The observation and exploration of the seabed urgently requires the appearance of large-scale and long-term observation platforms. The subsea AUV has three main points: a structure that suitable for the mobility in the seabed, an intelligent motion performance that adapts to the complex environment of the seabed, and the underwater acoustic communication and positioning technology that adapts to the seabed. In this paper, the development and evolution of subsea AUV is analyzed, the key technical challenges of underwater AUVs are summarized, and corresponding solutions for underwater AUV hydrodynamic shape optimization technology, intelligent motion control technology, underwater acoustic communication and positioning navigation technology, and underwater connection and charging technology are provided. Finally, a study case of Autonomous Underwater Helicopter is given, to provide a solution for subsea AUV. This paper provides guidance for the development of subsea AUV, as well as ocean observation and exploration technology.
