Outline of Final Research Achievements

In this research, adhesion and detachment mechanisms of geckos' foot hairs, which have a great ability of attachment and detachment to rough surfaces, have been investigated analytically and experimentally. Additionally, the applicability of the mechanisms to adhesive grip-and-release devices has been discussed. The hairs are assumed to be inclined beams, side surface of which adheres to the surface of a rigid, and the adhesion force and detachment process were analyzed. It was investigated that the control of normal and tangential forces was important for the detachment process. Attachment and detachment of the inclined adhesive beams were experimentally verified.
