Abstract
A central base of a gripper is adapted to be attached to a robot wrist flange. Carriage rods and stabilizing bars extend outwardly, on both sides of the central base. Sliding carriages, which move along the carriage rods on linear bearings, each carry two flexible urethane grippers which are capable of expanding and gripping a part from the inside when the flexible grippers are pressurized. Each carriage when slid from a first position to a second position by an air cylinder, causes the second flexible gripper of a carriage to occupy the same position in space that the first flexible gripper of the same carriage, previously occupied.
