[0002] An underwater unmanned submersible is an intelligent underwater navigation device, mainly used to replace divers or manned small submarines to perform high-risk underwater operations such as deep-sea exploration, rescue, and mine removal. It is also called a "diving robot" or "underwater robot". Unmanned submersibles are mainly used for operations and construction such as shipwreck salvage, deep-water exploration, and underwater cable laying.
