The effects of fluid viscosity on a swimming magnetic micro-robot are studied experimentally. The micro-robots are composed of an annular neodymium permanent magnet and a polyethyleneterephthalate film. The micro swimming robot without the wire for supplying the energy is driven by the alternating magnetic field. The driving mechanism of the micro swimming robot utilizes the hydrodynamics of swimming uniflagellar micro-organism. Test liquids used in the experiment are water and glycerine. Locomotive characteristics of the swimming robot are analyzed by a high speed video camera system. Locomotive velocities of the robot in two diffent liquids are revealed.
