swim like tuna, accelerate like pike and navigate like eel -- but
the new fish in the tanks of the London Aquarium are actually
The world's first ever
autonomously controlled fish made a splash at the
London Aquarium this week. The
three robotic fish, which are about the size of carp, use sensors to
navigate round the place and can therefore avoid the other (real)
fish they share a tank with.
The scientists at Essex University, who spent three years developing
the droids, say that because the robots' undulating movements are so
realistic, visitors assume the fish are real. Of course, as the fish
have shiny metallic scales and a battery power of five hours,
visitors would have to be pretty slow to not realize they are
looking at robots. To see if you can tell the difference take a look
BBC video of the robo-fish swimming
