Small fish robots, the size of a killifish – 5 cm long – are potentially in finding disaster victims in flooded areas, because of their ability to navigate narrow confines. Powering such robots, however, becomes a question, since the easiest answer – rechargeable batteries – has low energy density. The “Power Tube” we developed is a small and ultra-light passive-type polymer electrolyte fuel cell. Based on this fuel cell technology, we fabricated a 110 mm fish robot combining a drive, consisting of a DC motor and link, with a Power Tube having a hydrogen generator. We also fabricated an energy-efficient submersible fish robot with neodymium magnets and coil actuators, that methanol-fueled Power Tubes powered with a voltage booster.
