Fish Follow Robot Impostor

It's a robot in fish's clothing.

A group of researchers from the Polytechnic Institute of New York University and the Istituto Superiore di Sanita in Rome showed for the first time that a robotic zebrafish attracts living fish, casing them to gather around it and shoal.

It may be possible to use similar robots in the future with other kinds of fish, to draw away pest species or save endangered ones by leading them out of danger. The results are being published in the journal Bioinspiration and Biomimetics.

Marizio Porfiri, who led the work, has loked at fish behavior in response to robots before. In February he built a robotic fish that generated a wake like a living one, attracting others into a school.
