Brief Analysis of Underwater Movements of Spherical Robot

Abstract

Underwater robot has become an important tool for people to understand, develop and utilize the ocean. At present, thousands of underwater robots have been developed to satisfy the requirement of underwater tasks and many researchers pay more attention on the underwater robots. This paper uses CFD to simulate the horizontal motion, downward motion and rotary motion of the spherical underwater robot to analyze the influence of spherical robot underwater structure on velocity and pressure, which provides the basic data of underwater motion of the robot and lays the foundation for optimizing the control method of the robot.
