Development of Tether Mooring Type Underwater Robots: Anchor Diver I and II

Ocean survey is more difficult than land-based investigation, since the underwater vehicles are susceptible to being swept away by sea currents. Present study proposes a new concept of underwater vehicle, in which the robot is moored by a tether and utilizes the sea current for movement. Two tether mooring type of underwater vehicles, named “Anchor Diver I” and “Anchor Diver II”, will be introduced in this paper. Anchor Diver I is an AUV (Autonomous Underwater Vehicles) developed for long-term ocean survey and Anchor Diver II is a ROV (Remotely Operated Vehicles) which moves with a principle similar to flying a kite in the sky.
