Abstract
The movement of rotation of each element of the manipulator arm about the shoulder, elbow and wrist pins is controlled by a motor and a cable consisting of two oppositely-acting lengths by means of a pulley-block which carries at least two lengths, two pairs of pulley-blocks being located within a barrel unit. The length of cable which emerges from each pulley-block is passed over a return pulley carried by the shoulder pin and guided within a stationary manipulator body in a direction parallel to the axis of the barrel unit, each emergent length of cable being actuated by one of the motors mounted on the manipulator body.
