A novel overconstrained 2-RRU&RSR parallel mechanism was proposed and analyzed. By vector method, the explicit equation of the inverse was gotten. Then, the overall Jacobin matrix of the parallel manipulator was established based on screw theory. Finally, the kinematic transmission performance of the mechanism was analyzed by defining transmission efficiency coefficient between limbs and some conclusions were given.
