ABSTRACT:
A robot arm preferably has at least shoulder, elbow and wrist joints with a lever arm extending between each of the joints. Individually powered modules are buit into each of the lever arms adjacent each joint to control the mutual attitude between the lever arm end and its associated joint. Thus, each of the lever arms between the shoulder and elbow and between the elbow and the wrist, respectively, has two of the modules. Each individual module is operated to adjust the attitude of the lever arm relative to the adjacent joint. Or stated another way, two of the module means are operated to adjust the attitude between two adjacent lever arms.
