For robot arms, wrist mechanisms are important elements for handling ability. We have proposed a heavy-duty wrist mechanism with a large motion range named, "2-DOF Spherical Parallel (2DSP) mechanism." The 2DSP mechanism is driven by a 2-DOF spherical parallel mechanism and supported by a universal joint located at its center. In this paper, we propose a method to maximize workspace in avoidance of singularities or too small output torque. The test model was developed, and the feasibility of the proposed method was verified.
