Sea cucumber fishing is an important application of underwater robots. In order to realize the function of sea cucumber fishing, an underwater robot system for sea cucumber fishing is designed, which can reduce operation requirements and costs while realizing sea cucumber fishing. The overall system plan includes the design of subsystems such as power supply system, fishing system, transmission system, propulsion system, balance and positioning system, and anti-collision airbag. According to the actual needs of sea cucumber fishing, the mechanical structure and size of each subsystem are designed, and SolidWorks is used to complete the three-dimensional modeling of the overall system. The sliding mode control and adaptive sliding mode control algorithms are used to compare the positioning control effects of the underwater vehicle to verify the effectiveness of the system design.

海参捕捞是水下机器人的重要应用。为实现海参垂钓功能，设计了一种海参垂钓水下机器人系统，在实现海参垂钓的同时可以降低操作要求和成本。总体系统方案包括供电系统、钓鱼系统、传动系统、推进系统、平衡定位系统、防撞安全气囊等子系统的设计。根据海参捕捞的实际需要，设计了各个子系统的机械结构和尺寸，利用SolidWorks完成整个系统的三维建模。
