This paper introduces our new AUV HATTORI and scanning sonar based terrain tracking algorithm implemented in the vehicle. The AUV HATTORI (Highly Agile Terrain Tracker for Ocean Research and Investigation) is a lightweight and low-cost testbed designed for rapid and efficient imaging of rugged seafloor, such as coral reefs. Most of current AUVs suitable for seafloor imaging are heavy and expensive,...
In order to get highly detailed information of seafloor with low-cost, the authors have been developing high speed autonomous underwater vehicle (AUV) using low cost scanning sonar. It is difficult to design the AUV navigation system functioning properly in various seafloor environment because the sonar echo levels from the seafloor are relatively weak and differ with the survey area. In this study,...
In recent years, many types of autonomous underwater vehicle AUV (Autonomous Underwater Vehicle) have been used in various surveys in water. Since AUV is operated and navigated autonomously without tether cable that connects its mother ship, we can save human resources in accordance with the operation, and also we have an advantage of not subject to the constraints of the mother ship with respect...
