Outline of Final Research Achievements

A grip-and-release mechanism of a beam structure has been investigated, which is used by geckos, insects, etc… to make a quick step on walls and ceilings with surface roughness. The beam is modeled as an elastic beam which has a root angle. The adhesion gripping force is theoretically investigate and compared with experiments. The grip-and-release devices with the multi-beam structure are made in the several ways. One of the ways is the stack of the comb structure. The device with small size of the beam can be successfully made and its performance is investigated as the grip-and-release device.
