Robofish becomes school teacher

Researchers from the Polytechnic Institute of New York University (NYU-Poly) have created a robotic fish that can lead a school of real fish.

In a study to try to better understand collective animal behaviour, the team experimented with a robotic fish that could mimic the tail propulsion of a swimming fish.

By manipulating the tail beat frequencies and flow speeds of the biomimetic robot fish - leader fish beat their tails faster, while followers beat their tails slower - they were able to lead a school of golden shiners.
