Abstract
In late years marine resources development advances, and the sustained use of the marine resource attracts attention. The change prediction of the marine ecosystemic grasp and sea life is necessary for the sustained use, and it is said that an underwater robot is useful for this. In AUV(autonomous underwater vehicle), underwater photography or the investigation into quality of the water are carried out, but, among underwater robots, the collection method of the bottom of the sea creature is not established. A reason includes difficulty of the action control of the underwater robot having difficulty and a manipulator of the bottom of the sea creature collection. Therefore, in this study, I paid attention to an underwater vacuum cleaner and robot hand and evaluated development, the performance of the new sampling equipment which could supplement each bad point by each other's good points.
