NASA and GM have developed a new Robo Glove that is designed to make working with heavy tools and equipment a lot easier, the glove uses pressure sensors which are located in the fingertips to automatically tighten actuators that are located in the fingers to provide extra grip.
Without using the glove you may need to exert 15 to 20 pounds of force to grip a tool, but with the glove the force needed is reduced to between 5 and 10 pounds.
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.
