Abstract：
 The present invention belongs to the field of industrial robot. The robot mechanism consists of one frame, one moving stage and four branches to connect the moving stage to the frame to form a parallel closed loop structure. Of the branches, each of two contains two single-freedom motion pairs and one ball articulation, and each of the other two contains one single-freedom motion pair and two ball articulations or one ball articulation and one Hooke. The four hinges between the branches and the moving stage and those between the branches and the frame are cross arranged. The present invention has the advantages of determinate motion mode, easy kinematics solution, high rigidity, high accuracy, low motion mass, high dynamic performance and simple structure.
