In the Abalone Fishing by spearing, fisheries normally sense the size of Abalone fish by looking from the ship. However, sometimes it is hard to sense. Therefore, we have been trying to develop a robot system, which is equipped with stereo camera set, to assist measuring the size of Abalone fish. The robot is a small size and it has 6 thrusters to achieve 5 D.O.F motion in underwater.
