A swimming micro fish robot whose size is as small as a killifish is useful to seek disaster victims in flood areas, because it can go into narrow spaces. However, in the case that rechargeable batteries are used for supplying electricity to the robot, the robot is not able to continue swimming for a long time because of low energy density of the batteries. Therefore, the authors developed a small and ultra-light passive-type polymer electrolyte fuel cell called "Power Tube". On the basis of this fuel cell technology, the authors created a small fish robot (total length: about 110 mm) by unifying a tail fin driving mechanism, which was composed of a small DC motor and a link, with a Power Tube including a hydrogen generator. The authors also created a low energy consumption micro fish robot with small neodymium magnet and coil actuators, to which two Power Tubes supplied electricity with the assistance of a voltage booster, using methanol as fuel.
