October 11. 2005 There may be a different fish to see for every day of the year at the London Aquarium at County Hall, but there's a new variety that has never swum any of the world's oceans. Since October 6 the Aquarium’s unique robotic fish has been swimming in a specially-designed tank. Three stunningly beautiful robotic fish have been created with jewel-bright scales and sinuous, astonishingly life-like movements. They have been produced by Professor Huosheng Hu and his human-centred robotics team of the Department of Computer Science at the University of Essex. Professor Hu's team have been working with the London Aquarium for three years to develop a biologically inspired robotic fish which mimic the undulating movement of nature's fish species – aiming for the speed of the tuna; the acceleration of a pike, and the navigating skill of the eel.
