AUV Recovery Technology Development Based on Unmanned Surface Platform

The traditional construction methods involving carrying, distributing, recycling, positioning support, state monitoring, and energy supply for autonomous undersea vehicles (AUVs) via a specific support mothership are relatively expensive as well as low in efficiency. Therefore, various scientific research and engineering institutions have begun to study the use of unmanned surface vessels (USVs) for carrying AUVs and providing the necessary technical support. Automatic recovery technology for AUVs is crucial. Accordingly, the development of AUV recovery technology is first introduced herein. Then, AUV autonomous recovery methods based on USV platforms are summarized, including surface slide type, surface cabin dock type, and underwater docking station type. Finally, the key technologies of AUV autonomous recovery are analyzed, including the design of USV-integrated launch and recovery systems, AUV guidance capture devices, and cross-media collaborative control. Thus, this study aims to provide research ideas for breaking through key technologies, develop integrated surface unmanned platforms for AUV operational support and guarantee of AUV operation, improve AUV operational efficiency, and reduce construction risks and cost.
