Abstract: A robot drive assembly for moving a working tool in x, y, z and theta directions comprising three independent, coaxially nested tubes, each tube being driven around a common central axis by drive belts attached to separate drive motors located in a mounting flange associated with the outermost tube. The motors, and the tubes which they drive, provide horizontal rotary motion to a robot arm attached to the upper end of the outer tube and the wrist and elbow of that arm. A fourth motor controls vertical motion of the whole assembly. The robot system also includes motor position adjustment structure and belt tension structure designed for ease of use and to eliminate movement of tensioned components once locked in position.
