Structure Improvement and Stability for an Amphibious Spherical Robot

摘要

This paper proposed a novel mechanical design method of stability system and structure improvement for the new underwater robot is discussed, and also describes the key technologies and methods in detail of the robot to achieve multiple degrees of freedom. The new robot has ability of adjusting direction and perform specific mission goals. The ANSYS water pressure test and resistance test were performed on the mechanical structure under water intent to evaluate the design rationality of the robot leg and the overall robot. The article also introduced the stability system of the underwater robot and the installation and control method of the servo motors. Finally, the speed and gait stability of the robot underwater and land are analyzed through lots of experiments.
