Essex series robotic fish

These are Essex autonomous robotic fish tested in a public fish tank in the London Aquarium. The video was captured during preparations for unveiling the World's first autonomous robotic fish in 2006. It was reported by BBC and other news outlets. There are three motors on the tail joint. The skin is cosmetic and water flooded. The various models are labelled G6 , G8, andG9. This video shows how a "fish" detects the tank wall and other "fish" by IR sensors and changes its path to avoid collision.
