The U.S. Navy has developed an unmanned underwater robot that looks and moves like a blue fin tuna.
The robot is a result of Project Silent Nemo, which tested the prototype at Joint Expeditionary Base Little Creek in Virginia on Thursday. The fish can be controlled with a joystick or be programmed to swim on its own.
Project engineers tell the Virginian-Pilot newspaper that the model is attractive because, by mimicking the evolved motions of a real fish rather than propelling itself through the water with a propeller like most submersibles, Nemo moves extremely quietly. The hope is Nemo will be able to sneak into enemy waters more effectively and patrol undetected in American waters.
