Abstract: The workspace of the robot is the base for the mechanical synthesis and trajectory tracking. In the light of the characteristics of five-freedom, the polar coordinate searching method is used to determine the workspace of the fine tuning Stwewart platform for the large radio telescope. The effectiveness of the method is illustrated by an example. The result has laid a solid base for the feed trajectory tracking and the design of the fine tuning Stwewart platform for the large radio telescope.

Key words: robotics, mechatronics, Stewart platform, workspace
