Abstract
An embodiment of a system and method for moving an object in one axis includes one or more fluid inflatable containers which are arranged to transmit fluid pressure to a plunger, such that a flexible membrane of the fluid inflatable container engages with the plunger and forms a rolling lobe in response to changes in volume. The fluid inflatable containers are enclosed within an enclosure or drum, and a shaft runs axially through the center of the enclosure. The system further includes one or more control valves operably connected to the one or more fluid inflatable containers for controlling the volume of fluid in the one or more containers. By changing the volume of fluid in the one or more containers the object is moved. In an embodiment an arced plunger is used to assist in creating the rolling lobe.
