摘要：
In this paper we present a conceptual design for a powerful hydraulic micro actuator that provides three degrees of freedom motion. The actuator consists of three hydraulic pumps and three semi-flexible spherical pressure vessels. The spheres are configured like a 3D Stewart platform mechanism, where the tip of the actuator is attached to the upper plate of the mechanism. By controlling the internal pressure, the spheres' radii are adjusted. The actuator provides micro positioning mechanism using standard hydraulic pumps, and therefore the mechanism is a cost effective, accurate and powerful positioning solution for a 3D micro actuator.
