Robot Fish Will Help Battle Pollution

High-tech 'carp' find chemical contaminants in Spanish harbor

(Newser) – Robots will soon be patrolling the harbor of Gijon, Spain, and if all goes well, the local sea life won't notice a thing, reports the Financial Times. The pollution-detecting bots cost $30,000 each and are modeled after carp, complete with shiny scales and an undulating swimming motion. "We are building on a design created by hundreds of millions of years’ worth of evolution which is incredibly energy efficient," said a researcher on the project.

The school of fish will roam the harbor, looking for pollutants and tracing them to their sources. When the 5-foot-long robo-fish return to their charging stations after 8 hours of swimming, they upload the data. "The hope is that this will prevent potentially hazardous discharges at sea," explained one of the professors who designed the creatures.

Created by engineers at the University of Essex, the robot fish measure about 8 feet long, can swim at roughly 2.24mph and feature real fish-like undulating action.   (rezadragon)

Isn't anyone worried we're just putting out $30,000 fish food for larger prey? I'm sure they have some sort of defense mechanism built for that, but what?
