Would be smugglers and terrorists hoping to sneak drugs and weapons into the country hidden aboard vessels had better think again, for their plans will soon be rumbled by US government’s latest secret weapon – robotic fish. Modeled on the vastly under-rated tuna fish – one of the fastest and most maneuverable of all the creatures of the deep – the newly developed BIOswimmer robofish will be able to search and inspect the hulls of ships, and even the ocean floor should the bad guys attempt to ditch their contraband overboard. The BIOSwimmer is designed to operate in the harshest of environments, featuring a flexible aft section, plus numerous fins in the most appropriate positions to ensure maximum maneuverability. Researchers at the Department of Homeland Security’s Science and Technology Directorate said that the BIOSwimmer is a vast improvement of current underwater robots, which are plagued by maneuverability and propulsion problems. As well as being able to scan the hull of ships, the BIOSwimmer is also said to be nimble enough to squeeze into the most hard-to-reach places, such as flooded bilges and tanks, which are some of the favorite hiding places of smugglers.
