TL;DR: In this paper , a low-cost underwater vehicle (ROV/AUV) for inspection and exploration of seabed and dams can replace the human being in this task and avoid emptying for maintenance work.
Abstract: Underwater vehicles are of great interest in seabed inspection tasks, nevertheless dams, which required complete emptying to inspect their walls, or else call a professional diver which is of great risk to its life given the marine currents existing below. As a result, designing an underwater vehicle (ROV/AUV: Remotely Operated Vehicle/Autonomous Underwater Vehicle) for the inspection and exploration of seabed and dams can replace the human being in this task and avoid emptying for maintenance work. In this article we will present a design of a low-cost ROV for observation based on the various existing underwater robots. A modeling part and numerical calculation approach for determining the differents coefficients are presented at the end.
TL;DR: In this article, the authors investigated the use of commercial modems mounted in a short-baseline configuration on an autonomous surface craft (ASC) for tracking other marine vehicles, which can be transmitted at a much higher rate than standard data packets.

TL;DR: In the new algorithm, a new fusion strategy is put forward to improve the fusion efficiency and a comprehensive evaluation function is designed according to principles of energy, time and security.
Abstract: The global path planning is one of key technologies of autonomous underwater vehicle's intelligent control. For the problems as low efficiency of searching optimal solution and insufficient objectives decision in path planning in three-dimensional environment, the rule of resistance and velocity is obtained first, then a new hybrid based on genetic-ant algorithm is proposed. In the new algorithm, a new fusion strategy is put forward to improve the fusion efficiency and a comprehensive evaluation function is designed according to principles of energy, time and security. Furthermore, a method to determine the optimal path is presented by selecting the optimal paths corresponding to different velocity values. The simulation results in three-dimensional environment show that the new algorithm can converge to the optimal solution in a short time and the method to find the optimal path is feasible.
