Robotic fish with flapping fins and tails have been programmed to swim in a school by researchers at the University of Washington in Seattle. They say that artificial fish with group behavior could track marine pollutants or wildlife such as whales. "With a group of vehicles you can get more data collection at the same time than with just one. You get better spatial distribution and cover more area," says Kristi Morgansen, a roboticist at the University of Washington in Seattle, US. (source: uwnews.org)
