Abstract

A robot controls a multiposition Z-axis actuator through its digital in (DI) and digital out (DO) switches. A robot 1, such as an IBM 7535 or 7540 robot, for example, has a casting 2 attached thereto by screws 3. The casting 2 supports an electric motor 4 having its output shaft connected through a trans mission 5, which also is supported by the casting 2, to rotate a threaded shaft within a hollow tube 6. The threaded shaft within the hollow tube 6 has a thrust bearing movable vertically when the threaded shaft rotates and is connected to a shaft 7 so that rotation of the threaded shaft within the hollow tube 6 causes the shaft 7 to move up or down depending on the direction of rotation of the motor 4.
