Interchangeable jaw holders are required to enable a robot to pick up either 8-inch or 14-inch diameter disks by their differing internal diameters. Shown and described is the hardware that the robot uses to pick up either size disk and to automatically change the hardware, as required. In Fig. 1, the robot arm 6 presents the robot hand 5 to which jaw holders are selectively attached. Each of the jaw holders 8 and 9 is retained by the robot hand, as shown in Fig. 2. The tapered projection 12 on jaw holder 9 is received in a similarly tapered but deeper recess 13 through which a vacuum is selectively applied through vacuum tube 15 to retain the jaw holder. As shown in Figs. 3A and 3B, the jaw holder sets for handling disks with differing internal diameters are retained, when not in use, in holding fixtures 17 and 18.
