Abstract: This paper introduces the recovering system developed by us for the 1000-meter and 6000-meter untethered autonomous underwater vehicles(AUVs)which are two of the projects in the State High-tech863 Program. This recovering system can recover the underwater robots in a 4 grade sea condition without the help of specific surface supporting vessels.Two different recovering schemes and recovering units are represented according to surface supporting vessel, sea status,AUV and other conditions.Results of sea trials show that this recovering system is effective and reliable.
