General Motors and NASA are jointly developing a robotic glove that auto workers and astronauts can wear to help do their respective jobs better while potentially reducing the risk of repetitive stress injuries. I want one for typing please. Of course it needs a brain interface and needs to work much better than voice to text apps. Watch a video of the K-gloves below.
The Human Grasp Assist device, known internally in both organizations as the K-glove or Robo-Glove, resulted from GM and NASA’s Robonaut 2 (R2) project, which launched the first human-like robot into space in 2011. R2 is a permanent resident of the International Space Station.
When engineers, researchers and scientists from GM and NASA began collaborating on R2 in 2007, one of the design requirements was for the robot to operate tools designed for humans, alongside astronauts in outer space and factory workers on Earth. The team achieved an unprecedented level of hand dexterity on R2 by using leading-edge sensors, actuators and tendons comparable to the nerves, muscles and tendons in a human hand.
Research shows that continuously gripping a tool can cause fatigue in hand muscles within a few minutes. Initial testing of the Robo-Glove indicates the wearer can hold a grip longer and more comfortably.
“When fully developed, the Robo-Glove has the potential to reduce the amount of force that an auto worker would need to exert when operating a tool for an extended time or with repetitive motions,” said Dana Komin, GM’s manufacturing engineering director, Global Automation Strategy and Execution. “In so doing, it is expected to reduce the risk of repetitive stress injury.”
Inspired by the finger actuation system of R2, actuators are embedded into the upper portion of the glove to provide grasping support to human fingers. The pressure sensors, similar to the sensors that give R2 its sense of touch are incorporated into the fingertips of the glove to detect when the user is grasping a tool. When the user grasps the tool, the synthetic tendons automatically retract, pulling the fingers into a gripping position and holding them there until the sensor is released.
The current prototypes weigh about two pounds and include the control electronics, actuators and a small display for programming and diagnostics. An off-the-shelf lithium-ion power-tool battery with a belt-clip is used to power the system. A third-generation prototype that will use repackaged components to reduce the size and weight of the system is nearing completion.
“We are continuously looking for ways to improve safety and productivity on the shop floor,” Komin said. “Our goal is to bring this technology to the shop floor in the near future.”
NASA and GM have a long, rich history of partnering on key technologies, starting in the 1960s with the development of the navigation systems for the Apollo missions. GM also played a vital role in the development of the Lunar Rover Vehicle, the first vehicle used on the moon.
