The underwater robot is a complex intelligent system, which can replace human beings to carry out underwater work in complex and hard environment. Underwater robot is a complex system integrating many disciplines, including mechanical, electronic, computer, fluid, structure, material and other disciplines, which has become the main tool in underwater observation, underwater archaeology, underwater search and rescue, aquaculture and other aspects. Through the underwater robot, we can use it in many ways, such as marine environment monitoring, seabed resource exploration, military application, etc., which can replace human beings to complete observation, camera, information collection and other work in the deep water environment. The underwater robot must face the complex marine environment, which requires its carrier to have a variety of high requirements, such as pressure resistance, water tightness and carrying capacity. Through high-quality carrier design, we can better improve the carrier's promotion efficiency and space operation ability. By establishing a perfect integrated motion control system, the underwater robot can realize behavior reflection and information control, which will improve the robot's motion control technology. First, this paper classifies the underwater vehicles. Then, the basic principle of the underwater vehicle is analyzed. Then, this paper designs the underwater vehicle. Finally, this paper analyzes the motion control structure.
