Could Robot Fish Lead Gulf Fish To Safety?

A robotic fish that is able to lead schools of real fish is under development by Maurizio Porfiri, an assistant professor at the Polytechnic Institute of New York University.

(Robot fish is a true leader)

How could a robot fish possibly act in a way to lead flesh-and-blood fish schools? It turns out that leader fish have definable characteristics:

Dr. Porfiri chose to start with the bait fish swimming in his tanks because their information-sharing is particularly rich: They make their decision on whether to school based upon what they see and the flow that they feel, which can be studied using fluid dynamics. Fish leaders, according to biologists’ published literature and Dr. Porfiri’s observations, beat their tails faster, mill about and accelerate to gain attention, gather a school and lead it.

Using a shallow, donut-shaped tank and cameras, the NYU-Poly team began a mathematical journey into fish schooling in one-dimensional environments. They recently reported their results from this study in the Journal of the Royal Society Interface. Meanwhile, they built silent, remotely controlled, fish-like robotic swimmers that fit in the palm of a hand. These first robots can “swim” along a plane; the next step is to create robots that can dive and surface.

To engage live shoal mates, Dr. Porfiri wanted to give the robot other fish qualities. Foremost, it would have to swim silently, and its locomotion would have to closely match that of live fish. To achieve these goals, he employed ionic polymers that swell and shrink in response to electrical stimulation from a battery, propelling the robot.
