The paper proposes a construction method of bilateral system using redundant manipulator. In bilateral system, it is important that operation can be realized in narrow space and at remote plate. Then the master-slave robots with redundancy are convenient and needed to achieve the bilateral motion effectively. However, human operation will become difficult because of the multifunctional mechanism. Especially, operating the posture of redundant manipulator by human hand is so difficult because the manipulator redundancy enables to achieve infinite number of the manipulator posture. This paper focuses on a construction of bilateral system so that it assists the human operation by adjusting a configuration control of redundant manipulator. In particular, bilateral system utilizes visual information by cameras to recognize the target object of remote environment in slave. By using this camera information, the assist for the slave operation of redundant manipulator is realized without deteriorating the bilateral motion.
