The U-CAT robot will be driven by a quartet of flippers, allowing it to swim backward if required and of course, forward, not to mention going up and down and turn on the spot regardless of the direction. With such a high degree of maneuverability, it enables the U-CAT to explore small, confined spaces. This would definitely be safer for humans, since diving is still considered to be a highly expensive and time consuming method when exploring underwater sites including shipwrecks are concerned.
Taavi Salumäe, the designer of the U-CAT concept and researcher in Center for Biorobotics, Tallinn University of Technology, said, “U-CAT is specifically designed to meet the end-user requirements. Conventional underwater robots use propellers for locomotion. Fin propulsors of U-CAT can drive the robot in all directions without disturbing water and beating up silt from the bottom, which would decrease visibility inside the shipwreck.”
