hours and they are able to focus on higher value duties. Collaborative application has helped Okura Kogyo achieve an ROI of 11% while maintaining work safety and high quality output.
Established in 1964 in Kakogawa City, Okura Kogyo is Japanese manufacturers of logistic equipment and systems. The company has around 139 employees in Japan.

At a trade fair in the German town of Kassel, Bastian Fest, Managing Director of FMO Surface GmbH & Co. KG, met KUKA Sales Engineer Robert Korte, who introduced him to the LBR iisy collaborative robot. The entrepreneur was immediately convinced of the advantages of the cobot. Fest then took a closer look at the LBR iisy at KUKA’s branch office in Siegen and decided to purchase it – easily and conveniently via the online KUKA Marketplace. “The LBR iisy combines several factors that we require: flexibility, ease of programming and suitability for collaborative operation. That is why we purchased it, without knowing exactly where we wanted to use it,” says Fest of this rather unusual approach. As far as the programming of robots is concerned, Fest describes himself as a beginner. Although he did complete a training course at the KUKA College when purchasing his first KUKA robot, a KR CYBERTECH, four years ago. All the more reason for him to be delighted with the new cobot, whose ease of use means that even novice pro-grammers can get to grips with robotics.
FMO Surface, a family-owned company specializing in the finishing of plastic surfaces, was founded in 1999 in Lemgo, in the region of East Westphalia-Lippe, and currently employs 75 people. Around seven million bus connectors are laser-marked with Data Matrix codes (DMC) here every year. A few years ago, the company began to automate various processes. The cooperation with KUKA began with a KR CYBERTECH nano (KR 10 R1420), which is used for palletizing and for tending a laser system. Two years later, another KUKA robot from the KR CYBERTECH series was added, which can turn over, measure and laser the plastic parts to be finished. “Particularly in view of the shortage of skilled workers, automation plays an important role for a medium-sized company like ours,” explains Bastian Fest. The LBR iisy then joined the robot portfolio in March 2022.
The job that suited this new colleague was quickly found, namely in the quality control of bus connectors. Bus connectors are laser-marked with Data Matrix codes, each with a numerical sequence of eight digits, before being installed in controllers. Since multiple components are marked with a DMC and are dependent on one another, reliability is of paramount importance with regard to the traceability of an entire module. For this reason, special attention must be paid to checking the quality and completeness of the Data Matrix codes. This was previously carried out by human employees at FMO Surface, manually, using a scanner. Just in time for the start of spring 2022, the LBR iisy took over this task. The cobot now works hand in hand with laser department foremen like Tim Hertz. Hertz reports: “We save an enormous amount of time using the LBR iisy because we no longer have to scan each part individually. And if the cobot reports a fault, we don’t have to open a cage or stop an entire system, we can simply remove the defective part and replace it.”
Attracting human employees for monotonous yet demanding tasks such as checking Data Matrix codes is becoming increasingly difficult for companies like FMO Surface. Training the LBR iisy, on the other hand, posed no problems. “It took us just 30 minutes to unpack and install the robot and perform initial programming,” says Bastian Fest. With the aid of the KUKA smartPAD pro and the KR C5 micro robot controller, even employees with virtually no experience of robot programming can operate and train the cobot. “The LBR iisy runs on the basis of the new iiQKA.OS operating system, making it easy to install, configure and program,” explains Robert Korte from KUKA. The cobot is not only up and running in just a few minutes, but it can also be adapted to new challenges equally quickly. An enormous advantage for Fest: “We don’t have engineers here, so ease of integration is all the more important.”
Equipped with two cameras, the cobot now checks Data Matrix codes. There are 200 plastic parts on a tray, which are slid under the LBR iisy with its two Keyence cameras. “In the first step, the quality of the codes is spot-checked on the basis of 20 parts,” explains foreman Tim Hertz. “If everything is OK, the cobot moves over the tray again and checks whether all 200 parts are present and all codes are readable.” One camera checks the quality with the associated software, while the second is responsible for completeness. If anything is wrong, in other words if a code is of insufficient quality or incomplete, the robot stops and indicates which bus connector is affected. A human colleague can then replace the faulty part; the tray is checked again and ideally released.
In the past, reports Tim Hertz, this type of quality control for DMCs was much more time-consuming. “When checking for completeness, we had to scan each part individually,” says Hertz. For this, an employee had to take the components out of the tray and subsequently put them back again. Today, with the LBR iisy, this task is performed much faster and more precisely. According to Bastian Fest, the customer – an automation company – specifically wanted an automated solution. This is because installing an imperfect bus connector in the controllers could prove to be costly. Bastian Fest reports: “The bus connector is used as the very first part of the controller. It is soldered, screwed onto a circuit board and the whole controller is built around it. So, if the Data Matrix code is poor, when will that be noticed? In the goods dispatch department!” At that point, the damage is considerable.
The LBR iisy can be integrated into existing processes just as easily as it can be repro-grammed for new tasks. From loading machines to packing or various handling tasks, the LBR iisy has everything under control. “The LBR iisy’s integrated cable routing and energy supply system also enable quick and easy tool changing,” adds Robert Korte. For new applications, the cobot can be equipped at any time with additional accessories from the KUKA Marketplace. For Bastian Fest, this is a real bonus: “With this product, I naturally have something that is highly flexible. It makes no difference to the robot whether I mount a suction cup, a gripper or a camera on the front, but it enables me to cover my entire spectrum.”
The employees at FMO Surface were enthusiastic about the new colleague right away, emphasizes Managing Director Fest. There was no reticence. Robert Korte explains: “Thanks to the safety features, collaboration with people in a single workspace is possible.” Equipped with sensitive joint torque sensors in all six axes, the LBR iisy reacts im-mediately to the slightest contact and offers certified collision protection. This makes it the ideal assistant in any production facility. Bastian Fest is already planning to automate further processes. He notes that the cobot could also provide valuable services in pad printing in the near future. Furthermore, he is also hoping to make use of the larger versions of the LBR iisy with their payload capacities of 11 and 15 kilograms.
FlexArc robotic welding cells © ABB Robotics
From being a single product manufacturer to becoming a global supplier of automotive exhaust products, the rise of Katcon has been remarkable. In just 27 years, the Mexico-based manufacturer of catalytic converters has broadened its portfolio, expanded into new geographies and is now a leading supplier to some of the world’s biggest automotive companies.
As business has boomed across the globe, Katcon has been faced with the need to rapidly increase its production capacity. After some research, the company decided it needed an automated welding solution that could be easily programmed to enhance the flexibility of manufacturing at its factory in Warsaw, Poland by enabling it to quickly ramp up or scale down its production to maximize the efficiency of its operations. In 2016, Katcon commissioned its first batch of six FlexArc cells from ABB. Available in a range of standardised packages, FlexArc robotic welding cells incorporate everything needed for a welding application, including welding robots with superior motion control software, positioner and associated welding equipment, all built on a common platform.
ABB’s Robotics Application Centre in Czech Republic designed a welding cell for Katcon that could be easily replicated to increase capacity. Unlike other welding solutions that need to be created from scratch, Katcon operators can seamlessly upload programs from a previous work cell on to a new ABB FlexArc, using the same jig design. Able to be replicated in any Katcon factory across the globe, the cells help reduce the time and cost involved in modifying production lines to meet changes in customer demand.
Flexibility is at the core of the FlexArc’s design. A significant variable in Katcon’s operations is that the company does not have guaranteed quantity demands from its end customers and needed a solution to mitigate some of this uncertainty.
ABB’s FlexArc is ideal for such a situation as one welding cell can be easily adapted for other products. Depending on the forecast by the end customer, Katcon can set up the welding process and use as many or as few FlexArcs as it needs. The flexibility of the welding cell allows the company to use the same jig to make products for different customers with minimum changes to the design.
“Designing a jig is very expensive, but as the ABB FlexArcs are exchangeable between cells, they offer Katcon a better way to utilize them. If a customer wants more products, Katcon only has to make a few changes to the basic frame of the jig and can start production instead of having to change the entire design which can take up to a couple of months. This expense can often exceed the expense of the entire robotic cell,” says Tomas Kostovcik, Sales Manager/ ABB.
Today Katcon operates 27 FlexArcs at the factory and plans to order more for its upcoming factories. At the Warsaw facility, the company uses three types of welding cells, most of which are equipped with variants of the ABB IRB 2600 welding robot that has a unique combination of high payload capacity, and large working range. Other cells use the ABB IRB 2600ID robots with Integrated Dressing, which are designed to offer higher agility and work in smaller spaces. Three types of ABB high-accuracy positioners and other welding equipment are also used in the FlexArc cells.
The FlexArc cells are helping to enhance both worker productivity and safety. On one side of the positioner, an operator loads the parts that need to be welded on a fixture. The IRB2600 robot located on the other side then welds the parts together. Once the welding is complete, the machine delivers the finished parts to the operator who unloads them and replaces them with new parts. The accuracy and speed of the robot’s welding is enhanced by ABB’s TrueMove and QuickMove motion platforms that optimize the welding path, reducing re-works and lowering the production cycle time.
The integrated design of the FlexArc offers an increased level of safety during the welding process. Metal sheets cover the electrical installations and wires are enclosed in special steel frames. This also protects the cell from sparks created during the welding process. All ABB FlexArcs are delivered with fume hoods that can be connected to fume extraction systems that are necessary to protect human workers and keep the working cell free of debris.
Every FlexArc cell built by ABB can be simulated on RobotStudio, ABB’s offline robot programming software. Using ABB’s dedicated PowerPac welding software add-in, Katcon can create complex robot paths for its FlexArcs in a short amount of time. Using RobotStudio, the company can inspect every aspect of the welding process virtually before the actual setup is made without impacting on the real production process. Possible issues such as collisions between the welding torches and jigs will be highlighted in the working simulation, enabling them to be rectified if needed.
“RobotStudio gives Katcon another avenue to maximize their investment in the FlexArc welding cell. By simulating a new project, Katcon can estimate production costs, cycle times and understand how many operators or how many welding cells are needed for the project. By connecting RobotStudio to engineering programs such as AutoCAD, ABB can also import the design of jigs and check the entire welding set up before the start of production,” says Robert Mrozik – Sales Specialist/ ABB.
“Each new design of jigs and any new produced parts can be uploaded to Robot Studio for the customer to check for any outstanding issues. We can check reachability for welding process, torch positioner and jig construction. We can easily check for collisions between the welding torch and any parts of jigs. Overall, this solution reduces production costs for welding jigs, which ultimately means savings for Katcon’s customers too.”
A key advantage for Katcon with the standardized FlexArc welding cell design was that its employees did not have to undergo extensive training before they began operating the machines. Moreover, the intuitive FlexPendant graphical user interface makes it easy for operators to get an overview of the entire status of the cell and enables them to communicate effectively with all the functions within the cell and access information regarding its performance.
ABB is able to design cells specifically to the needs of the customer. With the ABB training center and Warsaw headquarters situated close to the Katcon factory, ABB can provide rapid after sales support and services to the company.
The new FANUC cobot at Emerson unloads finished parts at the Nakamura WTS-150 and removes residual pieces from the bar feeder - around the clock © FANUC
With around 80 employees, Emerson Professional Tools has been developing, manufacturing and assembling pressing tools and pressing jaws for pressing fittings with various diameters - from 12 mm to 108 mm (4 inches) - at its Swiss site in Sissach for over 35 years. These are primarily used for connecting sanitary, water and gas pipes in buildings.
The company's high-quality products are based on highly qualified employees and modern machines and systems. These include a 5-axis CNC lathe Nakamura WTS-150, whose existing portal automation solution failed at the beginning of October 2020 due to a defect. Plant Director Stefan Rüdisühli therefore had to quickly find a solution together with the machine operators.
He explains: "A repair would have been very time-consuming and expensive, so we preferred a new automation system." The challenges were manifold. The solution had to be reliable, easy to install, reasonably priced and available as quickly as possible. "In addition, we had to be economical in terms of space," adds Stefan Rüdisühli, who is responsible for the management and further development of the site and thus also for production.
In his search for a suitable supplier, Stefan Rüdisühli contacted the Swiss FANUC subsidiary, among others. The reason for this was, on the one hand, decades of good experience with FANUC controllers and, on the other hand, two FANUC robots that have been reliably in use since 2019 and 2020. Although Emerson is entering new territory with the Cobot CRX-10iA/L, "the solution has convinced us in every respect, and we can't imagine a better automation for this CNC lathe, even from today's perspective. It runs perfectly and reliably. We are also very satisfied with regard to all other challenges."
As a collaborative robot, the FANUC CRX-10iA/L does not need any elaborate safety devices, which ultimately has a positive effect on its footprint. The decisive factor here is that it fully complies with the safety standards according to ISO 10218-1. Another important feature for safe handling are its sensitive sensors, which trigger an immediate safety stop when a human body is touched. The anti-trap protection and the soft rubber skin with which the CRX is partially covered also ensure that the machine operators always feel safe and work without fear in close contact with their robot colleagues.
The tasks of the FANUC cobot are clearly defined at Emerson. It unloads finished parts from the Nakamura WTS-150 and removes remnants from the bar feeder. That is exactly what it does around the clock. Even an unmanned ghost shift is now possible with it. Thanks to the high process stability, Stefan Rüdisühli has been able to increase the daily availability of the lathe by to up to 96 percent. A value that delights the plant manager and his employees: "We are currently producing cylinder heads for our new generation of press tools on this machine. Our requirements are enormously high. Accordingly, the high availability of the entire system is currently helping us a lot."
The installation of the CRX-10iA/L as well as the initial programming for the tasks to be performed were carried out by experienced technicians from Wick AG - supported by Emerson machine operators. The system house from Küssnacht in Switzerland has been developing automation solutions for small and medium-sized companies for around 20 years. Robotics in general and the cooperation with FANUC Switzerland GmbH in particular play an important role for Wick. Guido Lüönd, CTO of Wick AG and member of the management board, emphasises: "We have already been able to gain some experience in dealing with collaborative robots in recent years. Not least because of this, the commissioning of the FANUC Cobot CRX-10iA/L at Emerson worked smoothly throughout.“
Lüönd is particularly enthusiastic about the ease of installation of the new CRX series: "Thanks to its lightweight, compact design, the FANUC CRX-10iA/L can be easily integrated into any work area or existing systems. We don't need a crane or any other lifting device for this." This is matched by the new, particularly compact R-30iB Mini Plus control system. The automation expert is also impressed by the convenient programming options: "The FANUC CRX-10iA/L allows Manual Guided Teaching. This means that the robot can be easily guided by hand to the desired positions, which can be saved on the tablet using the drag & drop function. This way, a new application is programmed in just a few minutes.“
Emerson is already planning further automation in which robots from FANUC are to play a leading role, because of the great progress that’s been made already.
Safe interaction with its environment - Stäubli AGVs offer a seamless integration on the factory floor @ Stäubli
Before construction on its new coating plant started, the entire project was already planned with the automation expert and subsequently implemented.
In its Labels division, HERMA manufactures self-adhesive paper and film laminates using state-of-the-art coating technology and a high level of innovation. A high degree of automation is crucial for optimum material flow. Among other things, a driverless transport system for the newly built coating hall had to meet this criterion.
Weighing up to 4.5 tons, 24 kilometers long and 2 meters wide, the paper and film rolls are real heavyweights. This makes it all the more important to transport them to their destination automatically and precisely without additional sensors. From goods receipt via a high-bay warehouse to processing and subsequent shipping, the AGVs are loaded and unloaded several times. In addition to the smooth cooperation of the different machines, this requires a high positioning accuracy of 2 millimeters.
The system also had to be easily adaptable to new routes, machine locations and structural changes in the future. Stäubli WFT has realized this with a fleet of several AGVs, spread over two floors. The system can be flexibly expanded.
The intensive project was as challenging as it was successful. The modular AGVs with their patented drive technology consistently meet HERMA's specific requirements. For example, the dynamic control of the AGVs is carried out via a master computer, which allows the operator to react to changes quickly and easily. The omnidirectional vehicles fit seamlessly into the local conditions as well as the infrastructure and communicate with a variety of relevant interfaces – from the conveyor system to the warehouse management system.
Each delivery and pick-up station is approached fully automatically and precisely. For HERMA, all this means continuous material flow in three-shift operation.
As a result of implementing the AGVs from Stäubli WFT, downtimes have been significantly reduced and productivity increased. However, this is not the only reason the project was successful, according to Frank Baude, Logistics Manager at HERMA:
"In addition to the continuous flow of goods and the noticeable increase in productivity we have experienced thanks to the AGVs, I would like to highlight the great collaboration. The pragmatism, the technical know-how, and the drive of Stäubli WFT to always achieve the best for us, that will remain in my memory for a long time."
Due to the inspiring and successful experience of the project, HERMA is currently considering using fully automatic vehicles from Stäubli WFT in the outdoor area between the individual parts of the building as well. The first concepts for this are already on the table.
"Right from the start, we believed that it was possible to combine tradition and innovation, turning TorArt into an artistic workshop that utilises the most innovative digital techniques, combining a deep respect for traditional hand workmanship with a passion for innovation, through the use of the most cutting-edge technologies out there." These are the words of the company founders Filippo Tincolini and Giacomo Massari, who go on to say "Our job is to make the work of artists a reality, and to meet the requirements of world-famous masters such as Barry x Ball, Jeff Koons, Francesco Vezzoli, Vanessa Beecroft, Giuseppe Penone, Maurizio Cattelan, Zaha Hadid and Jimmie Durham, to name just a few, as well as to succeed in implementing digital archaeology projects and recovering artistic heritage, such as the New Monumental Arch of Palmyra, and works by Canova, Michelangelo and Thorvaldsen - these projects have led to improvements in the performance of the robots used, and this in turn has led to the birth of ROBOTOR".
Today, the mission of ROBOTOR is to deliver an automated technological solution to people which serves to simplify the production process, delegating stone machining operations to the robot. We are witnessing the start of a new era - not just of chisels and dust, but also of scanning and point clouds, where ROBOTOR technology adds value to the process, preventing the artist from having to carry out the most arduous, risky and dangerous work.
"Our strengths lie in our ability to transform the vision of artists with extreme precision and accuracy, whilst drastically reducing production times" explains Giacomo, continuing "Over the years, there are two particular moments in which our work has gained widespread visibility - the first of these was back in 2016, when we created a replica of the Monumental Arch of Palmyra, which was destroyed by ISIS. Our technology enabled us to reconstruct this precious ornamental archway in just 5 weeks, and from a three-dimensional scan, we were able to recreate the arch in a scale of 1:3 using 20 tons of machined marble. This work came to represent a symbol of the strength of technology at the service of mankind, standing against the barbarity and injustice of war. The arch has travelled around the world - from Trafalgar Square in London to New York and Geneva; it has proved to be of great importance for us.
The other key moment occurred this year, when the New York Times wrote about us, dedicating the front page of the print version of the paper and an online article to the company, in which it raised the question of the real authorship of works of art - in other words, whether robots can sculpt better than artists, such as Michelangelo, or whether contemporary artists actually put their own stamp on these creations. This discussion addresses a fundamental theme, and reinforces rather than undermines the importance of technology in our vocation at this point in time."
"ROBOTOR is the end result of an extraordinary idea: delegating the task of managing the various phases of machining carried out by the robot to artificial intelligence!" comments Filippo, as he watches the robot equipped with the HSD ES748 electrospindle masterfully working on a statue of a little girl "What you see here is without doubt the highest-performance system we have ever made, Both One, which combines power and precision. It is designed to support heavy weights - the work table can sustain up to 35 tonnes - and can be used to work on sculptures of up to 3.5 metres high.
The system consists of a mechanical arm which uses a range of HSD electrospindles of various sizes and capacities, and features an automatic tool change function, suitable for the CNC milling of various materials. The arm takes full advantage of the areas of movement whilst occupying the smallest possible space, and is equipped with a number of special devices designed to work in extreme conditions. The arm is mounted on a multifunctional base inspired by lunar modules; here, the spaces and the various electrical and hydraulic components are organised and optimised in a safe and highly protected manner. The software remains the beating heart of our systems; in this case, it is fully dedicated to sculpting and to extremely complex projects that even a very experienced programmer would struggle to create. This type of artificial intelligence is based in the cloud - that is, it is not local, but online - and it fully manages the instructions that the system needs in order to create the sculpture. With regard to these instructions, we give it the block, the model and the tools, and this application generates the safest pathways, simulates these and then sends them to the control panel, in order to be executed by the robot in complete autonomy; experience in the configuration of anthropomorphic robots is not required."
“For this project”, confirms Filippo, “we are working with two strategic partners, Kuka and HSD - we consider them to be leaders in their sector, Kuka in anthropomorphic robots and HSD in electrospindles. Bringing these two families together gives us peace of mind with regard to the product, the support and the service, as well as in terms of the development of the new robots we plan to bring to market.”
“Our goal – Giacomo Massari reiterates – is to push the boundaries! To push the boundaries in order to ensure that there are no limitations for the artist and to use technology to enable seemingly impossible feats to be achieved - to go above and beyond to make our solutions accessible to everyone” concludes Giacomo "The robot-sculptor is already a reality, but the robot-artist will never exist!".
YuMi picks and places components (copyright: ABB Robotics)
To assemble a specific component of blood separation centrifuges, called "stem", LivaNova relied on the experience of system integrator Sintech and the skills of ABB YuMi cobot. "After automating a part of the process with articulated robots two years ago," said Claudio Sinico, Sales Manager, Sintech, "automation has now been extended to the stem, involving assembling, testing and solvent dispensing stations that operate in automatic and synchronized steps."
LivaNova has factories in all continents, including a plant in the biomedical district of Mirandola, an Italian tow in Emilia-Romagna. The Mirandola site is a global excellence for cardiac surgery devices, mainly oxygenators, filters, heat exchangers and blood separation centrifuges. Each day, LivaNova ship their products to hospitals across Europe and the world. Approximately 2,600 centrifuges are delivered every day for immediate use to operating theaters for critical heart surgery operations, mostly open heart surgery with extracorporeal circulation: no compromise on device quality is acceptable!
The dual-arm version of YuMi has increased process efficiency, helping automate a semi-manual process and improving safety for operator who no longer have to dispense solvents. According to LivaNova engineers (the project involved Giulia Sarti, Davide Di Mari, Franko Masllavika and Daniele Roveri of the industrial engineering team), the robot, certified for cleanroom operation, is very easy to program compared to conventional articulated robots, thanks to an easier interface and straightforward point picking with no specialized skills. The customer mostly appreciates the easy process to access and correct picking, placing and positioning points, as well as the light weight and the easy handling that other robots cannot offer. Finally, with RobotStudio, Sintech's engineers can program the entire working cycle of robot-assisted islands virtually, simulating all movements and checking the feasibility and cycle time of each application.
LivaNova is a global medical technology company created in 2015 from a merger between Sorin Group, listed on the Milan Stock Exchange, and US-based Cyberonics. Today the group generates approximately one billion dollar revenues with factories in all continents. Among these, the plant in the biomedical district of Mirandola, an Italian tow in Emilia-Romagna, is a global excellence for cardiac surgery devices, mainly oxygenators, filters, heat exchangers and blood separation centrifuges, used in operating theaters for cardiac surgery.
RG2-FT gripper from OnRobot is mounted on a collaborating robot arm (copyright: OnRobot)
Even back then, Otto Schott was considered a pioneer in the science of glass, and SCHOTT AG, the company he founded, continues to break new technological ground today. In the glass laboratory of its Mainz research center, the international technology group uses a collaborative application for quality testing - and in doing so relieves the laboratory staff of more demanding tasks. This gives SCHOTT more capacity for development projects and enables it to efficiently handle the growing volume of samples. This is made possible by a gripper from OnRobot. Thanks to integrated sensors in its fingertips, the RG2-FT can handle individually shaped glass samples and operate highly sensitive measuring instruments.
Whether in aerospace, medical technology or the automotive industry: The diverse products of SCHOTT AG are used in almost all areas of life. The technology group with its focus on glass and glass ceramics has been producing new innovations for 130 years. At that time, company founder Otto Schott initiated the special glass industry as a separate branch of industry by using novel manufacturing processes to develop glasses with precisely defined properties for the first time. Since then, Schott has considerably expanded the range of applications for the material over the years.
In keeping with its founding idea, today's SCHOTT AG is also always operating at the limits of what is possible and is continuously expanding this through technological progress. The SCHOTT Research Center in Mainz plays a key role in this process. In the glass laboratory there, employees test glass samples for their physical properties. Through their measurements, they generate data that are incorporated into the company's numerous research projects. On the other hand, they regularly test samples from production.
"The material that is processed has to meet very specific specifications to ensure that a flawless product is ultimately created," explains Dr. Axel Engel, Senior Manager Physical Analytics at SCHOTT. "This ensures high product quality and helps to reduce waste." For example, when it comes to ceramic glass for hotplates or glass for fireplace doors, it must not be allowed to deform under any circumstances when exposed to heat. "Quality control is therefore very important for the entire manufacturing process." Today, SCHOTT automates part of this step with the help of a collaborative application using a gripper from OnRobot.
The impetus for this was a sharp increase in the number of samples that have to be tested for research purposes. "In the last three years, the volume of samples here in the laboratory has increased by about 30 percent," reports Dr. Engel. This posed several challenges for the manager and his team: SCHOTT needed more capacity to test so many samples in the time available. However, additional measuring equipment and personnel would only have limited space in the limited laboratory space. In addition, it took the employees a lot of time to load the measuring device. A measurement takes between three and 15 minutes, after which the employees have to interrupt other activities in order to insert a new sample. This is where the idea of automating the measuring process first came up.
"We put a lot of time and effort into selecting a suitable automation solution," recalls Dr. Engel. "The solution had to be space-saving and be able to work right next to the laboratory technicians. A conventional industrial robot was out of the question: it would have needed an additional protective enclosure, and there is no room for that". There was also another difficulty: the measuring device, a so-called transmission spectrometer that records the optical properties of the glass, is extremely sensitive. Inserting the samples in such a way that the expensive device is not damaged requires great sensitivity. "After looking at solutions from various manufacturers, we finally found what we were looking for in OnRobot," reports Dr. Engel.
SCHOTT decided on an application in which an RG2-FT gripper from OnRobot is mounted on a collaborating robot arm. The special thing about the electric two-finger gripper is that both force/torque sensors and optical sensors are located in its fingertips. These enable him to "think along": The sensors feed their process data back to the robot arm, which adjusts its course accordingly. This enables the gripper to precisely meter the force applied to the arm. This gives the application as a whole the necessary sensitivity to load the spectrometer with millimeter precision.
"With the help of its sensor technology, the gripper is able to identify the position of objects and grip them in the center without knowing the exact parameters in advance," explains Florian Grabowski, Project Engineer at SCHOTT. "In this way, it can also efficiently support the measurement process." For this purpose, the glass samples are lined up next to the application in a holding fixture, the so-called tray. On their sides are barcodes that the RG2-FT uses to identify which sample it should pick up next. The RG2-FT is coupled with the software of the measuring instrument for this purpose. Thus, it knows which sample is to be measured next. He picks up the corresponding sample and places it in the spectrometer, where it is clamped in a pneumatic cylinder. Then the measurement begins. The robot then automatically removes the sample and places it back in the tray.
Physics laboratory technician Nicole Mück used to operate the spectrometer manually. Now she benefits directly from the new application. "I have more time for documentation tasks, for example elaborate test reports," says Mück. "I can use the spectrometer more for more complex measurements involving test objects of different shapes and sizes - this is more complicated and requires me to process the samples myself. The application can continuously load the measuring device. This means it can work overnight and on weekends without a break. As a result, the robot has already handled a large part of the sample volume when Ms. Mück and her colleagues start their working day.
SCHOTT worked closely with OnRobot and the local system integrator Fichtner to integrate the gripper and robot arm, as project engineer Grabowski reports: "We were in active communication with both OnRobot and Fictner during implementation. We also developed special fingertips to optimally adapt the application to our requirements. These consist of aluminum and are coated with foam rubber. The background: The glass samples are handmade at SCHOTT so that each sample is individual. "With the help of its sensor technology and the adapted fingertips, the RG2-FT can still grip the sample glasses perfectly," Grabowski explains.
The robot arm and gripper can be controlled via an intuitive user interface that the team accesses via a tablet. "The interface is clearly structured so that it is easy to find your way around," explains Grabowski. "Even users without special programming skills can easily assign tasks to the robot".
Dr. Engel is satisfied with the pilot project: "With the application we can work much more efficiently and relieve our employees," he sums up. Thanks to the rapid integration and smooth processes, the application also promises a rapid ROI: "We expect the purchase to pay for itself within five to six months".
Soon, SCHOTT also wants to use collaborative applications in other areas of its internal value chain. One conceivable area would be glass processing, for example, where many process steps, such as drilling, milling or grinding, are currently still done by hand. With collaborative applications, such tasks can already be automated cost-effectively today. In this way, SCHOTT is making itself fit for the future and focusing on always be one step ahead of the status quo.
A staggering 640,000 tons of fishing nets are dumped into the sea every year. An additional 150 million tonnes of garbage floats in the world’s oceans.
In a pioneering project, Swedish sustainable design house Sculptur is turning the discarded nets and plastic waste into furniture using a specially adapted robot from ABB. The industrial robot functions as an advanced 3D-printer.
Because the robot can apply the injection molding of the plastics from any angle, it is far superior to conventional 3D-printers and helps save around 50 percent of the required base materials. ABB's simulation and offline programming software RobotStudio, offering a complete digital twin of physical assets, and a newly developed add-on for 3D-printing, ensure that the printing robot can be programed in just a few minutes. A complete designer piece can be manufactured in less than two hours.
Sculptur and ABB share the same philosophy that by using recycled products and cutting-edge technology they can together make the world a better, more sustainable place.

290 concrete panels form the facade of the BESIX 3D studio in Dubai, part of the Belgian BESIX Group. 290 panels, each of which was printed in around ten minutes with the aid of a KUKA robot and then simply mounted on the building on site. It was the construction group’s first groundbreaking project and is currently considered the largest 3D-printed concrete facade in the world.
Fast, environmentally friendly and safe: 3D printing with concrete is set to revolutionize traditional construction methods. The additive manufacturing process avoids waste and delivers customized solutions or even entire series in just a few hours. Construction companies around the world are currently working to find the best method for 3D printing. One of them is the BESIX Group, headquartered in Brussels. Founded in 1909, the company set up a 3D studio in Dubai for this purpose in December 2018 and installed a robot from the KR QUANTEC family for carrying out the printing.
“For us, it was particularly important to find a reliable partner at the start of the project who was prepared to think in new dimensions with regard to printing. We found this partner in KUKA and can now implement our project automatically,” says Benoît Meulewaeter, Senior Project Manager for Design and head of the BESIX 3D team. Together with automation specialist KUKA from Augsburg, the company developed its robot application for 3D printing with concrete as the material. All the shaped elements required by the customer are modeled in advance using 3D software.
“There are no limits in additive manufacturing – even for complex requirements. 3D printing enables us to individually produce any customized shape,” explains Meulewaeter. Once the model is ready, the software transfers the data to the KR QUANTEC, which has a nozzle on its articulated arm for 3D printing. The robot then prints sculptures, facade elements and other components for buildings layer by layer according to the specifications. Fast and effective. In this way, a two-meter high column is produced in less than an hour.
The customer also has flexibility when it comes to color: colorfast pigments can be mixed into the concrete material before printing to achieve the customer’s desired color. The robot not only carries out its work quickly, but also does so in near silence and in an environmentally friendly manner. The liquid concrete material is converted 1:1 into the end product, so that no waste is produced in the process. Use of the KR QUANTEC also reduces CO2 emissions since the robot can print the desired prefabricated concrete element directly at the construction site and it does not have to be specially transported.
Benoît Meulewaeter notes: “Through 3D printing using concrete, we are resolutely pursuing our corporate goal of offering efficient and environmentally friendly solutions.” KUKA provides support here as well. Alois Buchstab, head of the KUKA team overseeing the 3D project, says: “We are delighted that the BESIX Group has chosen KUKA as a cooperation partner. Thanks to our energy-efficient robotic solutions and expertise, we are living up to our responsibility to create a sustainable future.”
The BESIX 3D team is currently working with other partners to develop environmentally friendly concrete mixtures for additive manufacturing. These can be used in areas such as the construction of breakwaters. The company is also considering having the KUKA robot print directly on site in order to avoid transport costs. “We are highly satisfied with our collaboration and certainly will be able to move forward with many more projects with KUKA in the near future,” says Benoît Meulewaeter. The company is considering expanding its production facility in Dubai or even opening similar studios in Belgium or the Netherlands.
The TX200L HE transfers the round cheese to the maintenance system's conveyor belt. © Stäubli
The Leupolz farm cheese dairy is located near Wangen, just north of Lake Constance, in a truly idyllic setting surrounded by forests, pastures and meadows. Founded in 1960, the cooperative employs 25 people and obtains its milk from around 170 suppliers. It processes around 45 million liters per year, equivalent to about 125,000 liters per day. Among the dairy’s specialties are cheese “wheels” weighing approximately 80 kilos, some 6,000 of which leave the farm every year, with around 10% qualifying for the Demeter organic label.
The correct maintenance and care of these huge cheeses is a laborious business. Achim Baumgärtner, Executive Assistant at Leupolz, explains: “Each cheese wheel has to be attended to about three times a week to ensure optimal quality. With an average maturation period of four months, the cheeses have to be washed, brushed and salted between 40 and 50 times, which is potentially costly in terms of labor and expenditure.”
The management team at Leupolz was looking for a solution that would be as efficient as it was economical, so that they could offer this natural product at a competitive price despite the intensive effort that goes into its storage and care. The vision of a fully automated system began to take shape…
To realize this vision, they brought in Lemmermeyer, a plant manufacturer based in the Bavarian town of Deiningen. The company has extensive experience in the field of stainless steel plant construction and has built an especially strong reputation for itself in the food sector.
The stainless steel cheese maintenance system, which entered operation in 2019, is a prime example of Lemmermeyer’s design expertise. Attention was paid to compliance with stringent hygiene standards, avoidance of dead spaces, and the right choice of robot for handling the cheese wheels – in this case, the large six-axis Stäubli TX200L HE.
“If we had used classic linear axes for the handling processes within the plant, we would have come up against a major hygiene obstacle,” says Manfred Görthofer, Head of Project Management at Lemmermeyer. “Condensation buildup and lubricant contamination via the joints of the axes could not have been avoided, and this is of course problematic when processing unwrapped foodstuffs. That’s why we are increasingly moving towards the use of encapsulated Stäubli robots with their superior hygiene design for such processes.”
The Leupolz setup clearly demonstrates that the robot-assisted cheese maintenance system not only complies with strict hygiene standards, but is also impressive in terms of performance, with around 80 cheese wheels passing through the system in the space of an hour. The task of the TX200L HE (HE = Humid Environment) is to load and unload racks with either four or eight shelves on which the cheese wheels are stored. A forklift collects the racks from the maturation chamber, delivers them to the processing area, and returns them afterwards.
The six-axis robot is equipped with a special gripper that resembles the prongs of a forklift. It uses this to pick up the wooden board on which the cheese rests and places it on the system’s conveyor belt. The next step is to separate the board from its cheese wheel. The board is then cleaned, while the cheese is washed, brushed, sprayed with salt and dried with a blower. The final step is to place the cheese wheel back on its board and move it to a defined transfer position on the conveyor belt. Here, the TX200L HE picks it up and places the board together with the cheese wheel back in the correct compartment of the rack.
To ensure that the six-axis machine can approach all stations without hindrance, it is mounted on a base unit. The TX200L has a reach of just under 2.6 meters, and with a total weight of 100 kilograms to be handled (80-kg cheese wheel, 5-kg wooden board and 15-kg gripper), axis 6 operates at its full payload limit.
Even when the robot is lifting and carrying its maximum payload, it can still easily cope in continuous operation. As Achim Baumgärtner says, “Our TX200L HE has been running absolutely trouble-free since commissioning. The same applies to the entire system. We have not experienced any failures here, and even our daily cleaning procedures are incapable of harming the system or the robot.”
Stäubli’s HE robots have indeed been designed to endure even the toughest cleaning procedures with aqueous media in the 2pH - 12pH range. These robots even withstand spraying by a high-pressure water jet without any problems. This means they can be operated without an additional protective coating and cleaned quickly and thoroughly. Plus, the HE versions are just as capable as the standard robots, which puts them among the fastest on the global market, even when operating with food-grade oil.
The use of robots has also resulted in impressive savings. “In the past, we needed three people to attend to the cheese. Today, it’s done by ‘half’ an employee,” says Achim Baumgärtner. “Of course, this saves on labor costs and, much more importantly, we can relieve our staff of weekend working, deploy them where they are needed more urgently, and do not have to constantly ask them to work overtime. The shop floor atmosphere and the workload have improved significantly due to the higher degree of automation.”
Another important aspect concerns the care and maintenance of the cheese wheels themselves. The enormous capacity of the robotic system makes it possible to significantly shorten the washing intervals and thereby enhance overall quality. Achim Baumgärtner: “Thanks to the robot, we can now attend to the wheels up to three times a week. In the past, we had to get by on just once or twice. The more intensive care has a positive effect on the quality of the cheese, and we have a higher product yield. This works to the benefit of the end consumer, too. Our Allgäuer Emmentaler has never tasted better!”

Mega dimensions: Two 8MW nacelles present an impressive sight: The frames bearing components weighing many tonsnes are maneuvered by AGV. © Siemens Gamesa
The manufacture of wind turbines for offshore installations is on a completely different scale from standard mass production. The rotor blades of the 8MW SG 8.0-167 DD turbines that Siemens Gamesa builds for offshore wind farms are 81.4 meters in length. The turbine’s total height is 167 meters (10 meters higher than Cologne Cathedral) and the nacelles weigh around 350 tons. These machines for sustainable energy production are in demand all over the world. The nacelles are built at the Cuxhaven plant, which was newly constructed in 2018 for this very task. The rotor blades come from other sister plants of the Siemens Gamesa Group.
Just as impressive as the dimensions of the turbines are the workflow and capacity of the plant in Cuxhaven. More than 250 nacelles are produced each year and loaded directly onto specially built transporter ships. In other words, the 600-strong workforce builds a complete wind turbine nacelle every day. This is flow production on a mega scale.
The three main components – the hub, the two-story “backend” machine house, and the generator itself – are assembled on three parallel production lines. The magnets that go into the generator are also manufactured at the Cuxhaven plant, with a similarly high degree of vertical integration. These three massive components are brought together to form the complete nacelle, which is then comprehensively tested at an inspection station.
Assembly takes place in cycles at individual stations, and the components, which weigh many tons, are placed on frames that allow them to be transported from station to station. This is mainly done by crane, but in order to ensure maximum flexibility, driverless heavy-duty transport systems (AGVs) from Stäubli WFT are also used for transport around the factory. The AGVs maneuver themselves into position underneath the frames, lift them up, and move them to the next assembly station.
Three heavy-duty platform AGVs from the Stäubli WFT range with a load capacity of 200 tons are in service. They get around with the help of eight omnidirectional drive units – a patented in-house development by Stäubli WFT. Eight fixed rollers provide support when transporting the load.
A human operator moves the 8.00 x 2.62-meter platform under the frame by remote control and raises the platform by 200 mm at the push of a button. At a maximum speed of 1.2 km/h (2.1 km/h when unloaded), the operator transfers the component to the next assembly station. This ensures smooth travel and is gentle on tires as well as floors – thanks to the patented Stäubli WFT drive technology, rotary movements cause minimal abrasion.
RFID tags installed in the floor create the right conditions for semi-automatic operation. The AGVs then move between pre-programmed positions. And this is only the first stage in the integration of heavy-duty AGVs into automated material flow concepts. The control system also allows integration into Industry 4.0 environments and warehouse management systems. In addition, Stäubli WFT can provide AGV data for process optimization.
The combination of transport by crane and/or AGV has been adding value since the start of production in Cuxhaven. Ample proof of its unique advantages was provided during the first model changeover. “Production started with our 7MW offshore turbines,” says Nils Schattenmann, who is in charge of rolling equipment at the plant. “Later, and without any interruption to production, we switched to the current, much larger 8MW turbines. The time and effort involved was minimal, with the AGVs only having to be reprogrammed.”
Senior management is also completely satisfied with the vehicles supplied by Stäubli WFT in more conventional operations. “The AGVs work reliably and with high precision. Because these vehicles are an integral part of the internal material flow, we cannot afford any downtime here,” Schattenmann adds.
The reliability factor applies all the more to the fourth heavy-duty AGV supplied by Stäubli WFT. Its load-bearing capacity of 450 tons is more than twice that of its predecessor, and with a platform dimension of 10.5 x 3.02 meters, it is also significantly larger. Here, 16 drive units, supported by 19 fixed castors, ensure mobility.
This AGV is essentially reserved for the final process step – the transport of the finished nacelles to the test stand. It therefore also has a fixed role in the mega-scale flow production.
The vehicle can lift and transport more than eleven times its own tare weight of around 40 tons, bringing a total weight of more than 400 tons to the weigh station. There are very few AGV manufacturers in the world that can compete in this payload class, but Stäubli WFT goes one better: For loads of 500 tons and over, multiple vehicles can be hitched together. AGV control systems are basically set up for this.
Siemens Gamesa plans to purchase a fifth heavy-duty AGV from Stäubli WFT for the Cuxhaven plant in the near future. “We are currently setting up production for the next generation of offshore wind turbines, which will be significantly larger and also deliver an enhanced 11 MW of power,” says Schattenmann. In concrete terms, this means that the SG 11.0-200 DD will have a rotor diameter of an incredible 200 meters, and the nacelles will weigh a third more. They will also be equipped with a helicopter landing pad.
Flexibility again played a central role in planning the in-plant heavy-load material flow. For this reason, the system designers at Siemens Gamesa opted for a second model of the existing 450-ton platform rather than a single, even larger AGV. As Schattenmann explains, “We will then transport the finished nacelles of the new turbines from final assembly to the test stand on the two 450-ton vehicles operating in tandem. The fact that Stäubli WFT has the technical expertise to enable synchronous operation of vehicles of this size is a great advantage for us. It allows us to use the vehicles individually or paired up for maximum flexibility.”

The robotic picking system helps improve the efficiency of sorting at the facilities and ensures meeting higher purity standards. To date, the limited availability of scalable recognition technologies has pushed the waste management industry towards a reliance on manual waste pickers to identify and extract high value materials. Together, FANUC and Recycleye have addressed this issue by delivering intelligent automation to the industry, combining Recycleye’s validated AI computer vision technology with FANUC’s 60+ years of experience in automation.
Recycleye Robotics performs the physical tasks of identifying, picking and placing material, at a rate of 55 successful picks per minute. The novel solution automates current manual operations and enables facilities to double their total throughput. FANUC’s team of expert automation engineers designed Recycleye Robotics to weigh 75 percent less than any existing robotic waste picker currently in the market. The plug-and-play installation eliminates traditional expensive retrofit costs.
Recycleye Robotics is powered by Recycleye Vision, an AI vision system, which has been deployed across the UK and French markets, exceeding human vision in identifying and classifying all items on waste streams – by material, object and even brand. Recycleye Vision works to constantly train and learn new object detection, enabling for the robotic waste picking system to adapt to changing waste composition without any need for manual upgrades.
For instance, the retail, manufacturing and public sectors are increasingly turning to innovative robotics, sensors and AI (artificial intelligence) technologies to ease the pressure on employees, accelerate processes and improve compliance with hygiene requirements. The Technical University of Darmstadt reports that the acceptance of robots has increased significantly in recent months.
Companies wanting to benefit from this trend need to act quickly and to form partnerships with organisations that have expertise in these areas. The power of such co-operation has been illustrated recently by the work carried out by German medical technology company, Senova, in conjunction with robotics experts from OMRON and mechanical engineering specialists from Kraus Maschinenbau GmbH. Senova is a leading developer and manufacturer of rapid test systems for marking biomarkers, viruses and microorganisms.
Working closely together over the past six months, the three companies have developed and built production machines that include smart robotics. These have automated, accelerated and improved the very time-consuming manual production of coronavirus antibody rapid tests. This met a vital need, as the increased testing of more and more people for the virus meant that the production of kits had to be hugely ramped up. At the same time, there needed to be more interlinked production and packaging.
Senova specialises in lateral flow assay (LFA) technology. Some 30 employees are involved in the research, development, production, sales, logistics, quality management and assurance. Senova’s most recent - and most popular - product is a rapid COVID-19 antibody test. This shows within ten minutes whether someone has already been infected with the virus.
An international research team, including the Jena Leibniz Institute for Photonic Technologies (Leibniz-IPHT), developed the test. It has been available since spring 2020. A blood sample shows whether someone is currently infected with the virus or is already immune. There are two types of antibodies. The IgM antibodies are found in the blood a few days after infection, whilst IgG antibodies are only formed during the course of the infection. They often remain detectable for months and indicate an existing immunity.
This enables people including caregivers, nurses or doctors to find out whether they are immune to the virus. The research team completed the tests together with Chinese partners and a medical device distributor, Servoprax, and confirmed their effectiveness. As a result, Senova brought the first coronavirus antibody rapid test to the market in record time.
Due to the worldwide demand for the new tests, Senova needs to produce them in ever-increasing quantities. The previous manual production and packaging of the test kits was unable to keep up with the thousands of order requests. The company therefore needed a more flexible, faster and more reliable way of manufacturing and packaging the test kits – all within a very tight timescale. A machine would ease the pressure on employees by streamlining and combining the various work steps (such as cutting the test strips and packaging) much more efficiently. The concept and implementation needed to be carried out particularly quickly to meet the demand - and to help contain the spread of the virus.
Joachim Kraus, Managing Director of Kraus Maschinenbau GmbH, comments on the start of the project: “Senova asked how the feeding of the packaging pouches could be automated in the best possible way. In the following discussions, we worked with the customer to develop an overall concept for feeding and packaging the test cassettes for the rapid antibody test.”
This new concept was rapidly approved. But that’s not all: following the design review, the co-operation between the two companies was expanded further. The precise cutting of the test strips and the subsequent transfer of the section and the insertion of the cut into the test cassette are now performed by machines from Kraus Maschinenbau. These are complemented by robotics and technology from OMRON, a partner of Kraus for 11 years.
Handling the blanks with a size of 3.5 to 5.0mm proved to be a particular challenge, but this was solved after a few adjustments. With the help of the new machine, 30 to 45 rapid coronavirus tests can now be cut and packaged per minute. As the demand is so great, the capacity must be continuously increased, so more machines are now planned. Production currently runs for six days a week, from 7am to 10pm.
The tests (which look similar to a pregnancy test) are produced using machines from Kraus, along with OMRON’s eCobra600 robots, Quattro 650 H four-axis parallel robots, OMRON TM5-700 cobots, PLC controls, drives and sensors. Due to the increased production volume, OMRON has already delivered additional eCobra600 Pros and integrated them into the production line. These robots are particularly reliable, flexible and powerful.
The SCARA robots are ideal for the precise processing, assembly and material handling used in medical technology. The four-axis robot has a range of up to 800mm and can be easily adapted for different applications, such as test production. The eCobra technology also offers high repeatability and a payload of up to 5.5kg. The amplifiers and controllers built into the robot reduce the number of cables needed. The overhead mounting configuration enables the efficient use of space, even in clean rooms, which are so essential in the medical technology environment.
The control and drive of the cutting and packaging machines also comes from OMRON, and is built into the production lines of Kraus Maschinenbau. Further components of the flexible COVID-19 test kit production include the Quattro 650 H four-axis parallel robots. These can be controlled by Ethernet, using the familiar programming language (IEC 61131-3) of the NX / NJ machine controllers. The four-axis arm distributes the load evenly to the robot, which supports fast and high-precision transport and assembly. The Quattro robots are designed for high payloads and multi-hand applications: several parts can be picked up at the same time. This also accelerates the production of the coronavirus test.
But that‘s not all: another technology used in Senova‘s production line is the OMRON TM5-700 cobot. This is specially designed to work with people and machines. It can be easily transported and has an integrated image processing system, which enables quick start-ups and product changes. Due to the intuitive software, the cobot can be taught different tasks. For example, it relieves employees of recurring tasks involving test cutting and packaging and helps to increase productivity. The integrated vision camera and lighting technology enables objects to be detected precisely in a wide field of view. This system helps Senova to increase reliability, consistency and precision (e.g. in pick-and-place processes). Other functions available include pattern and colour recognition and barcode reading.
But how are the test strips cut and packaged? First, the preliminary products are fed to the line. They are then separated, positioned and placed in a servo linear unit. The product can then be positioned under the cutting knife and cut precisely. The robot inserts the blank into the plastic test cassette and assembles the front and back. The machine for packaging the rapid antibody tests then takes over the test cassettes.
The pre-assembled packaging pouches are separated by a JoKer friction feeder and dispensed onto the packaging machine. A labeler applies the labels with the relevant product data to the pouch. Another robot takes the test cassette from the upstream machine, transfers it in a special form and inserts it into the pouch. Finally, the bag is closed by thermal sealing and transferred to the delivery belt.
Christoph Waldenmeier, Sales Project Consultant at OMRON Industrial Automation Europe, comments: “During the past six months of the coronavirus crisis, the co-operation with Senova and Kraus has continued to develop. The latest generation of COVID-19 tests are now produced in a new production hall. The production lines are fully equipped with OMRON technology.“
He adds: “We are pleased that we can use our technology to support the global efforts in the fight against the coronavirus to a small extent. In times like these and in a flexible production of the future, co-operation is the be-all and end-all.“ Joachim Kraus adds: “The fast and uncomplicated implementation of this challenging project was only possible thanks to the perfect interaction and good chemistry between the customer, machine builder and system and control supplier.“

Recently, the demands on the production capacities at Sun Chemical in Frankfurt am Main increased considerably, so that the need for appropriate automation quickly became clear and was also confirmed by the US group management. The goal of the new solution: to achieve a sustainable improvement in the efficiency and productivity of existing processes.
The premises in an industrial area in the eastern part of Frankfurt posed several challenges for the planning: The limited space in the older building had already been used to a considerable extent, the floor was partly uneven, the ceiling was low and there was a wide window front directly behind the future robot cell. Nevertheless, the new robot system had to be integrated into the existing production and a smooth pallet transfer had to be possible.
Initial contact with the system house and robot manufacturer was established at Fachpack 2018 in Nuremberg. While offers were also obtained from Denmark, Spain and Italy, the choice quickly fell on Becker Sonder- Sun Chemical in Frankfurt am Main Maschinenbau and Kawasaki Robotics after the initial meeting at the trade fair.
The presence in Germany was definitely a decisive factor: high quality and flexibility, reliability as well as the local proximity of the Becker Group were important.
In particular, maintenance and fast support are enormously important for smooth operation of the plant and long-term investment security. Becker Sonder-Maschinenbau has been working with Kawasaki Robotics products for a long time, and the customer was also quickly convinced of the quality and reliability of the robots.
Shortly after the FachPack, Sebastian de Man, Division Manager Robotics of Becker Sonder-Maschinenbau, visited Sun Chemical for the first time and got an idea of the requirements, production and infrastructure on site. After examining several options, the order was placed in April 2019 and the new system was already commissioned in October of the same year.
It has not been the first experience with robots for Sun Chemical in Frankfurt: For several years now, a cartesian robot with three linear axes from a Danish manufacturer has been used elsewhere in the production facility. However, the 5-axis jointed-arm palletizing robot from Kawasaki Robotics clearly surpasses it in terms of precision, flexibility and working range.
Production at Sun Chemical Frankfurt is usually run in two shifts and can be run through the new robot cell without interruption. However, three shifts are also possible at any time if required and are used regularly depending on the required production volume. The robot-supported system allows maximum throughput without breaks.
Manuel Krause, Engineering & Maintenance Manager Germany at Sun Chemical, explains: "With two shifts, automation by robots definitely pays off. For three shifts it is absolutely essential".
The finished ink is filled into 3 kilogram buckets, sealed and automatically labelled.
A Kawasaki RD080N robot is equipped with a specially designed vacuum gripper and transports the closed, labelled buckets to a waiting pallet. With a maximum payload of 80 kg and a reach of 2,100 mm, the RD080N is designed specifically for palletizing applications. With industry leading work range and reliability, the high-speed palletizing robot helps companies improve production line efficiency.
As soon as the pallet is completely loaded, it is removed by an employee via a roller conveyor for film wrapping as well as further loading and replaced by an empty pallet. The robot can resume operation immediately after the change.
Particularly good for long-term planning: the system and the robot are currently running at only 50 to 80 percent of the available maximum capacity - there is still plenty of room to adapt to increasing requirements.
The system forms the end of the production process and can quickly become the bottleneck of production. But since it has been commissioned, the production capacity has been consistently higher.
In addition to increasing production capacity and long-term cost savings, the focus was also on relieving the ergonomic strain on employees. The handling of the paint buckets, the pallets as well as the regular readjustment were challenging for the employees in the long run - especially for older colleagues or those with physical complaints.
Despite initial scepticism, the system and the robot were quickly accepted and appreciated by all employees, reports Manuel Krause: "The solution must be robust and reliable - then it will be accepted. And if it is not too complex and makes the daily work of our colleagues easier, even more so".
The next step in the automation of Sun Chemical's Frankfurt production is already planned: A similarly designed robotic cell for palletizing the paint buckets - but with two parallel feeders. At present, a manual feeder is used at the point of production, but this will be automated together with a second one in the future.
The new double-deck palletizer - an innovation at Sun Chemical - will reduce downtime to a minimum. If the employee removing the finished pallet is on a break or otherwise not present, the system will stop until the pallet is removed. "This can take up to 30-40 minutes in individual cases - valuable time in production and filling. With the new system, the robot can continue packing even when the pallet is full and the system can continue to run around the clock," says Krause.
A centrally positioned Kawasaki robot takes over the palletising. The new system will also have directly integrated labelling and will also handle larger containers and other coloured products. This would also significantly reduce the workload of employees. Becker Sonder-Maschinenbau is currently implementing the design and first tests - the commissioning of the new system is planned for late 2020.
OMRON’s LD mobile robot fleet navigating autonomously through the production facility © OMRON
With over 50 years of experience, VOLA is one of Denmark’s leading manufacturers of high-quality sanitary fittings, with product lines such as bathroom mixers and kitchen taps. Due to increasing market demand for a wide range of product variants, VOLA decided to expand its plant by 5,500 square meters. This area includes a new high-bay warehouse, an assembly hall and facilities for the delivery of goods.
In one of the most ambitious projects involving industrial mobile robots in Northern Europe, VOLA commissioned a fleet of nine OMRON LD robots. These have replaced roller conveyors, leading to a more flexible production and logistics set-up that matches the company’s single-piece production process, in which everything is produced to order.
Peder Nygaard, factory director at VOLA, explains: “Roller conveyors are really efficient, but I don't know what our production set-up will look like in ten years. If we installed more conveyors in the production line, we could quickly compromise the flexibility on which we pride ourselves. That’s why we’ve chosen the autonomous robots from OMRON, as these are much more flexible.”
The robots have been tasked with transporting components and finished items back and forth between the high-bay warehouse and assembly hall. The robots are controlled by the OMRON Enterprise Manager - a unique fleet management system which, like a control tower at an airport, ensures a smooth flow of traffic. The system tells each individual robot where and when to move, including when it’s time to take a break to charge its batteries.
“There are only a few robot manufacturers that are able to handle the advanced fleet management of so many robots. The solution by OMRON is by far the best that we’ve seen in the market, and this is why we opted for the LD mobile robots,” says Peder Nygaard.
To take full advantage of its investment, VOLA designed the new factory so that it is ideal for collaboration between people and robots. For example, the locations of the mounting tables and walkways are designed for safety, convenience and the free movement of both people and robots.
The workflow has also been designed to ensure the perfect alignment of the tasks of the workers and the robots. Previously, the assembly staff would call up a job list on their screen but this is now managed by the central team. The job list will appear on the employee's screen onc they have scanned the item that the robot is transporting.
“We are implementing something that hasn’t been seen before. That is why we also recognize that there will be an adjustment period when we have to ensure that our employees become used to collaborating with the robots,” says Peder Nygaard.
According to OMRON’s Area Sales Manager, Thomas Jansen, the project has taught him a lot. “Implementing mobile robots may be seen simply as a question of plug-and-play. However, we need to make sure that aspects such as the production layout, logistics and organization are taken into account in the planning phase."
The nine mobile robots at VOLA are scheduled to be supplemented by eight more robots in the next phase of the project.
Kawasaki Heavy Industries, together with Medicaroid Co., Ltd. and Sysmex Corporation, has been working since the early stages of the spread of COVID-19 to develop an automated PCR testing system using robots to protect healthcare workers from infection risks.
This system automates and automates processes that involve infection risks using robots to protect the safety of medical personnel and to implement the procedures from the acceptance of specimens to the notification of test results in a short time (within 80 minutes) in cooperation with hospitals.
The system also packages the inspection system into 40 foot containers (processing capacity per container: 2,000 samples/16 hours), making it easy to move to a place where many people gather, and by increasing or decreasing the number of units, it is possible to flexibly respond to the number of inspections required.
The use of general-purpose robots makes it easy to change the process, making it applicable to various infectious diseases such as influenza.
First, Kawasaki started introducing pre-flight inspections at international airports in order to recover demand in the airline industry, which has been greatly affected by the decrease in international traffic. On September 22, 2021, the PCR Test Service for International Departure Passengers started at the PCR Test Center opened in Kansai International Airport (KIX) with Kansai International Airport Clinic of Kinki University School of Medicine.
With this service, the inspection time at the airport can be significantly shortened, and a negative certificate can be issued in as little as three hours from the reception of the PCR test.
In addition, by installing them at stations and at venues for sports and large-scale events, Kawasaki will contribute to the recovery of people's traffic and the elimination of restrictions on activities, and to the resumption and restoration of economic activities.

This case promotes the intelligent development of the automotive industry, ensures a sustainable consumption and production mode, and promotes inclusive and sustainable industrial development by innovating manufacturing technology.
The body-in-white door/hood/lid production line is the production line with the most challenging automatic integration in the automotive field. This time, Risong Technology launched the leading automatic, intelligent and flexible door/hood/lid production line and took the lead in mass production. Adopting all-round high-tech automation schemes—"Intelligent Visual Guidance Technology", "Intelligent Tightening Technology" and "Intelligent Quality Control Technology", with many core technologies reaching the international advanced level, the assembly line belongs to the model line case of intelligent manufacturing industry.
The production line includes processes such as automatic grabbing from the EMS line in the air, automatic calibration, gap measurement, visual guidance, automatic tightening assembly, quality monitoring, and torque monitoring, and deeply integrates intelligent elements such as laser and binocular vision, automatic tightening system, information monitoring system, flexible NC, high-speed conveying, and intelligent IoT. The entire line is fully automated by NC fixtures, and the shuttle system is used for body conveying, thus realizing the automatic assembly for the four doors, engine hood, trunk lid, and rear bumper in the takt time of 54 second/unit, automatic tightening of 64 screws, 4-second station conveying, and mixed line production for 8 models, with an annual production capacity of 200,000 units. It is of innovative and advanced significance to have achieved a high automation rate, high production efficiency, high production quality and high flexibility of automatic assembly.
It is difficult for people to travel at high speed under extreme load, but robots can do so with the help of technology.
Risong Technology applied the self-developed ultra-high-speed conveying technology to the assembly and adjustment line of the door/hood lid of the vehicle body, and adopted the reciprocating circular conveying device; through the developed two forms of lifting in the middle of the body and lifting the doorsills on both sides, and through the auxiliary motion control unit cooperating with the multiservo drive system, the assembly and adjustment line has achieved high-speed and accurate conveying, and created a record of conveying among 18 work items of the body in white in 4 seconds! The assembly line not only ensures the stable conveying, but also has the advantages of adapting to multi-model production and occupying a small space, which greatly improves the production efficiency! The entire line is able to complete the intelligent assembly of the four doors, engine hood, and trunk lid for one unit of vehicle in 54 seconds.
In the era of high-speed operation and constant change, people's pursuit of vehicle models is also changing with each passing day, and the demand for high elasticity, flexibility and customization of automotive manufacturing becomes inevitable. The NC flexible positioning system developed by Risong Technology enables the assembly line to realize the collinear production of any vehicle model, random mixing and seamless switching in the production process. The assembly and adjustment line is provided with more than 230 sets of flexible NC positioning systems, which are capable of seamlessly positioning and grabbing the body chassis and door/hood/lid of each vehicle model, thus realizing fully automatic and random switching, satisfying the requirement of random mixed collinear production for 8 vehicles, and realizing the maximum production efficiency in the minimum space.
The flexible mixed production for 8 models is a big challenge for the assembly and adjustment line. The mass production in the door/hood/lid area needs to be matched with the mixed production in the assembly line exactly item by item. In the project, through nearly 100 logic programs in each location, with the help of vehicle type identification and vehicle type information conveyed by MES, each door is intelligently and automatically matched and then conveyed to the assembly line, thus realizing the intelligent system. The flexible technology can be controlled independently, so that automotive manufacturers can easily adjust the takt time, production models, etc., achieve high flexibility and high customization, and reduce production costs such as the costs in updating automotive manufacturing devices and upgrading personnel skills.
While human visual recognition is limited, machine vision can be accurate and precise. In unmanned intelligent manufacturing, machine vision plays a major part in ensuring that the production quality reaches the standard. The assembly and adjustment line consists of 4 sets of vision systems, and the 3D laser vision accuracy is as high as 0.1 mm. The vision guidance technology sends the deviation value to the robot controller after the accurate comparison of the measured images with calculation, automatically corrects and compensates the robot's motion trajectory, and guides the robot to the accurate actual working position, thus realizing the accurate grabbing and positioning of the mounting holes of the vehicle body, the door and the door hinge, and the accurate measurement and assembly of the door frame of the vehicle body. The machine vision intelligent assembly technology developed by Risong Technology has the characteristics of a large measuring range, good flexibility, and high precision; it can realize automatic assembly with a high automation rate, high production efficiency, high production quality, and high flexibility.
In terms of quality control, the "quality door system" introduced along with the assembly and adjustment line is a model of intelligent IoT. The system collects all quality information of the entire production line and sends it to the cloud platform to form a complete data feedback and monitoring database. By comparing and analyzing the fluctuation through big data, the assembly quality of each vehicle body can be traced at any time, and the information of each production cycle can be monitored, thus forming a complete closed-loop production line system from automatic production to quality monitoring and feedback. Furthermore, the defect removal and process optimization are completed, which ultimately improves the automotive manufacturing quality and increases the manufacturing efficiency, while effectively avoiding the possible loss due to device failure.
In this case, through innovative and advanced manufacturing technologies, it promotes the intelligent development of the automotive industry, ensures sustainable consumption and production patterns, and promotes inclusive and sustainable industrial development. It also further strengthens the implementation methods of sustainable development and activates the global partnership for sustainable development through technological innovation and global promotion and popularization of new production technologies. It complies with Articles 9, 12 and 17 of Sustainable Development Goals.

Intelligent Welding Cloud Platform © Risong Technology
The project case was developed by Guangzhou Risong Intelligent Technology Holding Co., Ltd., and was selected as the application direction of platform integration innovation for the 2020 Industrial Internet Pilot Demonstration Project of the Ministry of Industry and Information Technology. To promote the digitalization, networking and intelligent transformation of enterprises and accelerate the integration of manufacturing and Internet, Risong Technology has established a remote operation and maintenance platform for robotic and intelligent devices based on remote operation and maintenance of robots and aiming at process data management. The platform integrates technologies such as the device cloud platform and process expert database, and can provide customers with services such as device status monitoring, operation and maintenance order management, spare parts management, fault statistical analysis, spot check and tour inspection, remote operation and maintenance assistance, etc., thus enhancing customer service experience and increasing customer engagement, from selling devices alone to providing customers with digitalized factory overall solutions. Therefore, the corporate competitiveness and profitability are improved. The implementation of the industrial Internet platform project has helped us realize the transition from the traditional on-site service to the remote robotic operation and maintenance plus mobile app service, greatly reducing the number of business trips and reducing carbon emissions. The number of after-sales service personnel has been reduced by 30%, thus saving labor costs and enhancing the sustainable corporate competitiveness.
The project provides an efficient technology for remote cooperation and communication based on the industrial Internet platform, integrating the industrial Internet, cloud computation technology, mobile communication, etc., with the remote device operation and maintenance as the target application scenario, and has developed a remote device operation and maintenance system, providing reliable data bases for operation and maintenance service personnel through the cloud platform, and effectively solving some common difficulties and tricky points in the operation and maintenance processes of the industry.
In this project, artificial intelligence technology is applied to industrial application scenarios, and advanced AI technology is used to guide and assist actual production, thus reducing labor costs and improving production and management efficiency of enterprises. As the foundation of industrial artificial intelligence, huge amounts of high-quality operation, maintenance and process data is particularly important for intelligent manufacturing enterprises to become digitalized and smarter. According to its rich experience in the industry and advanced information technology, Risong Technology has developed a process management platform based on IT-based management methods, which can effectively manage all kinds of data generated in the production process, and with overall consideration of historical data, recommend the optimal parameters according to the target scenarios, effectively improving the accuracy of parameter selection, reducing the rejection rate and shortening the time for launching customers' new products, and fully activating and utilizing the company's invisible data assets.
1. Methods and measures
Firstly, by combining the experience of engineers with information management technology, the process management platform can help enterprises effectively manage the process data involved in various industries and processing methods, and fully solve the problem of lack of effective management methods due to the wide range of processes involved.
Secondly, besides process data, the process management platform also provides data sheets such as the device library, joint library, and knowledge base to help enterprises manage more process data. In addition, the process database utilizes the process data accumulation by Risong Technology for years and advanced artificial intelligence technology to further develop the automatic planning of path and process parameters on the traditional process management platform, and automatically complete the functions of process design, process flow optimization, and quality prediction, so that enterprises can obtain direct practical value from the data, and the accumulated data can guide the process links, reduce the production and management costs of enterprises, and promote the transformation of enterprises into digital and digital-driven enterprises.
The remote operation and maintenance module of Risong Technology Industrial Internet Platform integrates the knowledge base of Risong Technology robot corrective maintenance, which can effectively support Risong Technology's field engineers, partners and customers in detecting, checking and dealing with various problems in the operation of devices.
2. Main work
The process database expert system independently developed by Risong is based on artificial intelligence technology. It realizes automatic planning of path and process parameters through machine learning and deep learning, and automatically completes process design, process flow optimization and quality prediction. According to the process qualification data and production verification data, the database can carry out self-learning based on the Internet of Things, using controllers and sensors to acquire all kinds of parameters and quality data, constantly improving the database, and realizing self-adaptive and self-adjusting advanced process technology through artificial intelligence technology.
3. Issues to be solved
The service objects, service scenarios and issues of the project include but are not limited to: (1) For device manufacturers: improving after-sales efficiency and reduce after-sales costs, increasing after-sales revenue, improving sales of devices and accessories, and providing big data support for product improvement. (2) For device users and operators: improving production efficiency and reducing energy consumption, preventing device failure and reducing losses, improving operational efficiency and reducing maintenance costs, improve product quality and reducing production ramp-up time, and reducing production cost.
The platform can interact remotely to effectively reduce the contact frequency between people and the spread probability of the COVID-19 pandemic. Today, when the pandemic is still raging, it can play an important role in ensuring the normal operation of customers' site devices, showing strong resilience. Different from the traditional site-oriented face-to-face operation and maintenance assistance, the platform fundamentally eliminates the possible spread of the COVID-19, so it ensures the health of operation and maintenance personnel and service personnel, and at the same time effectively ensures the normal operation of customer site devices. In the face of the impact of the COVID-19 pandemic, thanks to innovative operation and maintenance methods, the platform is not affected by the pandemic at all, and it is full of resilience.
The platform can significantly improve the timeliness and economy of the platform's participation in corporate operation and maintenance businesses, reduce energy waste and effectively reduce carbon emissions. Traditional operation and maintenance methods require operation and maintenance service personnel to provide on-site services for customers. For both Party A and Party B, the timeliness and economy of operation and maintenance services are not high. For Party A, failure to locate and solve problems the first time when faults occur means device downtime, which means idling of other devices and letting personnel waiting. For Party B, whether arranging personnel for long-term on-site attendance or on-site service after problems occur, it means the additional transportation cost and the waste of effective working hours. For traditional service organizations or departments, the annual transportation cost is a high-expenditure item. All these can be effectively solved after the emergence of the remote operation and maintenance mode. In the remote operation and maintenance mode, after problems occur, the timeliness of operation and maintenance services is greatly improved, and Party B's transportation cost can be greatly reduced. The improvement in energy efficiency of Party A and Party B will eventually translate into the reduction of energy consumption, thus effectively reducing carbon emissions.
1. Characteristic achievements
Compared with the existing traditional process database, Risong Technology's process management platform covers a wider range of industries, involving more comprehensive processing methods and processes, and incorporates the expert system based on process big data into the database, which not only realizes efficient data management, but also realizes information extraction from data to guide the processes for improving production efficiency.
With a wider range of industry standards and data and full coverage of all kinds of process specification parameters, the real omni-directional, multi-angle, and high-efficiency data management is realized.
With "data-driven" as the core idea, the functions of self-learning, self-adaptation and self-adjustment are realized to a great extent using artificial intelligence technology and advanced process technology.
The establishment of the process management platform is, so to speak, able to meet the needs of enterprises for data management, and at the same time, it can generate direct guidance for the process through the expert system to help reduce production costs and improve efficiency. With its knowledge and experience in manufacturing technology, management technology and information technology application, the project is obviously advantageous in competitiveness.
With this project, Risong Technology can share and exchange on-site experience with its partners and customers, and form a knowledge system of device operation failure among them, so that the three can fully communicate in the system, and make use of the advantages of the Internet, so that more customers can experience more efficient and considerate on-site support services.
2. Experience that can be replicated and popularized
Based on the industrial Internet, the project can form solutions such as remote device operation and maintenance and process management, solve key problems such as process optimization and intelligent tour inspection, and form application cases in automotive equipment and construction machinery industries, and has the feasibility of being promoted to other industries.
This project can accelerate the transformation of the manufacturing production mode, management mode and business paradigm, and help improve the quality of manufacturing products and services. After the first demonstration of the project technology, its technology and application mode can be extended to many fields such as aviation, aerospace, shipbuilding, machinery, automotive, electronics and electricity. The project is of important theoretical significance and practical engineering value.
On the basis of comprehensive consideration of advancement, operability, economy, industrialization and other factors, the research scheme and technical route are formulated based on the relevant research results of the relatively mature and advanced technology and the existing corporate technical solutions. Through pilots and demonstration, new models and formats that can be replicated and promoted will be formed, promoting the innovative development of the industrial Internet and artificial intelligence.
The project establishes resilient infrastructure, promotes inclusive and sustainable industrial development, and ensures sustainable consumption and production patterns by accelerating innovation. In addition, it also further strengthens the implementation methods of sustainable development and activates the global partnership for sustainable development through technological innovation and global promotion and popularization of new production technologies. It complies with Articles 9, 12 and 17 of Sustainable Development Goals.
In addition to intelligent image processing, this technology project for logistics also uses a roll-on gripper specially developed for gripping containers © Robomotion
But what if, in times of increasingly personalized production, the variety of parts increases? Often, these efforts become uneconomical. The same applies to the use of robots in warehouses, logistics centers, or in the retail trade: The variety of articles is extremely high and teaching in each individual object that a robot should be able to grasp is too costly.
In this context, AI technologies can make robots more autonomous and more flexible and enable new applications. Automation solutions become economically feasible even under challenging conditions. Researchers from Fraunhofer IPA are showing what such an example might look like in the deep picking project. Among other things, they are working with the company »Premium Robotics« and develop AI-based image processing solutions that enable robots to recognize and grip unknown packaging units on pallets.
In the past, classical image processing approaches that require a high degree of domain and expert knowledge were used for the localization and gripping of objects by robots. However, these methods are often not sufficient for more demanding tasks, such as gripping closely stacked products that all have a very similar appearance. In addition, the time-consuming training of new products is another obstacle. An experimental setup developed by Fraunhofer IPA and Premium Robotics illustrates the use case and benefits offered by AI. The closely stacked objects on the load carrier cannot be gripped or approached arbitrarily without affecting other objects. The task was to investigate different approaches for object detection and to test their application in the field of goods picking by robots.
In addition, methods based on convolutional neural networks (CNN) for object recognition and pose estimation were investigated. Since training new products is correspondingly costly – training samples of image data have to be generated and manually annotated – the model training was performed in a simulation environment and the trained model was subsequently transferred to the real world. Successfully tested objects were all kinds of packages like open and closed boxes, trays with bottles, cans and cups, transparent objects, different types of packaging of any shape encountered in a warehouse and all of this under challenging illumination conditions and background reflections.

Over forty percent of European employees report having to work in tiring or painful positions more than one quarter of the time, with 32% being called to lift heavy loads according to Eurofound. In the U.S. MSDs cost approximately one trillion dollars in treatment and lost wages in 2014, accounting for 5.76% of GDP, exceeding defense spending for that year according to the United States Bone and Joint Initiative.
Robots carry out dull, repetitive and frequently unergonomic work, fetching and carrying loads and completing tasks that often cause muscle strain. For example, Svedplan uses a fleet of 30 robots to pack 2.6 million wardrobes per year into self-assembly packs for IKEA, doing the heavy lifting of placing the parts in the packages. Using robots has improved productivity at the plant by 45%, enabling Svedplan to remain competitive and avoid job losses.
Mobile robots fetch and carry materials in manufacturing, logistics,healthcare and retail, bringing parts to assembly lines, products to workers in e-commerce who are assembling orders, and linens and other items to nurses and nursing aids.
See the IFR paper ‘A Mobile Revolution - How Mobility is Reshaping Robotics’ for examples of how mobile robots are assisting workers
Robots support overall wellbeing by enabling workers – from production operators to nurses – to focus on more interesting and satisfying tasks. In manufacturing, for example, robots increasingly work directly alongside production operators as assistants. Many of these are ‘cobots’ – lightweight robots with specially rounded edges, able to slow or stop when a worker comes into their field of operation. They perform parts of the overall task that are the least ergonomic for the employee, while the employee completes the other tasks and ensures the process is carried out correctly. In this video, for example, the robot lifts and places heavy automotive transmission cases, and the production operator then completes assembly.
Exoskeletons – wearable robots – are increasingly adopted in manufacturing and logistics. They are used to provide support for lifting and for working in unergonomic positions, for example screwing parts overhead. They consist of a frame, made from hard or soft materials depending on the manufacturer, attached to the user’s body generally at the hip as well as the thighs and upper-arms. They can be mechanical, providing support once the wearer’s arm is in place, or motorized, providing extra force for lifting.
There are also wearable robotic stools which enable workers to sit when part of their work is carried out in a stationary position. These lightweight exoskeletons are attached to the feet and hips and adjusted to the wearer’s height and shoe size. They extend to allow walking and then compress into an ergonomic seating position when the wearer bends their knees.
At some point, nurses may wear exoskeletons for support in moving patients - however healthcare organizations typically have budget constraints which would require a lower price-point than is currently the case. However, other robotic support for lifting patients in hospital is being trialled. For example, the Patient Transfer Assist from Toyota Motor Corporation combines weight-supporting arms with a mobile platform to help caregivers transfer patients from beds to chairs or toilets and back.

An 800-bed hospital may handle up to 27 tons of materials every day, covering a distance of about 800 km. Nurses spend a significant amount of time fetching and carrying medications, linen and waste, walking at least 4 miles per day according to one study. Robots can significantly reduce this, giving nurses more time to focus on patient care. Mobile robots loaded with linens and medication can find their own way around hospitals, some operating lifts and opening doors.
For example, in a hospital in Garbagnate Milanese, Italy, shown in the YouTube video, mobile robots are used to transport material – including meals and medication, personal protective equipment, and waste material – to 147 reception stations throughout the 500-bed hospital. The robots navigate autonomously using an internal map and sensors to locate their position and avoid obstacles. They also navigate to charging stations when required. More information here.
Robots are increasingly interacting directly with patients and residents in care homes, with a number of assistance robots in trials.
For example, the Lio mobile personal robot from F&P Robotics is aimed at supporting healthcare professionals in nursing, geriatric institutions and rehabilitation centres by carrying out tasks such as greeting patients, grasping and carrying objects, offering and serving drinks, clearing dishes after meal, reminding patients of, and accompanying them to, upcoming appointments and providing entertainment. The robot navigates and re-charges autonomously, has a multifunctional arm and communicates by voice as well as through a touchscreen. (see video on YouTube)
Self-service robots that allow patients or care-home residents to selects drinks or snacks from a mobile vending machine are also being trialled. For example, the SeRoDi Service Assistant, developed by Fraunhofer IPA, allows care home residents to select from a choice of 28 drinks on the robot’s touch screen. The chosen drink is then served to them by the robot. The service assistant returns to the kitchen when empty, to be restocked by the staff before being directed back to the day room via smartphone. In addition to reducing workload for staff, the robot also improves residents’ hydration through regular verbal reminders to drink.

There are different modes of operation. In some cases, such as Jaco from Kinova, the robot arm is operated through the joy-stick or other device used to operate the wheelchair itself.
In other cases - like the Dowing from Focal Meditech shown in this YouTube video – the robot arm is a splint into which the user lays their own arm. The robot arm senses the motion intended by the wearer and calculates the support needed.
There are a number of other robotic aids for people with restricted motion in hands and arms, for example robotic feeding devices such as the Obi and the Bestic that are remotely controlled by the user from another part of the body (foot or chin for example).
Most electric wheelchairs use joysticks or other manually-operated input devices, which makes them unusable for people unable to move their hands and arms. Autonomous wheelchairs that respond to eye movement and can map their environment to navigate autonomously and go up and down stairs are being developed. For example, researchers at MIT in the US are working on a voice-controlled autonomous wheelchair for people who have lost mobility due to brain injury or the loss of limbs, but who retain speech.

Every year, more than 200,000 new robots are installed worldwide for handling. Of these, only a fraction in the per mille range performs bin-picking despite the task’s high potential. One reason for the little spread: Bin-picking cells are the first station of an interlinked production or assembly line. The balancing of such a line is based on the fact that each station provides a guaranteed output. Bin-picking brings along two uncertainties: It is often not guaranteed that the box can be emptied. Furthermore, the cycle time also increases significantly with increasing crate emptying. These uncertainties are often the result of suboptimal parameters which are difficult to set for non-experts.
For this reason, Fraunhofer IPA and Liebherr-Verzahntechnik GmbH, who have been working together on reliable, high-performance bin-picking solutions since 2012, are using artificial intelligence to automate the parametrization of new parts. AI based optimization methods are used to determine the best parameters for the localization of a given part. The parameters are rated based on several factors like the number of correctly detected parts or the accuracy. This automatic approach reduces the time needed for a manual setup by the operator and leads to a reliable detection of parts and therefore to a robust bin-picking process.
The robot detects the ordered items on the conveyer © Wipro
Wipro devised a smart packing solution with the features such as End-to-end orchestration by software, UI based order creation and tracking, Integration of robot, conveyor and computer vision, AI based volume estimation and stacking pattern generation in real time and Zero robot teaching.
The order is placed through the order fulfilment system. Once the order is triggered, the robot erects a carton from the stacked cartons. The robot system determines the volume of the empty carton that has been erected using computer vision. Then, formulates the optimum stacking pattern in the carton based on the order using Artificial Intelligence.
Interfaced with Wipro’s robotics software platform, the robot detects the ordered items on the conveyer, picks them on the go and places them as per the AI generated stacking pattern in the carton. Any outliers such as damaged or unordered items are segregated into a separate area. In case the items that are to be packed last arrive early on the conveyor, the robot moves them to a temporary storage and continues packing in the AI generated pattern.
Once the carton is packed with the ordered items, the robot closes the flaps and seals the cartons. The packed cartons are then palletized.
The shoe sole arrives at the robot for glue application on conveyer © WIPRO
Manual application of glue on shoe sole results in excess fills, under fills, glue being sprayed outside the sole. These result in glue wastage and inconsistent output. Automation with an industrial robot involves manual robot teaching for every variant so that the shoe sole can be precisely located. This is highly time consuming and requires skilled robot programmer to be available on floor.
Wipro developed a dynamic vision based solution that can detect any sole variant, generate the glue application trajectory and pass on the coordinates to the robot to apply the glue.
The shoe sole arrives at the robot for glue application on a conveyer. The sole is scanned on the move by a Photoneo vision camera. Wipro’s vision algorithm collects the point cloud data and generates the glue application trajectory.
Wipro’s robot camera interface software converts this trajectory into robot coordinates and communicates the same to the robot controller.
Once the coordinates are received, the robot moves along the trajectory and the Nordson glue dispensing system sprays the glue on the sole. This solution is agnostic of robot, camera, PLC and dispenser make and model. Any model can be integrated into the platform.

Challenged with the sudden rise in demand, Designed Mouldings implemented a collaborative automation solution in its product assembly application, increasing productivity and decreasing cycle time significantly.
Designed Mouldings witnessed a spike in orders during Covid-19, as border closures meant more companies were sourcing their products locally. “From a production volume of 10,000 to 20,000 products a month, we were facing orders of 50,000 to 100,000 caps a month. Manual assembly was no longer a viable option for us,” said Paul Neumeyer, Managing Director of Designed Mouldings.
Australis Engineers guided the installation © OnRobot
The company looked for an effective solution to automate their processes and increase their productivity. They reached out to systems integrator Australis Engineering – one of OnRobot’s distributor partners – who suggested a collaborative application and recommended that they start by selecting the end-effector; an integral part of the automation solution.
The OnRobot VGC10 electric vacuum gripper was an obvious choice for Designed Mouldings. With unlimited customisation to fit various needs, the small, lightweight gripper is perfect for tight spaces. The gripper also does not require external air supply, speeding up deployment while reducing maintenance costs.
The VGC10 gripper – integrated with a Techman Robot cobot – works as a stand-alone system and does not require extra cabling, piping or air, resulting in a collaborative application with a small footprint. This allows it to be easily moved and plugged in anywhere. Importantly, the collaborative application is able to work safely alongside employees; no safety fence is needed.
Simple and easy to use © OnRobot
Additionally, the VGC10 provides simplicity and ease of use. “Setting up the VGC10 gripper was fairly quick. While Australis Engineering provided us with some guidance, we were able to do the complete installation and programming ourselves within just three to four days,” said Daniel Neumeyer, Plant Supervisor of Designed Mouldings. “The simplicity saves us a lot of expensive engineering hours that is usually required with typical automation projects.”
The OnRobot VGC10 gripper is used to automate the sealing of wads on plastic caps. Wads are used to seal containers and protect their contents from deterioration or contamination through exposure to air, moisture or other impurities.
First, the cobot’s vision system detects the wad on the table. The image is stored in the cobot’s database and programmed to trigger the machine to move and send instructions to the VGC10 gripper to pick the wad up. The gripper then inserts the wad into the bottom of each plastic cap. Once the wad has been fitted, the gripper drops the assembled cap into a hole in the centre of the table, where finished goods are stored before being packed and shipped.
The shift from manual hand assembly to collaborative automation has helped Designed Mouldings shorten the production cycle time, increase productivity and maintain consistent output quality. Designed Mouldings has also seen a reduction in material waste by one to two percent, and employees are now relieved from a tedious task – allowing them to focus on higher value jobs.
The company is now able to cope with the increase in orders without putting pressure on their current workforce or having to hire any contract staff, saving costs.
“The OnRobot VGC10 gripper can easily complete a 20,000 product run in 24 hours – three times faster than if it were done manually. With a constant stream of jobs, we are expected to achieve ROI in six months,” said Paul.
With the successful implementation of the collaborative application with the VGC10, Paul and his son Daniel are looking at other collaborative automation opportunities. Specifically, Designed Mouldings is looking to use the OnRobot RG2 gripper to assemble filters for hospitals.
“As one of the leading injection moulding companies in the industry, ensuring we stay competitive is crucial. Collaborative applications through OnRobot is an important step towards securing our future and enhancing our competitive edge,” added Paul.
The VGC10 electrical compact vacuum gripper has unlimited customization possibilities. It has changeable suction cup options for nearly any application need. The VGC10 can fit into tight environments to extend your automation possibilities. It can lift small, odd-shaped, and heavy objects with a smaller robot arm. The VGC10 features two independently controlled air channels that allow it to act as a dual gripper with pick-up and release in the same action, further increasing efficiency and reducing cycle time. With no compressor or air supply needed, this compact electrical gripper is easy to move, and simple programming makes it quick and easy to redeploy for greater production flexibility. Seamless integration with the robot of your choice.
The Kawasaki RS005L is the centerpiece of the fully automated cell © Kawasaki
Order your morning latte macchiato conveniently via app from the bus, quickly scan the QR code and let the robot barista serve it fresh - MyAppCafé makes it possible.The 160 variants of coffee specialties - including espresso doppio, cappuccino, chocciato or latte - can of course also be ordered directly on the touchscreen.
The idea came to Karlsruhe-based MyAppCafé founder Michael Stille during a “Tatort” episode in which a catering robot played a central role. First conversations quickly began. A similar solution was already on the market in the USA - but without interest for the European market. Together with two other Karlsruhe companies, IBS and Rothweiler Feinwerkmechanik, Stille developed its own solution.
MyAppCafé delivers the whole concept - turnkey and automatically. The decisive goal during development was cost effectiveness: Each franchisee only needs to spend a maximum of one hour a day refilling and waiting, the rest is fully automated. MyAppCafé only needs to be refilled after around 650 issues - of course the system informs the operators in good time. An important argument for the fully automated gastronomy solution, says Michael Stille: “Almost no personnel is required, a maximum of one hour of working time for refilling and cleaning must be scheduled after 650 issues. By comparison, four employees would be needed to provide the same service. With our robot Barista, you are in the profit zone much faster”. The integrated fully automatic cleaning systems combine the highest hygiene standards with minimum effort.
A robot is the heart of the cell: The engineering office IBS has been a close partner of the international robot manufacturer Kawasaki Robotics for years. After reviewing and comparing several options, the choice for the robot quickly fell on Kawasaki - also by recommendation of IBS. The prototype as well as all further cells were built based on the Kawasaki Robotics RS005L.
With a maximum payload of 5 kg and a maximum reach of 903 mm, the RS005L is part of the universal R series for small to medium payloads, suitable for assembly, material handling, machine tending and many other applications. Its special design enables the high-speed robot to have a longer reach and an extended working range.
In addition to the technical aspects, the RS005L convinced Michael Stille with its appearance, which fitted well into the design of the cell: “We wanted to have a real industrial robot inside, not a ‘toy’. And Kawasaki was very accommodating to us as a partner and through the quality of the robots.”
IBS finally developed the approximately 7 square meter large cell according to the detailed ideas of Silence. The implementation was demanding, among other things for a smooth communication between Kawasaki robot, WMF coffee machines, the output and the app. Via business and technology networks in Karlsruhe, the experts were called in for all components and aspects. Thus the startup ROCK5 from Karlsruhe developed the intuitive App. Within a few months, the development led to the successful prototype, which completely met the high demands - full automation, intuitive operation and reliability.
Just in time for the Franchise Expo in Frankfurt am Main in November 2019 the MyAppCafé cell was ready for the market and was presented to the public for the first time - with great success and numerous inquiries. Home game in Karlsruhe: For the first MyAppCafé cell, the Postgalerie shopping center was quickly found as an optimal location - also easily accessible for tests and presentations. Besides Karlsruhe, there are already locations in Böblingen and the Stadtgalerie Heilbronn aktuell, Saarbrücken will follow soon.
After ordering the desired coffee specialty via app or touch screen, the Kawasaki robot takes a cup and transports it to one of the two high-end coffee machines of WMF type 9000 S+ as well as to two syrup stations and a specially developed milk system, if required. It then moves the finished coffee to one of the dispensing stations where it can be removed for immediate enjoyment. The robot can prepare and serve up to 120 coffee per hour.
A cool highlight: the hot drinks can be decorated with an individual text or picture on the milk foam using a food printer, at no extra cost. Even your own photos can be uploaded via app and displayed on a fresh cappuccino. “Our customers can be as creative as they like: They can upload a vacation selfie directly from Milan and order the printed coffee in Karlsruhe for their return,” says Michael Stille.
Sustainability and fair trade have been important components of MyAppCafé right from the start: the cup and lid are made of environmentally friendly and compostable corn starch and all ingredients have organic and fair trade seals - from coffee to optionally available soy milk.
The robot barista never gets tired: MyAppCafé is active 24 hours a day, seven days a week - without waiting or queuing. Practical in times of Corona: Payment is made with all common contactless methods, including EC and credit cards, PayPal, ApplePay and GooglePay.
The Corona pandemic has naturally slowed down the momentum, as in all industries, but new inquiries are still coming in every day worldwide. Among other things, talks are currently underway with several listed companies in Germany who plan to integrate MyAppCafè. On average, it takes two months from ordering a MyAppCafé cell to the start of operations at the desired location.
Even though Corona has slowed down the search for a location, the prospects are very positive: By 2021 at least 50 boxes should be in place in Germany. Demand is also strong internationally - the first cells in action as well as appearances at franchise fairs have generated interest from Dubai, the USA, Poland, Sweden, France and Israel, among others. As locations are so far among other things shopping centers, universities, stations or airports in the focus, but the possibilities for the integration of the robot-supported MyAppCafé cell are versatile.

“What integrator are you using?” A question Tim Mead, operations manager with Zippertubing in Arizona kept hearing as he visited robot manufacturers at trade shows. “But we wanted something that we could integrate ourselves. Something that would save us a lot of money and bring the installation down to a price point that made sense for us,” says Tim Mead. His company was facing a very large increase in demand for its thermal wraps used by automotive and aerospace industries to protect hoses, pipes and cables. On Zippertubing’s production line, workers had a hard time keeping up with the fast-paced, highly-precise, highly-repetitive task of correctly inserting the cable jacketing into snap machines. That’s when the company started to look into more user-friendly collaborative robots, or “cobots.”
“We chose Universal Robots’ UR5 for a few reasons. After a quick demo we realized this was a collaborative robot we could integrate on our own. We were also looking at the versatility,” says engineering manager at Zippertubing, Matt Hesselbacher, explaining how Zippertubing’s products can change from month to month. Safety was another concern as operators would be working around the robot, feeding it raw parts and take away the finished pieces.
“The biggest benefit we’ve found with the UR5 is that our product quality really has improved; the robot has been running for eight months now and we have gone from having some product returns to now zero defects on parts produced,” says Mead. “With the robot itself, we can specify 300 percent more tolerance on our parts than with manual operation,” he says, adding that Zippertubing’s customers are noticing this improvement as well.
Tim Mead’s background is in chemical engineering, not robotics programming, so he was initially hesitant to build a robotics cell from scratch. “The demo convincing us was done by Universal Robots’ distributor In-Position Technologies and it looked very straightforward, there’s also a lot of cool training stuff on the UR website” says the operations manager who used the free Universal Robots Academy to get up to speed after purchasing the robot.
The Arizona company programmed their first UR5 to pick up pre-cut fabric material that the cobot moves through a snap-set machine where five male snaps are inserted, then it moves over to a second machine where five female snaps are added. The 25 second cycle concludes as the UR5 presents the piece to a vision camera that inspects whether the snaps are added correctly. Depending on outcome, the UR5 is directed to place the finished piece in either the “good” or the “scrap” pile.
Zippertubing is now working on a more compact, second UR5 installation that reduces cycle time while increasing the quantity of parts to run after-hours by integrating a turntable for delivery of the fabric. “We can have the robot run all night and double our production output. We can also have it handle two or three additional parts and cover even more of our production,” explains Mead, detailing how the collaborative robots enabled the company to reduce its labor force by 32% in those applications. “We can now take that freed up labor and move them to other more customized high-skilled, high-demand sections of our production line, where our operators can use their skills in a more beneficial way.”
For change-overs requiring different tools, the company went to the UR+ Solution website, an online platform with certified plug & play products for UR cobots and found the Milibar tool changer. “The benefits of using this is quick changeability, adding a new tool to the end of the robot arm is not an issue now,” says Mead.
Zippertubing estimates about a two year ROI on their UR5 purchases. “The return on investment is not just a return on the money we spent on the robot and the system; it’s also a matter of quality for us and for our customers,” says Hesselbacher, who stresses that a continuous lights-out production will push the ROI much lower as well. The success of Zippertubing’s Arizona plant has resonated with its sister facility in China too. “Our Asia facility is totally manual at the moment, and they’ve reached out to us to see if we could build them some of these robotic cells,” says Mead, who will refine the next UR robot application and provide it to his Chinese colleagues. The Arizona company is now also looking at other tasks UR robots could automate. Sewing is one of them.
“It will be a unique challenge as we want the robot to do snaps and sewing with the same tool,” says Mead, who is optimistic that his team will get the sewing project figured out in the foreseeable future.

LQ Group is a giant trans-regional and comprehensive commercial group in FMCG industry, and it is one of the top 500 enterprises in China. LQ had traditionally used conventional human-operated warehouse system.
In order to boost efficiency and maintain its competitiveness in logistics distribution and retail supply chain within specific region, LQ invested high level of warehouse automation. At the near end of the system, four depalletizing cells with ABB IRB660 are designed to pick specific number of cartons according to the orders.
There is only one kind of cartons on each pallet; however, there are thousand kinds of cartons with various sizes, colors, patterns, shades, and etc. to be processed everyday which are not able to be handled by conventional robot solution. To solve these problems, Mech-Mind 3D vision system provided an alternative to ABB robot.
examples of cartons colors and cartons shape © Mech-Mind Robotics
Comprising with Mech-Mind industrial 3D camera, vision system (Mech-Vision), and code-free robot programming system (Mech-Viz), the automated solution aimed to reach 1000 cartons/hour for one robot station, the cycle time between each pick is 10s, which means the vision system should also support for picking three cartons at one time pick.
The Mech-Eye deep is mounted on a stand 1700mm above the top of cartons.
The max weight of one carton is 30 kg.
The FOV (field of view) is 1000*1200*1300 (length*width*height).
The recognize accuracy of vision system should be larger than 99.99%, the time consuming of the visions system should be within 2s and the locating accuracy is±3mm. The vision system is perfectly compatible with ABB robot and the communication protocol is TCP/IP.
The vision system should determine the coordinates and the pose of the cartons which should be picked; therefore the path planning and collision detection of the robot can be taken care of.
Multiple sizes and colors cartons for FMCG (length:600~300mm,width: 500~200mm,height: 500~200mm)

In order to reduce the downtime of waiting for new pallets, two cameras are installed on the left and right of the conveyor and guides the robot to execute the order alternatively. The pallets are conveyed to the left and right of the depalletizing station. Once the pallet arrives at a certain position, the host control system sends the signals of the cartons on the pallet including size, weight and quantities to the robot.
As soon as the robot receives the arrival signal from the host system, it triggers the camera to take a picture and sends the picture to Mech-Vision. The vision combines the coordinates and poses of cartons into grasping points and sends it to Mech-Viz.
The Mech-Viz receives the order information and grasping points, afterwards, it guides the EOAT on how many suction cups have to be activated in order to pick a specific number of cartons and which specific cartons have to be picked on the same layer; moreover, Mech-Viz should also inform the robot of the cartons direction when it is put on the conveyor.
Repeat the procedure.

The key element of LQ depalletizing solution are Mech-Mind industrial 3D camera, graphical machine vision software and intelligent code-free robot programming environment.
New and innovative automated systems are also helping companies minimize product handling to create more space on the production floor and meet social distancing requirements.
“We’re extremely proud of the work that our Authorized System Integrators and automation equipment suppliers have done throughout the pandemic,” said Mike Cicco, president and CEO, FANUC America. “We live in unprecedented times that require a rapid response to make protective and life-sustaining products, and minimize person to person contact, and I think everyone involved has answered the call.”
Robotic System to Line Track, Pick and Package COVID Test Swabs
As COVID testing escalates across the globe, a major producer of test kit swabs needed an automated solution to help meet the increasing demand. Interactive Design quickly engineered and designed a flexible system equipped with multiple machine vision guided FANUC SR-6iA SCARA robots to automatically orient, feed, and load swabs into horizontal form, fill, and seal packaging machines. FANUC iRVision allows the robots to locate the swabs as they are conveyed from the machines that produce them. Depending on the position of swabs on the moving conveyor, each robot accurately picks 75 to 90 swabs per minute.
“Interactive Design’s integration team responded at record speed,” said Nate Maholland, sales manager, Interactive Design. “These systems are going to start hitting the customer’s facility in less than half the time they would under normal conditions. We’re very proud to help at this critical time.”
Flexible Filler/Capper for Vials and Small Bottles
As cases of COVID-19 began to intensify across the U.S., a diagnostics manufacturer reached out to ESS Technologies to build two identical filling systems with automated cap torque for diagnostics vials to be used in manufacturing COVID-19 test kits. Speed and urgency drove the project, which required the system to fill up to 120 vials/min.
Though originally developed for vials used in COVID testing, the machines can be used for applications using vials or small bottles. Available in semi-automatic and fully automated configurations, ESS’ flexible filler/capper uses a circular puck conveyor system to transport vials or small bottles to the inline filling system. A timing screw drive positions six vials beneath the six-up diving nozzle assembly where a precise amount of diagnostic reagent is dispensed. The cap placement is automated using FANUC’s SR-6iA SCARA robots and a cap feeder. A three-up final torque station then applies the precise amount of torque to the caps. The machine uses Allen Bradley PLC controls and a 6 in. color touchscreen HMI for ease of operation. An optional 10 in. HMI is available. The system provides fast changeover - under 10 minutes.
In addition to filling and capping COVID test kits, a second diagnostics manufacturer has asked ESS to build several end-of-line packaging systems comprised of 13 robots for collation, cartoning and case packing sterile test kits. ESS has been able to offer fast delivery times for these systems, allowing the manufacturers to ramp up their important production capacity. According to Kevin Browne, president and founder of ESS Technologies, Inc. “Everyone at ESS immediately understood the urgency of building high speed, high performance packaging machinery to increase the manufacture of test kits and prepare for future vaccine packaging. As a critical manufacturer for the pharmaceutical and diagnostics industries, ESS worked with suppliers to keep the supply chain flowing, and we were able to deliver two complete systems in just a few weeks.”
Automated Assembly System for Respirators
A major manufacturer of personal production equipment (PPE) needed to quickly ramp up production of their respirators to aid in the fight against the COVID-19 pandemic.
PaR Systems was able to design and build four robotic dispensing systems in just five weeks. Each system includes a FANUC LR Mate 200iD robot for automated dispensing. Since implementing the system, parts are produced within 25 minutes, just a fraction of the time it took with the previous automation. Now, the customer is able to assemble nearly 20,000 respirators per week.
“I’ve never seen a faster or more seamless delivery. It was truly a collaborative effort between PaR, FANUC, our customers and suppliers - all united to help produce this important equipment towards a cause,” said Jon Sakry, SVP of Operations at PaR Systems. “Our team went from concept to install for the customer in just five weeks! We took advanced measures to ensure the health and safety of our employees and customer teams were not compromised, including working extended hours and weekends to meet deadlines, safely separating testing groups and maintaining safe social distancing measures throughout the entire production process.”
This example underscores PaR’s mission to help manufacturers solve production challenges with automated solutions to get critical supplies to those who need them.
“In my years at PaR, we’ve done some important work including protective equipment for our military personnel, and assisting with the clean-up at various nuclear reactor sites. I count this latest automated system to produce respirators that protect first responders as another very important project, and I’m proud we were able to deliver the system in an extremely quick timeframe,” said Dan Hagen, Business Segment Leader at PaR Systems.
Touchless Packaging System
Sealed Air, the originator of the BUBBLE WRAP® brand and CRYOVAC® food packaging technology as well as other sustainable packaging solutions has partnered with Soft Robotics to integrate their respective technology platforms to create an end-to-end packaging system. A key goal of this technology partnership was to minimize person to person contact typically found in order fulfillment applications. The new system uses Soft Robotics’ Superpick 3D piece picking solution that includes a FANUC LR Mate 200iD six-axis robot. The SuperPick system pairs Soft Robotics proprietary vision and software with the company’s patented soft gripper technology to accurately pick variable products from unstructured totes.
The new touchless systems will allow people to social distance, take them out of potentially dangerous areas, and enable them to manage the robotic system versus manually handling the products. It also gives companies dealing with a labor shortage the ability to meet their customers’ growing demands and reallocate their workforce to higher-level tasks.

“UVD Robot” by Blue Ocean Robotics drives autonomously and eliminates bacteria and other harmful microorganisms in hospitals © Blue Ocean Robotics
Infections caught during hospital stays account for around 37 000 deaths per year in Europe and almost 100,000 in the U.S. The cost of treating hospital infections runs to around €7 billion in Europe and US$6.5 billion in the U.S. Ultra-violet disinfection robots can destroy 99.9% of all microorganisms in a hospital room within 10 minutes. While the room must be empty during disinfection, there are no negative effects of the UV rays. These robots do not replace cleaning staff, who are still required to remove ‘hard’ stains such as blood and urine.
The coronavirus pandemic has rapidly accelerated the adoption of disinfection robots and expanded their use from hospitals to hotels and public spaces such as airports and public transport. However, the increase in infections resistant to antibiotics is also spurring a focus on the prevention of infection, particularly in hospitals. Drug-resistant diseases cause at least 700,000 deaths a year according to the World Health Organisation, which estimates this figure could increase to 10 million deaths globally per year by 2050.
Sales of professional cleaning robots increased by 20% to 55 million in 2019 over the previous year and the IFR expects this to be a booming market as a result of the COVID19 pandemic (IFR World Robotics 2020: Service Robots). Disinfection robots are provided by a wide range of suppliers and vary in design. Danish company Blue Ocean Robotics, won the 2019 IERA innovation award from IEEE and IFR and the Frost & Sullivan 2020 European Professional Service Robots Product Leadership award for its UVD disinfection robot, which moves autonomously around hospitals emitting UV-C light. The robot stops emitting if there is unexpected movement which would indicate a person entering the room. The robot uses LIDAR sensors to create a map of its environment which can then be marked up by an operator to show which rooms and other areas should or should not be disinfected. The robot then navigates autonomously around the hospital.
The TMiRob from Chinese company Taimi Robotics Technology provides three types of disinfection; UV, hydrogen peroxide and plasma air filtration which can be used separately or together depending on disinfection needs. UV-C, for example, cannot travel through objects and therefore cannot clean surfaces blocked from line-of-sight by other objects whereas hydrogen peroxide misting is very effective for full surface cover, but takes longer and requires more intensive preparation, such as removing absorbent material and sealing ventilation points.

While most disinfection robots move on small-wheeled bases, a number of companies such as Indian robot manufacturer Milagrow, and Siemens together with its Chinese partner Aucma, have developed disinfection robots that run on caterpillar tracks to expand the robot’s scope of operation to include steep slopes and uneven surfaces.
Robots are also being used to make hotels and public spaces safer for people during the COVID-19 pandemic. Not only are they used for cleaning, they are also being used to minimize human contact, for example providing room service deliveries in hotels.
Robot disinfecting the Hong Kong metro © MTR Corporation
A number of transportation companies are using cleaning robots. For example, Hong Kong transportation company MTR Corporation has deployed a Vapourised Hydrogen Peroxide Robot (VHP Robot) to clean train compartments and stations. The robot, developed by MTR and Avalon Biomedical sprays atomised hydrogen peroxide which penetrates small gaps that normal cleaning methods cannot reach. The robot can be operated remotely through a pre-programmed floor plan or it can be operated manually. East Japan Railway has used cleaning robots at major stations for some time. Pittsburgh (US), Hong Kong, Singapore, Heathrow (UK) and Narita International (Japan) are among the airports using cleaning robots. Pittsburgh airport has retro-fitted its existing floor-cleaning robots with UV fixtures, collaborating with Carnegie Robotics.
A number of hotel chains including Hilton, Intercontinental, Marriot and Waldorf Astoria are using robots for room cleaning and / or to make room service deliveries. Most hotels use robots to disinfect rooms using UV light following the regular clean by staff. Robot butlers feature a mobile robot base with a secure storage box. The ordered items are loaded into the storage box and the robot is then dispatched. These robots are able to navigate their way autonomously through the hotel – including using lifts - using an inbuilt map and real-time sensor data. Guests enter a PIN on the storage box to access their items. A number of hotels in Tokyo, Japan, used to house mildly ill coronavirus patients in an effort to unburden Tokyo hospitals, have used robots to greet guests and clean areas used by guests to pick up food and other necessities.

The company needed to quickly boost production of its protective respiratory face masks to meet a sudden rush of demand from Sweden and the rest of the world.
Tiki Safety installed an ABB IRB 2600 compact robot that places and picks masks in and out of a machine that molds a sealing rubber strip around the respirator. Automation with the highly reliable IRB 2600 robot has made production at Tiki Safety ten times faster, improved the quality of the life-saving masks and created a better environment for employees who are excited to work with the robot.
Pick and place masks between two sections of a production line.
There are busy days at Tiki Safety in Bro outside Stockholm. Demand for the company’s respiratory protection has grown exponentially both in Sweden and globally. In order to meet the high demand, production was streamlined, and the solution became an ABB robot.
“Thanks to the ABB-robot, we now have a cycle time that is ten times as fast. This enables us to meet our orders and help hospitals in Sweden and around the world to get products as quickly as possible, says Mikael Klockseth, CEO tiki safety.
Tiki is one of the most advanced and at the same time most easy to use respirators on the market, a unique overpressure mask with a small fan at the top. But even though the respirator is world class, the machinery of manufacturing did not keep as high a standard. In order to manage Tiki Safety to increase their production rate, 3Button Group together with ABB developed a tailor-made solution: a new production cell where an ABB robot, IRB 2600, picks masks in and out of a machine that mold the sealing rubber strip that is placed around the respirator.
“Thanks to cooperation with 3Button Group and ABB, we got a turnkey solution in record time. It works great. Already the day after commissioning, we were up and running and making masks at a rate quite different from the one we had in the past, says Mikael Klockseth.
The phase of production that had been modernised took six minutes earlier. Now it doesn’t take more than 40 seconds. And faster it will be. “In a week or so, we hope to be down to 20 seconds. It’s just amazing! In addition, no special competence is required to work with the new line, and less needlework than before provides better quality of the product, says Mikael Klockseth.
RobotStudio has been an important key to the fast and successful robot delivery. ABB:s programming- and robot simulation software can create, simulate and test a complete robot installation in a virtual 3D environment. When tool design and programming of Tiki Safety’s new robot cell was added to RobotStudio, everyone could quickly see new opportunities and make decisions.
“In RobotStudio we immediately saw that there was more time for the robot to do other things in the cell. Therefore, we will introduce our test station in the same cell, so that the robot tests the masks while it manufactures and molds the plastic parts. It saves us an enormous amount of time if we don’t have to test manually, says Mikael Klockseth.
Increased production capacity, higher quality and more parts in the same cell. The replacement of old messy machines with a modern robot brings many advantages. It has also been a boost for the working environment at Tiki Safety.
“The ABB robot has solved much of the machine trouble we had before. Thanks to the robot, production works without problems, and the staff is much better able to manufacture the product now. They think it’s fun to work with new, cool machines!
Tiki Safety is very pleased with the new ABB robot. Now the company is better equipped to meet the high demand for respiratory protection, and according to Mikael Klockseth, the next step is already being thought about.
“Since the technology has proven to work so well, we have talked about buying another ABB robot. Then we could double production.”
Robotic press tending reduced the scrap at HPM rate from 11 to 0.5 percent for an especially fragile part © Hitachi Powdered Metals factory
Back in 2005 Hitachi Powdered Metals faced two challenges at the same time. First a labor availability issue. It was very difficult to hire and retain skilled employees. And secondly, the customer demand to produce extremely small and fragile parts which were barely handable by hand.
The solution to solve both issues at the same time was robot automation. HPM started with a pre-used robot to get familiar with robots and gain experience. Fast forward to today, over 200 robots working at HPM’s Greensburg plant.
HPM started with a handling application to tend the fragile parts. With its electric magnetic gripper the robot was able to handle the parts more gentle than the most cautious employee, reducing the scrap rate of the new product from 11% to 0.5%.
Powdered Metallurgy (PM) or sintering is the process of compacting custom blends of elemental or alloy powders in prefabricated dies to efficiently make machine parts of varying complexity. Once compacted, the shapes are heated in a controlled atmosphere furnace to bond the particles and harden the parts.
Also known as green compacting, the process yields near-net components that typically use more than 97% of the initial raw material in the finished part. Custom powder alloy mixtures provide the ability to produce complex, even intricate parts that meet the strength and tolerance specifications required for highly demanding applications.
The Hitachi Powdered Metals (HPM) plant in Greensburg, Indiana is one of nine such Hitachi facilities worldwide. It specializes in producing valve train and transmission components for automotive tier suppliers in the United States, with a growing presence serving motorcycle and landscape equipment manufacturers.
HPM began a gradual investment in industrial robots in 2005, driven by the emergence of a tightening labor market and the opportunity to produce an extremely fragile product.
“We started with robots because we had a part to make for a customer that had small, very fragile teeth that couldn’t be handled manually, and at that point all of our compacting presses were tended by hand,” said Gregory Owens, president of the HPM Greensburg plant. “Reducing labor costs was also a factor, but shortly after the first installation a major automotive OEM opened a manufacturing facility in town, and our labor cost issue transitioned to a labor availability issue, as it became extremely difficult to hire and retain employees.”
In an effort to keep costs down and to minimize any exposure during the initial trial period, HPM purchased a used, vintage 1993, ABB S3 robot from CIM SYSYEMS INC. in nearby Noblesville, Indiana. James Adams, who had joined HPM several years earlier as a manufacturing development engineer, was familiar with CIM, the longest-tenured ABB Robotics Value Provider (i.e. system integrator) in the US, from his work with robots at his previous employer.
“CIM had a used robot that would allow us to ease our way into robotic automation, limiting our initial exposure just in case it didn’t perform as intended,” said Adams. “They also provided us some much-needed support with programming and integrating the system into the existing operation.”
When the powdered metal parts come out of the press, before they are hardened in the oven, they can easily crumble with even the lightest touch. With the newly installed robot, featuring an electric magnetic gripper to handle the part, the scrap rate of the new product went from 11% while manually tended to 0.5%.
“When the parts were manually being pulled out of the press there was considerable handling damage. The part could be imperceptibly deformed, but you wouldn’t know it until it came out of the oven five hours later. Properly programmed and outfitted, robots are much more gentile at handling the parts,” said Adams.
The new system allowed HPM to move several of the manual machine handlers to less mundane positions in the plant, reducing the stress of a repetitive task and reallocating the labor in a more efficient manner.
Over the next year HPM added five more used S3 robots, applying what they learned from the initial system to automate other compact presses. After 18 months HPM had saved enough on scrap and labor to invest in its first new robot.
Fast forward to 2019. Now with over 200 robots installed, the Greensburg facility has the same amount of employees as it did ten years ago, but produces four-times the volume, easily delivering more parts with less people than any of the global Hitachi PM plants.
“Once the first robot was installed for the fragile part, it became very obvious that we can really take advantage of further robot automaton,” said Owens. “Robots far exceeded our initial expectations, and with the labor shortages we continue to face, quite frankly I believe robots saved us from potentially not existing.”
With the success of the first robot, the pace of subsequent installations was steady. It took ten years to reach 100 installed robots, and then as business and the economy continued to improve, only four more years to reach the recently installed 200th robot.
When the opportunities arose, HPM continued to buy used ABB robots in good condition, though more and more new robots were added to the fleet. In fact, every robot added since #147 in 2015 has been new.
HPM’s installation base includes a range of ABB small- and mid-range 6-axis robots, one Delta robot and several recently added SCARA models. Together with 350 employees the automation investment is well utilized, running three shifts five to six days a week.
“Our corporate headquarters is in Japan,” said Adams. “Once they saw how the robots performed and the rapid return-on-investment, they were very supportive of our robotic agenda.”
Some of the robots, both new and used, are ABB Foundry Prime, IP67-rated models which have extremely well-sealed connections that protect the robots’ inner workings from the fine, sharp edged metal powders that float through the plant atmosphere. The many standard, IP65-rated robot models on HPM’s floor are very robust and have been able to withstand the dusty environment.
The proliferation of robots at HPM was supported by replicating existing applications and expanding automation to other functions in the facility.
After the installation of the first robot tending the compact press for the most fragile product, Adams and his team sequentially automated the removal of the compacts from other presses. Part of this process was to place each part on a scale to verify its integrity. Once verified, the part was placed on a conveyor leading to the furnace.
Additional labor efficiencies resulted, and with the deft touch of the robot, the scrap rate of the less fragile parts went from 7% to the same 0.5% of the initial part.
At the end of the conveyor the parts are put on sintering trays that, when filled, are placed in furnaces for the hardening process. This furnace-loading process became the second major function to be automated.
Continuing at a measured pace, robots were then installed to take the parts off the trays and place them on pallets, while also inserting dividers between each pallet layer.
“As we got more familiar with robots, we took what we learned and duplicated applications around the facility,” said Adams. “Programming became much easier, and on the last day of line installation we would tweak existing programs, copy and paste and we were up and running in a couple of hours.”
RobotStudio®, ABB’s offline simulation and programming software, became a valuable tool in expediting HPM’s increasing adoption of robotic technology. Built on the ABB VirtualController, an exact copy of the real software that runs robots in production, RobotStudio allows very realistic simulations to be performed, using real robot programs and configuration files identical to those used on the shop floor. With RobotStudio, Adams was able to design the optimal cell layout and verify its performance before integrating the robots in a particular operation.
“It is the best software ever developed,” said Adams. “It saves time and money both in creating systems for new applications and in replicating those we had already installed in other areas of the plant.”
The relative simplicity of replication exists only after a certain application has been installed and refined on the plant floor. New applications are often more challenging. After eighteen months and the successful integration of six press-tending robots, HPM had the confidence to engage vision-enabled technology, in its infancy at the time (2006), to robotically automate the complex “coining” or “repress” operation.
After parts come out of the furnace they can often warp, which requires them to be put in a press that coins them back to being straight or flat. Many parts have keyways or teeth that need to be placed in the mold with all aspects precisely lining up. Before the arrival of the robots, the parts being coined were handled by a hard automation system that, with many different product variations, required frequent, time-consuming changeovers. The changeovers were so long that backups of 250 product lots, each with approximately 100 parts were common.
With the vision-enabled robot there is no downtime. The robot is able to identify the part from group of many different parts, pick it up, radially orient it and accurately position it in the repress.
Because the vision system needed to interface with the latest robot technology, this was the first new ABB robot installed at the Greensburg facility. Soon after it was up and running, two more new robots were purchased for the same application.
“Prior to the installation of the coining station robot, the repress staff was working every day,” said Adams. “In six months after the first vision robot was installed there were no more backups and the staff had their weekends off!”
HPM used vision again down the road in the last of the major processes to be automated, the depalletizing of parts that had been sent out for specialized heat treatment. Though the parts are sent out neatly positioned on tiered layers on a pallet, they come back in relative disarray and are difficult to unstack. An ABB robot with integrated vision is able find the parts and grip them securely so they can be safely depalletized.
“That is one of the unique capabilities of ABB robots,” said Dave Fox, president of CIM SYSTEMS, who helped integrate the various vision systems. “The parts are really disoriented on the skids, not in uniform rows, with some being upside down. A typical 6-axis robot would have all sorts of singularity issues, getting into a position where it can no longer move. But the ABB robot using advanced singularity avoidance is able to find the parts, grab them and place them safely on a conveyor without missing a beat.”
Not surprisingly, a recent search for a more efficient system to inspect valve guides led back to robots, in this case a group of ABB SCARA (Selective Compliance Assembly Robot Arm) models, which are typically used for small part assembly and material handling.
HPM protocol calls for 100% inspection of all valve guides, which is quite an undertaking given the variety of parts that must be tested: 30 different size variations and 16 detect points for each part. With the prevailing hard automation testing system unable to sufficiently keep up with the volume, Adams began to search for a better system.
After looking at various options, all of which had too many moving parts and required complex engineering, Fox suggested designing a system around the SCARA robots, which ABB added to its portfolio in 2016. They were certainly fast enough, with great repeatability, and had a small footprint and an unhindered form of mounting that fit within a confined space.
A relatively simple system was designed with three SCARA robots picking individual valve guides from a hopper conveyor and presenting them to vision cameras and a stationary “comparator” at the various angles needed to access the 16 detect points. The parts that passed were placed on one conveyor and those that didn’t were placed in reject bins.
With the flexibility to dexterously handle each different part variation with similar ease, the system is able to inspect a part every two seconds, 30% faster than the previous method. Since the movements are confined to a short distance and the parts are very light, a six-axis robot would not work as effectively as the sleek, limited-reach SCARA.
“The SCARAs are a great addition to the ABB portfolio. If not for that solution Hitachi probably would have had to pursue another technology for part inspection,” said Fox. “It was nice to be able to find another application for robots, even though that wasn’t the first option that came to mind.”
One constant that has been on the scene, either in the foreground or the background, from the first robot installed at HPM to the present day is CIM SYSTEMS. Always available when needed, CIM has set-up HPM with new and used robots, helped program and troubleshoot, but perhaps most importantly, taught the HPM staff to do many things themselves.
When HPM integrated robots into a new application, with vision or otherwise, CIM did the set-up and programming, always mindful to share their expertise, including use of RobotStudio. During the occasional lull in HPM’s robot acquisition timeline, CIM was available to update programs, find elusive spare parts for older models or offer advice on working with robots across a range of vintages.
“As we hit each of the different processes we had CIM do the initial integration and programming. Once we began replicating processes across the plant we had learned enough to do a lot ourselves,” said Adams. “Because of his close relationship with ABB, Dave Fox always knows when new technology is coming down the pike and which robots would be optimal for our various applications. The support we got from CIM SYSTEMS and the service from ABB was an ideal combination.”
With such a long-standing relationship, it’s no surprise that when the first robot rolled off the line at ABB’s United States manufacturing facility in Auburn Hills, MI in 2017, it was commissioned by CIM at HPM. The one-of-a-kind IRB 2400 robot was custom-painted red, white and blue at the factory, and is positioned prominently at HPM’s facility, performing inspection and palletizing tasks.
“We are excited we were able to procure the first American-made robot for HPM,” stated Fox. “It is especially significant because the Indiana plant has the most flexible automaton of HPM’s many global facilities.”
HPM’s corporate management in Japan took notice of the major productivity improvements the Greensburg team achieved with robots, and in 2017 assigned Adams and Owens to lead a “Global Robotics” initiative to support the other Hitachi powdered metal plants around the world expand their use of robots.
The two-year program is past the midpoint and the affiliate companies are beginning to realize significant productivity improvements, even with the lower labor costs in the other countries.
Adams has set up ABB’s Remote Monitoring function at HPM so he or members of his team can see how robots are operating, and troubleshoot most issues from anywhere outside the factory on a laptop, tablet or smartphone. With the newer robots, HPM hopes to take advantage of ABB Ability Connected Services, ABB’s unified, cross-industry, digital offering, which provides real-time data about robot status and performance from any location.
HPM’s ongoing mission includes improving their operations with robotic automation.
“We expect to grow at 10% per year for the foreseeable future, and we must do whatever we can to remain competitive,” said Owens. “We are looking at what transmission parts we will be able to make for electric vehicles, and have set our sights on penetrating non-automotive segments like heavy equipment where powdered metal may be able to replace parts made of other materials at a lower cost.”
“I certainly anticipate the pace of robot installations to remain steady or even increase.”
