U-CAT Turtle-bot Explores Shipwrecks

Nov-27-13 The U-CAT robot was developed to explore shipwrecks, where its small, turtle-inspired body can squeeze into places too tight or dangerous for humans to venture.

Instead of the typical propellers, the U-CAT is equipped a camera that collects footage of the wreck for later study and four flippers that allow it to move forward and backward as well as turn in place and hover. The choice of flippers was an important key in the development of the robot, because they enable it to move through the environment without disturbing the water and stirring up silt from the seabed, which would decrease visibility.
