A wrist-mounted device has been developed by researchers at the Massachusetts Institute of Technology (MIT) that augments the abilities of the human hand through two robotic fingers.

The new device makes two-handed tasks like opening a letter or removing a bottle cap possible by using a grasping motion that mimics the movement of a hand.

"This is a completely intuitive and natural way to move your robotic fingers," said Harry Asada, a professor of engineering at MIT. "You do not need to command the robot, but simply move your fingers naturally, Then the robotic fingers react and assist your fingers."

Asada believes that the robotic fingers could be used to assist people with limited dexterity or disabilities, as well as for "other healthy people" who want to increase their own capabilities.
