The future of collaborative robots

Third Quarter 2020 Editor's Choice Robotics & Mechatronics

Collaborative robots (cobots) that can work safely in the same environment as people have an important role in enabling flexible manufacturing and creating a competitive advantage for companies. A new generation of cobots is evolving from classical industrial robots in response to the needs of Industry 4.0. In applications where flexibility is key, as opposed to maximum production speed, collaborative robots are filling the gap in the robotics market with their extremely user-friendly software tools and integrated sensory functions. These now include machine vision systems, location capabilities and integration with warehouse systems.

Collaborative robots do heavy lifting

Cobots are gaining strength, although being lightweight. For example, the Omron Techman TM14M robot can lift goods up to 14 kg. While compliant with the ISO 10218 safety standard, which describes the interaction of robots and humans, industrial cobots are becoming actual team members in production and logistics environments, thanks to their lifting capabilities. This brings innovation to the factory floor through the harmonisation and collaboration of humans and machines.

Cobots can be deployed in a wide range of applications, such as production, testing, quality control, packaging and palletising, as well as intralogistics. For example, it is possible to support people in assembly processes at those stages where precision and repeatability are key. These robots can apply adhesives and seals with simultaneous quality control. Thanks to their repeatability, they are also perfectly suited for automating complex quality tests. Being able to do heavy lifting, with the proper safety equipment they can also be used as palletisers.

Collaborative robots are on the move

The new generation of cobots can be easily integrated with mobile robots. This cooperation is made more accessible thanks to the low weight of the latest robots, as well as the possibility of building mobile platforms on mobile robots, such as the Omron LD autonomous intelligent vehicle. Cobots can now be a natural part of a flexible, constantly evolving production environment in which the re-deployment of machines, line changeovers and conveyors are needed.

Cobots installed on mobile robots, for example, can become elements of innovative logistic solutions and provide complete sub-assemblies and semi-finished products for assembly stations, and finished products to be placed in stock or quality control stations. Cobots can effectively complement and augment people’s work in many discrete manufacturing processes.

Collaborative robots are becoming smart

Cobots are just beginning to contribute to innovation and competitiveness for manufacturers. The ability to carry out tasks performed so far only by standard robots, all easily configurable by local engineering staff, is an undisputed advantage. If we additionally consider the easier implementation resulting from the reduced need to provide typical robot security measures, and greater flexibility of operation, the return on investment can be very surprising.

If we add the capabilities of machine vision combined with artificial intelligence into the mix, the possibilities are limitless. A cobot can have a built-in intelligent vision system which provides totem pairing, object position, bar code identification, colour differentiation, and other vision functions. You can use gestures to guide the robot and the task by hand, as well as freely change the degree of freedom of the hand-guide function according to different conditions.

If you have seen Omron’s interactive table tennis robot, Forpheus, in action, you can imagine the possibilities for artificial intelligence combined with collaborative robots. Forpheus demonstrates human machine collaboration by combining vision with robotics and artificial intelligence at the machine level. It can play an interactive game and identify ping-pong balls in a 3D space in an identical way to the human visual system, as well as evaluate the players and judge their ability level, while a high-speed robotic arm moves in response to its AI controller, predicting smashes for example.

What does the future hold for Omron?

Omron and Techman Robot, the world’s leading company for collaborative arm robots that work together with people, recently signed an agreement to form a strategic alliance in the area of cobots.

Together they will provide cobots that can be used for a wide variety of applications such as electronics assembly, product testing and inspection. These robots will enable flexible manufacturing and increase the productivity and quality of production lines for customers in the automotive and electronics industries, as well as various materials handling operations in a broad range of manufacturing industries, to realise an innovative manufacturing environment where humans and machines work in harmony.
