In this paper, a motion control for redundant manipulator based on observer is proposed. In conventional control for redundant manipulator, the pseudo inverse matrix and null space vector of Jacobian matrix are used for the end-effector motion control and configuration control respectively. However the calculation of such motion controller becomes more complicated as the number of the degree-of-freedom increases. In the proposed motion control, the null space motion controller is combined with workspace motion controller by using the robust control technique which is observer based one. Accordingly the design process and the total calculation of the motion controller is much simplified, and our approach realize the null space effects without much effort to calculate the null space term (I-J+J). The validity of the proposed method is confirmed by the several numerical results in the 5link planar redundant manipulator.
