ABSTRACT:
Apparatus for a dual powered actuator system. The system comprises a support member supporting an article in movement along a first direction and a second direction. A precision actuator is coupled with the support member and responsive to an input signal to selectively move the support member. A fluid actuator is also coupled with the support member to selectively move the support member. An active fluid regulator provides a first pressure to the fluid actuator in the first direction of the support member and a second pressure to the fluid actuator in the second direction of the support member, wherein the first and second pressures are different. A controller activates the active fluid regulator and the precision actuator.
