Abstract: DSV (Deep-sea submersible vehicle)-specific tool-box is irreplaceable in the deep-sea resources exploitative activities. Considering the tool-box as an indivisible part of the DSV is one of significant factor of DSV principle design, which means that the deep-sea resources exploitation will be one of most important activities for the coming DSV. Based on the investigation of DSV Alvin of Woods Hole Oceanographic Institution, the USA, underwater manipulators, sensors, sampling devices, and relevant technology for our own DSV are investigated. And the selections and schematic designs for main parts of the tool-box are put forward as well.

Key words: Deep-sea technology, DSV, Sampling device, Tool-box, Underwater manipulator
