In recent years, in order to improve the safety and stability of ships, anchoring robots have become a research hotspot in the marine field. In view of the many excellent properties of the Atlantic razor clam, this article will use it as a bionic object to construct an anchoring robot body that integrates the functions of excavation, anchoring and autonomous detachment. Firstly the current research status of mooring robots at home and abroad is explained. Secondly, the mechanical design of the anchoring robot imitating the Atlantic razor is explained in principle. Finally, it will focus on the control system of the mooring robot. Experimental results show that the control system can enable the anchoring robot to complete excavation, anchoring and autonomous detachment, and form a larger anchoring ratio.
