Recently, motion copying technologies are important elements in order to succeed production engineering of expert engineers. The paper proposes a novel motion copying system. The motion copying system consists of a motion saving system and motion loading system. The motion saving system saves motion of human operator by bilateral controller using a quarry matrix. On the contrary, the motion loading system is realized by virtual-world master system and real-world slave system. The motion loading system operates according to saved position and force information, and reproduces saved motion. The proposed method realizes that the reproduced position and force corresponds to saved position and force data. The paper confirms that the motion saving system and motion loading system normally operates. The motion copying system achieves copy of motion of human operator.
