U-CAT is autonomous, so it doesn't require a control cable that could get snagged or tangled

The U-CAT has an onboard video camera, which records video that can later be used to visually map out the inside of the shipwreck
Plans call for the U-CAT technology to be tested at underwater archeological sites in the Mediterranean Sea and the Baltic Sea
When was the last time you heard about a sea turtle getting stuck in a shipwreck? Never, that's when. Although that's partly because stuck turtles rarely make the news, it's also due to the fact that they're relatively small and highly maneuverable. With that in mind, the European Union-funded ARROWS project has created U-CAT – a prototype robotic sunken-ship-exploring sea turtle.
