A kinematically redundant robot, with more degrees of freedom than re-quired to complete a desired task, can be usefu1 because of its inherent kinematics flexibili-ty and dynamic performance. lt is very difficu1t, however, to implement optimal redun-dancy control, while simultaneously taking into account hath kinematics and dynamics.To realize dua1-optimization control, a new redundant robot mechanism with local degreesof freedom is introduced, and its kinematics and dynamics features are investigated. Simu-lation results demonstrate the effectiveness of the proPosed method.
