As Unmanned Underwater Vehicles become better and use mimicked techniques, which resemble sea life fluidity of motion it will be much easier to disguise them and virtually impossible to tell the difference. Simply paint a couple of eyes on them and paint them to look just like a fish, shark, whale or dolphin and let them swim a few meters away from you and you will not be able to know what is real.
These robotic fish, which Universities, US Navy, Researchers and Oceanographers are making, now will have many uses. They can patrol underwater pipelines, cables, bridge structures, piers, docks, shipyards and Earthquake Faults or perhaps even Underwater Volcanic Activities. They might also be incorporated into underwater sensors for Tsunami, by swimming quickly to the surface to contact the satellite, resting dormant at the bottom of the ocean floor until needed. Then they can return to the oceans floor again to conserve energy. These sensors will also be able to detect and protect our coastlines from underwater threats from hostile nation submarines, which wish us ill or are testing our abilities to catch them and then perhaps saving that information for some devious future endeavor.
Robotic Fish, which mimic sea life, is a helpful technology to blend into the background of our vast oceans so we can better understand the planet, fishing dead zones, needs of other species and protection of the American People.
RoboTuna Project is real and these fish are really here. The future of virtual fish is now.
