Abstract:In view of the present situation and application field of underwater robots, a new type of pneumatic controlled underwater glider was presented. The glider is controlled by high pressure air, and has the advantages of simple structure, low cost, reliable control, quick response, low energy consumption, long operation time which is suitable for fault detection of underwater, deep water sampling, aquaculture and other civilian areas. Through key component simulation analysis, it can provide important theoretical support for the pressure resistance test, structural optimization of relevant parts, and related experiments.
