Workspace study of the parallel manipulator 6-SPS

The workspace of parallel manipulator 6-SPS is studied in this paper. By means of the algorithm of mathematical analysis,the working envelopes and the reachable spaces with known structural parameters can be calculated accurately and rapidly. The influence of the structural parameters on the working envelopes is explored. Some regular variations of significance are found. These results are significant for the designing and usage of the parallel manipulator.
