This article describes a pitch motion technique for the IBM 7535 robot which expands its use in many applications. The concept, as illustrated in Fig. 1, consists of an aluminum yoke assembly 1 which is attached to the existing "Z" motion shaft 2 by utilizing the existing gripper mounting plate 3. Mounted within the yoke assembly 1 is a pneumatic rotary actuator 4 with a double end shaft. The double end shaft of the rotary actuator contains a hole through its center that permits pressurized air to enter the selected side of the actuator, causing it to rotate in the desired direction. To convey the pressurized air, a swivel fitting 5 is affixed to each end of the actuator shaft around the exterior of the yoke assembly.
