TL;DR: In this paper, two tether mooring type of underwater vehicles, Anchor Diver I and Anchor diver II, were introduced for long-term ocean survey and ROV (Remotely Operated Vehicles) which moves with a principle similar to flying a kite in the sky.
Abstract: 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.

TL;DR: In this paper, an AUV AQUA EXPLORER 2 (AE2) is used to inspect buried underwater cables and to survey the seafloor, and two sea tests were successfully performed.
Abstract: KDD has developed an Autonomous Underwater Vehicle (AUV) AQUA EXPLORER 2 (AE2), the primary mission of which is to inspect buried underwater cables and to survey the seafloor. As AE2 has no tether cables between the vehicle and mother vessel, no large onboard equipment such as cable handling drums are needed. AE2 can therefore be operated from a small vessel, which drastically lowers the operation cost. AE2 communicates with the mother vessel through acoustic links. The onboard operator can monitor the status of the vehicle and the image of the seafloor through the acoustic link, and also can control the vehicle. Two sea tests were successfully performed. In these sea tests, AE2 succeeded in tracking an actual underwater cable laid in the Pacific Ocean. AE2 was also used to survey the seafloor for the construction of a new optical telecommunication cable system surrounding Japan. AE2 is also expected to be used in various underwater inspections other than cable inspection. This paper summarizes AE2 equipment and operation and also describes results of sea tests.

TL;DR: A guidance system of the autonomous underwater vehicle "DeepC" in special situations when one or more objects interfere with the planned route of a mission is described.
Abstract: This article describes a guidance system of the autonomous underwater vehicle "DeepC" [ATLAS ELECTRONIK, 2005] in special situations. A special situation occurs when one or more objects interfere with the planned route of a mission. The possible reactions are evasion or identification of the objects. The paper presents these two tasks in overview. The special demands challenges of the underwater environment, computer parameters, sensors and the maneuverability of the vehicle are considered in the selection and development of the required strategies. Such challenges include the sea current, maneuver in the 3-D space and the limited perceptive faculty of the sonar.

TL;DR: The general design approach used to meet the operational requirements of the ARCS (Autonomous Remotely Controlled Submersible) is reviewed, and the types of problems encountered during implementation and preliminary testing are discussed.
Abstract: The central control computer of the ARCS (Autonomous Remotely Controlled Submersible) consists of three microprocessors residing on a common bus and communicating with each other via shared memory. This paper will review the general design approach used to meet the operational requirements of the vehicle, and discuss the types of problems encountered during implementation and preliminary testing.
