Outline of Final Research Achievements

This work focused on development of a system to perform long-term, wide-area, and dense observation of seafloor environment based on collaboration of autonomous underwater vehicles (AUVs) and a seafloor station. Autonomous docking method based on acoustic and optical information was developed. A non-contact power charging method suitable for sea water was also developed. The methods were implemented in existing platforms to verify the performance through tank and sea experiments. The method has wide range of applications, such as resource survey, fisheries, facility maintenance, search and rescue, as well as sciences like biology, geology, and archaeology.
