Schools of fish follow the robot leader


Through a series of experiments, researchers from Polytechnic Institute of New York University (NYU-Poly) aimed to increase understanding of collective animal behavior, including learning how robots might someday steer fish away from environmental disasters.

Nature is a growing source of inspiration for engineers, and the researchers were intrigued to find that their biomimetic robotic fish could not only infiltrate and be accepted by the swimmers, but actually assume a leadership role.

In a paper published in the Journal of the Royal Society Interface, Stefano Marras, at the time a postdoctoral fellow in mechanical engineering at NYU-Poly, and Maurizio Porfiri, NYU-Poly associate professor of mechanical engineering, found conditions that induced golden shiners to follow in the wake of the biomimetic robot fish, taking advantage of the energy savings generated by the robot.
