In recent years, skill preservation of an expert has been a serious problem in the medical or production fields. If digital skill preservation like a bilateral database is attained, it may become an innovative solution of the above problem. In this paper, abstraction and reproduction methods of force sensation from the real environment by bilateral control, and reconstruction method of the real environment are proposed. In the abstraction mode, a master-slave system is composed and the law of action and reaction is attained by bilateral control. We succeeded in realization of a vivid sensation of touch for bilateral robot system. Force and position information of both of master and slave systems is calculated and obtained, being based on acceleration information. In the reconstruction mode, an environment model is reconstructed from the obtained data of the real environment. In the reproduction mode, only the master system is prepared. Human operates the master system and feels force sensation from the environmental model which is reconstructed in the reconstruction mode. As a result, the proposed system is able to store the real environment as a bilateral database. The experimental results show the viability of the proposed method.
