Review of Path Planning for Autonomous Underwater Vehicles

An autonomous underwater vehicle (AUV) is an important tool for the exploration and development of marine resources. Path planning plays an important role in the correct navigation and avoidance of obstacles by underwater robots in the sea. Firstly, according to different marine environmental conditions, AUV path planning is classified into two types. Then, the related algorithms of global path planning and local path planning are reviewed, and the key technologies, development status, advantages and disadvantages of related algorithms are combed. Finally, the development direction of the AUV in complex environment is prospected.
