| Abstract: | A new type of spatial parallel manipulator with three degree of freedom is proposed.According to the theory of screw,the moving platform of the parallel manipulator is analyzed.The result shows the platform only realizes three-dimension shift.The position and velocity analytic equation are constructed based on the coordinate transformation,and the singularity analysis of the manipulator is done by the forward and the inverse Jacobian matrix. |
