| Abstract: | Using the Denavit-Hartenberg method,the kinematic equations are established for a new kind of three-DOF 3-PRRU parallel manipulator.the 64 Groups of the inverse position of the manipulator is obtained according to the inverse kinematics equations and numerical example is given with matlab.Through the Jacobian determinant,the singularity condition equations are gained and analyzed. |
