Engineers at CNN have created a new generation of robotic fish . ' Robofish ' could be used to map the ocean floor , inspect submerged boats or pipes . MIT researchers built their first robotic fish , ` Most of the brains , the electronics , are embedded inside , '' in 1994 . At five to 18 inches , the new fish is much smaller than Robotuna and built from a single , soft polymer . New robofish are modeled after bass and trout and cost only a few hundred dollars .
