Researchers at Israel’s Ben-Gurion University have built a self-propelled fish tank that goldfish inside the tank can drive around on land. The tank has wheels, sensors, and a camera that track the fish’s movement, moving the ‘car’ in the direction the fish is swimming in.
Ten fish were trained to ‘drive’ the tank by putting visual targets around the room and rewarding the fish with food when they reached them. The team says that several of the fish cut down the amount of time it took them to reach a target from 30 minutes to under one minute during the experiment.
