This paper aims at analyzing dynamic characteristics of human arm movements from the viewpoint of Rie-manni an distance. In order to evaluate the amount of inertia-induced movement of a multi-joint arm, a measure called inertia-induced measure is developed. By applying the measure to actual human reaching, it is shown that the smooth reaching tends to be closer to the inertia-induced movement than the clumsy reaching. From this observation, it is sug-gested that humans use their own inertia properties efficiently in smooth reaching.

This paper aims at generating desired feedforward torque for a specified motion by reuse of time-series to rque data acquired by the iterative learning control. The suggested method named motion-scalet rans for mation realizes a motion to an arbitrarily specified posture of a two-DOF planar robot arm on the basis of arithmetical operations of time-series to rque of only four motions. The algorism is theoretically presented, and the effectiveness is confirmed in experiments. It is shown by the experimental results that the trajectory tracking error so fangular velocities by the motion-scalet rans formationt end to be smaller than those by the computed to rque method.
