Design and Implementation of Amphibious Robot for Subsea Cable Maintenance

Abstract

Due to the complex subsea environment and the effect of various submarine conditions, it is quite often that the subsea cables may be damaged easily. In this paper, an amphibious robot, a kind of remotely operated vehicle (ROV), for subsea cable maintenance is designed. The robot is able to work in two operation modes, which are floating mode and tracked crawling mode. The robot is also equipped with operating tools such as manipulator and shearing machine to repair the cables. Multiple sensors and navigator are applied for robot navigation to ensure the operation stability.
