A multipurpose tool which provides as many as three different attachment points for robotic fingers and maintains easy gripper exchange is described. As shown in Figs. 1-3, a basic, yet comprehensive End of Arm Tool (EOAT) gripper design is provided with the emphasis on flexibility, uniformity, ease of maintenance, and ease of EOAT exchange. Fig. 1 is a front view, Fig. 2 a right side view, and Fig. 3 a top view. The EOAT consists of the following components: body, left body 2, right body 3, two shafts (spring) 4, four bearings (ball bushings) 6, two gripper plates 5, four attachment screws 1, two springs 7, and finger-mounting surfaces A, B and C. The bodies 2 and 3 are machined from aluminum alloy stock. A robot-gripping surface (pocket) is machined to a standard set of dimensions.
