Goldfish are trained to 'drive' a robotic tank by scientists

Daily Mail - Science & tech

In one of the weirdest scientific experiments yet, goldfish have been trained to'drive' a robotic tank around a room. Scientists in Israel constructed a'fish operated vehicle' consisting of a water-filled tank, a camera and a computer on top of a set of wheels. In tests, the onboard camera and computer were able to detect the fish's position in real time and activate the vehicle motors to move the vehicle in the same direction. Six goldfish were successfully trained to use the bizarre device and managed to find their way around the small room towards a food reward. The results suggest that fish can adjust their navigation skills'to a wholly different terrestrial environment', according to the researchers.
