This paper deals with the forward position analysis of an over-constrained 3-DOF parallel mechanism of 2-RTR&RSR.By using analytical method in the forward position analysis,sixteen order polynomial equation has been derived and gives the entire set of solutions for the forward position of the mechanism.The examples show the effectiveness of the proposed algorithm.
