Abstract

A test head manipulator system comprising a base structure, a main arm unit configured to support a test head and to be moved relative to the base structure, an actuator having a range of motion of L, and an enhancement mechanism positioned between the main arm unit and the actuator and configured such that movement of the actuator a first distance causes the main arm unit to move a second distance that is greater than the first distance. Additionally, a fluid control system for controlling a test head manipulator system. The pneumatic control system includes a regulator configured to controllably provide an output pressure to the main fluid actuator, and a second fluidly controlled actuator configured to adjust the regulator to modify the output pressure provided to the main fluid actuator. The second actuator is configured to be positively positioned in at least four operating modes with each operating mode causing the regulator to provide a different output pressure to the main fluid actuator.
