Influence coefficient matrix changes with configuration of mechanism. The paper presented a group of mechanisms including 121 mechanisms by changing their dimensions, then studied performance index of kinematics and dynamics for 6-HURU parallel robot mechanism with different dimensions by both of the first and second order influence coefficient matrix of different sample points in every mechanism's workspace. It breaks through the restrictions due to considering only the first order influence coefficient matrix in the past. Furthermore, the paper also discussed the performance differences of mechanism with different dimensions by the atlas of global performance index and validated them. The paper’s contents offer the basis for designing parallel robot mechanism of this type with good performance.
