Abstract
The goal of this paper is to propose mechanism of locomotion for micro robot moving in human body and to evaluate their propulsion. In this paper, we poposed three types of mechanism: drill type, vibration type, and liquid pressure type. The drill type uses a drill driven by a D. C. motor. The vibration type moves according to a movement of hair caused by a vibration motor. The liquid pressure type is driven by a movement of a syringe and a piston. We measured propulsion of them and concluded that the drill type and the liquid pressure type are more hopeful than the vibration type.
