Mechanical fingers grasp like the real thing
F.Y. Wu and H.H. Asada
Robo-fingers could help humans get a grip. A new type of wearable robot pairs two tonglike digits with a wrist brace to give a person the dexterity of a seven-fingered hand.
After slipping on the contraption, users can palm a basketball, single-handedly twist off a bottle cap or hold a tablet computer and type on it using the same hand, MIT mechanical engineers Faye Wu and Harry Asada reported July 15 at the Robotics: Science and Systems conference in Berkeley, Calif.
Wu and Asada’s robotic digits, thick tubes that jut from the wrist, use a computer program to coordinate movements with the wearer’s hand motions.
