In an automated production process, an IBM 7535 robot locates a keyboard on a special XY table and then moves the table to accurately index the keyboard under a fixed inspection camera. A hollow drive sleeve attached to the robot arm locates over a drive shaft on the table to provide a coupling for X and Y movements. In a production process, there is a station illustrated by Fig. 1 plan and Fig. 2 side elevation. IBM 7535 robot 1 is mounted on base 2 together with XY table 3. Robot 1 has jointed arms 4,5. XY table 3 is moved by robot 1 via coupling 6, and is supported by linear bearings 7,8 on the X and Y axes, respectively. Figs. 3 and 4 show coupling 6 in detail. Drive sleeve 9 is mounted on robot 1 Z-shaft 10 and has an accurately machined bore 11.
