The Spanish port of Gijon is about to get a school of robotic fish who's mandate will be to detect pollutants from ships and outflows of sewers and industries. The robots are designed to swim like fish because the motion uses less energy than propeller drives “The design of fish which nature has produced is a very energy-efficient one,” says Rory Doyle, a researcher working on the project. “The fish's efficiency is created by hundreds of millions of years' of evolution. Submarines come nowhere near it.” The 1.5 metre long robots will be manufactured by the University of Essex and are expected to be deployed within 18 months.
