Reproduction of 2-DOF motion adapting to environmental angle change

Recently, technology which deals with tactile sense has attracted attention in various fields. In particular, researches about storing and reproducing human motion are one of important fields for the haptic technology. A motion-copying system is known as one of efficient methods to achieve storing and reproducing human motion. However, it is known that environmental condition change is serious problem for the motion-copying system. To resolve this problem, many methods have been proposed. However, most of them are not sufficient because these methods deal with only 1-DOF motion and they are for adapting only environmental position change. In this paper, a reproduction method adapting environmental angle change is proposed using 2-DOF system. Validity of the proposed method is confirmed by experiment. By the proposed method, adaptivity of the motion-copying system is improved.
