Abstract
An actuator system provides force feedback to a master support. A first, second and third digit support are connectable by a finger mount to the thumb, index and middle, and ring digits, respectively. First, second, third and fourth actuators comprising pneumatic cylinders extend between the first, second, third and fourth digit supports and an "L" shaped palm support mountable on the palm of the glove. Sensors are mounted to the pneumatic cylinders to provide electrical signals on the positioning of the fingers. The signals are forwarded by a stand alone feature to a host computer. The host computer computes the positioning of the finger and provides feedback through interface to the first, second and third actuators. Azimuthal mounts connect the first, second, third and fourth actuators to the palm support for increased movement of the digits.
