マンタ法によるサンゴ礁調査を支援する水中ロボットのためのレーザーにより水中での高度を計測して、それを維持するためのシステムの開発と基礎実験の結果について報告した。

Distribution map of the degree of coral has been created by Manta method to use coral conservation activities. The manta method is a survey method that divers investigate the degree of coral and whitening state while being towed to a boat. But the manta method makes great physical burden also underwater robot can substitute, and desirable underwater robot that can maintain an altitude between underwater robot and seabed. Therefore, we have developed the altitude maintenance system for underwater robot for the purpose of investigate by Manta method is described in this paper. The distance measuring method using the laser beams and a monocular camera with image processing is adopted reason that waters inhabiting coral is high transparency. The evaluation experiments in the pool with the system and underwater robots were confirmed to have sufficient accuracy for the assumed survey mission.
