Abstract
This paper is concerned with the development of the medical micro robot, Kinetic characteristics of a novel type micro robot with micro swimming mechanism is investigated for medical mahine with micro robots working in human blood vessels. It is composed of a small magnet attached to a polyethyleneterephthalate film. The alternating excitation magnetic field causes the magnet to oscillating motion due to magnetic torque. Conseqently, the micro robot may be propelled by waves traveling along the polyethyleneterephthalate film. The propelling velocity depends on the excitation frequency and dimension of the polyethyleneterephthalate film. The effect of wave form of the input electric current on the propelling velocity is also studied.
