Research Abstract & Technology Focus

Maintaining mechanical stability and achieving precise motion control on cylindrical surfaces remain critical challenges for underwater jacket cleaning robots. To address these issues, a systematic mechanical model is initially established for a standard column (diameter 2000 mm, inclination angle 90°) to determine stable climbing conditions. By neglecting equivalent gravity, the critical constraint relationships between adhesion and propulsion forces are derived. Subsequent open-loop maneuvering simulations, conducted via a six-degree-of-freedom dynamic model in MATLAB/Simulink, reveal that the robot achieves a straight-line speed of 0.233–1.601 BL/s and a maximum steady-state thrust of ~80 N at rotational speeds between 500 and 3000 rpm, and this thrust level corresponds to a required maximum adhesion force of approximately 106.4 N. To enable autonomous navigation, a closed-loop control system is developed for two-dimensional waypoint tracking, integrating line-of-sight (LOS) guidance, a waypoint switching radius strategy, and a proportional-derivative (PD) controller. Simulation results verify that the robot successfully navigates through five sequential turning waypoints under operational constraints, maintaining well-converged position and heading errors, with the maximum heading deviation controlled within ±5°. All simulation validations in this study are completed through numerical simulations in the MATLAB/Simulink environment. These findings offer a practical reference and theoretical foundation for the autonomous control and reliable deployment of underwater cleaning robots.
