Abstract
A class of parallel manipulators known as rotary humanoid wrist (RHW), which is actuated by six circular motors on the circular base and dose not involve any prismatic joint, is analyzed based on screw theory. Model of RHW is build by using simulink tools with constant length limbs. The mobility of RHW is analyzed and the optimal combination of the main parameters for maximizing the workspace volume of RHW is also given.
