Abstract
This paper describes wall-climbing robot based on adhesion mechanism of ants. Adhesive pads which are similar to adhesive organs of ants were fabricated using micro fabrication techniques. In order to adhere the pad to a vertical wall, a small amount of liquid was supplied to the surface of the adhesive pad through micro channels using a micro pump. Tangential adhesive forces between the adhesive pad and a glass surface were measured. Furthermore, a hexapod robot that walks in the same gait as that of an actual ant was fabricated and the adhesive pads were integrated in each foot of the robot. The robot successfully adhered on a vertical glass surface.
