General Motors has built a force-multiplying battery powered robotic glove. It will be used in factories and healthcare and other industries.
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.
Ward described the technology combination as a major step toward introducing soft exoskeleton technology globally.
GM intends to be the first U.S. 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 preproduction plant before looking for a partner to help refine it to fit different size hands and address other issues.
