ABSTRACT:
A robotic manipulator includes a main upright frame on which two extensible arms are journalled. One of the arms consists of a pair of laterally spaced lead screws connected together at their front and rear ends and the other consists of a lead screw or sprocket-engaged chain connected to the front connected ends of the two lead screws. The motors for extending and retracting the arms are mounted on the main frame. A tool at the forward connected ends of the arms are controlled by parallelogram linkages which are also powered by motors mounted on the main frame.
