Design of underwater robot system for sea cucumber fishing

Abstract

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 anticollision 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. Adaptive sliding mode control algorithm is used for positioning control of underwater vehicles to verify the effectiveness of system design.
