Computer Aided Geometric Approach for Parallel Mechanism

A computer-aided geometry approach for parallel robot mechanism is put forward.By using the geometric constraint and the dimension driving techniques in CAD software,the simulation mechanisms of the parallel robot are created,and the performance of the simulation mechanisms is consistent with the actual parallel robot.The results of computer simulation prove that the computer aided geometric approach is not only fairly quick and straightforward,but also has the advantages of accuracy and repeatability.It also can conducted type design and kinematic analysis of spatial parallel mechanisms without complicated analytics and program.
