Fuel cell powered robotic fish (video)

The robot fish is not a new concept but this ‘creature’ is quite different because it is powered by a cyclindrical solid-polymer fuel cell called the Power Tube.

The robotic fish, developed at Osaka City University, has a length of 100 millimeters and can swim smoothly, almost like the real thing. It can also dive and rise by changing the center of gravity of its synchro device as you can see in the video below.

The purpose of creating the robot is for rescue work and future maritime research.
