A microcomputer controlled manipulator for tetraplegics has been programmed to allow a variety of methods of operation, including direct positioning and preprogrammed actions. The system has been driven from several input devices operated by the head and mouth. A television set is used as a visual display, enabling the controls to be relabelled as the user selects different modes of operation. The use of sensors in the hand permits certain functions, such as grasping, to be carried out automatically.
