"Biologists from the University of Leeds have built a computer-controlled replica of a three-spined stickleback fish to study how the behavior of individual fish might influence the movement of others. The so-called 'Robofish' was able to recruit single fish into a group, and cause fish in groups of up to ten to turn in the same direction as itself. The researchers claim that Robofish is the first robotic fish to 'interact convincingly' with a school of fish and convince the whole group to make a sharp turn."
