ABSTRACT:
A robotic manipulator for supporting a tool or workpiece, the manipulator including at least one rotary linear actuator adapted to be supported by a base and providing for controlled movement of a manipulator link with two degrees of freedom. The robotic manipulator includes a link assembly having one end spherically joined to a movable member for supporting the movable member, the movable member being adapted to support a tool or workpiece. The link assembly is articulated, and the opposite end of the link assembly is supported by a rotary linear actuator for linear movement in a direction transverse to a longitudinal axis of the opposite end of the link assembly and for rotational movement about the axis defined by that linear movement.
