A motion copying system is important to preserve skills of expert engineers. This paper proposes advanced motion copying system of multi degree-of-freedom. The multi in this paper means infinite number degree-offreedom of system and human. The proposed method saves virtual force and position informations of the virtual systems. If the infinite number person saves independent motions of the infinite number virtual systems, the proposed method realizes infinite number advanced motions. The proposed method allows for loading the best or new skills because we can consider the advantage of each independent motion. The experimental results show the viability of the proposed method.
