Abstract
Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has been developing three autonomous underwater vehicles (AUVs). And one of them is "OTOHIME". The aim of this vehicle is to measures the amount of chemicals near the seafloor and observes the seafloor condition and topography. Although It is still in a developmental stage, it is soundly near completion because various tests are repeatedly conducted. In this paper, its outline and some key technologies are explained.
