The goal of this research is to develop an functional adhesive robot skin with micro suction cups realizing two new functions:adaptive adhesion to rough/curved surface and anisotropic adhesion. Both functions are realized by integration of asymmetric micro cups. This structure can be applied to various robot mechanisms like robot hands and wall-climbing robot foots and so on as robot skin. This paper especially reports the concept of this research and fundamental characteristics of a new fabricated robot skin. In over micro scale world, experimentally the skin shows unprecedented characteristics, namely, high adhesion force even on rough surface and anisotropic adhesion force.
