DETROIT: A few days ago, we mentioned on our Facebook page about BMW experimenting with a robotic backpack at its US plant in a move to improve worker safety. It acts as an exoskeleton that a factory worker wears on his back to help in the car assembly process, which can get tiring and monotonous if you are doing it day in and day out.

Here’s more news about such assistive technology seeping into the factory floor.

Robotic glove technology developed out of a partnership between General Motors and Nasa for use on the International Space Station is finding new life on Earth in health care, manufacturing and other industrial applications though a licensing agreement between GM and Bioservo Technologies AB, a Swedish medical technology company.



Working with GM, Bioservo will combine technology from its SEM GloveTM (Soft Extra Muscle) technology with the RoboGlove, a force-multiplying battery-powered wearable developed by GM and Nasa during a nine-year collaboration that included the launch of the humanoid robot called Robonaut 2 (R2) into space in 2011.

The RoboGlove uses leading-edge sensors, actuators and tendons that are comparable to the nerves, muscles and tendons in a human hand. One design requirement for R2 was to operate tools designed for humans, and developers achieved unprecedented hand dexterity. That technology was applied to the RoboGlove.

Bioservo will initially develop a new grasp assist device for industrial use that could increase human operator efficiency while reducing fatigue in hand muscles. Research shows fatigue can occur within a few minutes of continuously gripping a tool.

“Combining the best of three worlds – space technology from Nasa, engineering from GM and medtech from Bioservo – in a new industrial glove could lead to industrial scale use of the technology,” said Tomas Ward, CEO of Bioservo Technologies.

Ward described the technology combination as a major step toward introducing soft exoskeleton technology globally.

GM intends to be the first US manufacturing customer for the refined robotic glove and will test it in some of its plants. Bioservo will make and sell the new glove for a variety of uses including medical rehabilitation and any place additional gripping strength is needed.



“The successor to RoboGlove can reduce the amount of force that a worker needs to exert when operating a tool for an extended time or with repetitive motions,” said Kurt Wiese, vice president of GM Global Manufacturing Engineering.

GM briefly tested RoboGlove in a pre-production plant before looking for a partner to help refine it to fit different size hands and address other issues.
