The underwater robot was born in the second half of the 20th century. It is an extreme operation robot that works underwater. It can dive into the water instead of people to complete certain operations. It is mainly used in marine rescue, underwater survey, exploration and entertainment. Due to the harsh and dangerous underwater environment and the limited depth of human diving, underwater robots are increasingly becoming an important tool for the development of the ocean.
