In response to the efficient and safe cleaning needs of bulk cargo holds，starting from the analysis of the mechanical characteristics of the four‑wheel drive robot，key components of the robot were designed.A detailed analysis was conducted on the force and torque characteristics during the process of crawling through obtuse angled walls，reverse inclined surfaces，and obstacle crossing in cargo holds.A mechanical equilibrium equation was then constructed considering the friction force of the wheels and the magnetic adsorption force.Combined with the actual working conditions on site，the adsorption ability of the robot was analyzed and verified.A cargo hold water jet cleaning robot carrying an adaptive cleaning robotic arm is developed and applied on site.The results show that the safety factor of the developed cleaning robot is 1.98，indicating excellent wall attachment ability of the robot.During cleaning operations，the jet radius can reach 25 m at a rated pressure of 1 MPa.Compared with manual cleaning，the cleaning efficiency has been improved to 900 m2/h，and the cleaning time has been reduced by about 50%.The research results can provide reference for the application of automated cleaning of cargo holds in bulk carriers.
