Autonomous underwater vehicles (AUVs) are indispensable tools for marine scientists to study the world's oceans. Depending on their missions, AUVs are equipped with advanced sensors (sonar, cameras, acoustic communication, bio-sensors), have on-board computers for data analysis (image analysis, data compression), and are capable of on-board decision making (resource planning, swarming). Since AUVs...
Today a large number of autonomous underwater vehicles (AUVs) are evaluated or operated all over the world. Most of them use their own control systems created by the vehicle's manufacturer or scientists of different research areas. The Fraunhofer Application Center System Technology currently owns three underwater vehicles (both AUVs and remotely operated vehicles, ROVs), a forth is under development...
Due to its significant potential applications, underwater chemical plume exploration and source localization via an autonomous underwater vehicle (AUV) is currently a hot subject both in AUV and oceanic engineering research communities. Chemical plume including buoyant stem and non-buoyant part such as deep-sea hydrothermal plume is a typical dynamic 3D feature in the ocean environment; therefore,...
Path planning is basis for any autonomous underwater vehicle to implement completely cruising in subsea environment and path tracking is important technology as well, especially for multi-AUV (Autonomous underwater vehicle) cruising with a fleet formate. In this paper, algorithms path planning and path tracking are addressed for an open frame AUV. Fast Marching algorithm is applied to solve problems...
In the past few years, there has been increasing interest in the use of the Arctic, both as an ocean waterway and as a source of natural resources and food. In support of these objectives, scientific studies and research to characterise the Arctic environment are being initiated. At the same time, northern nations have begun to collect the data that is necessary to assert their sovereignty claims...
