U-CAT’s locomotion principle is similar to sea turtles. Independently driven four flippers make the robot highly maneuverable; it can swim forward and backward, up and down and turn on spot in all directions. Maneuverability is a desirable feature when inspecting confined spaces such as shipwrecks. The robot carries an onboard camera and the video footage can be later used to reconstruct the underwater site.
