| Abstract: | The actuator singular configurations of three kinds of planar redundant parallel mechanisms(PRPR-2PRR,(PR)R-2PRR and 4-PRR) were discussed.Compared with planar non-redundant 3-PRR parallel mechanism,the methods and characteristics for different types of redundancy in eliminating singularity configurations of parallel mechanism were studied.The analytical results can be of great useful to the dimension synthesis,trajectory planning and control of redundant parallel mechanism. |
