The underwater docking technology of AUVs has long been a research hotspot at home and abroad. In the induction and analysis of AUV underwater docking technology at home and abroad,such as underwater box(cage)docking,robot or carrier-assisted docking,pole guidance docking,platform blocking cable docking and bell-mouth guidance docking, the implementation methods and structural principles of various AUV docking technologies at home and abroad are introduced,as well as the development status and development trends of docking technology. In light of the widely used bell-mouth guidance docking method,a submerged docking system for heavy-duty AUVs is introduced in detail. The experiment proves that this system has strong modularity and low requirements for roll attitude. It is suitable for AUVs of various sizes,and the docking success rate of the docking system is high. The findings of this study can provide useful references for the future development of AUV underwater docking technology.
