Something Fishy
New to the London Aquarium: a robotic carp

Swimming alongside its living counterparts at the London Aquarium, the new 20-inch-long "robo-carp" uses artificial intelligence and an infared sensor inside its mouth to detect and avoid obstacles. Like real fish, it generates forward thrust by undulating its tail. Engineered by scientists at the University of Essex in England, the battered-operated fish serves as a decorative prototype for future autonomous underwater vehicles that will be tasked with arduous missions, such as sniffing out underwater and leaky oil pipes.
