There is a great deal of research into operating autonomous underwater vehicles(AUVs) from unmanned surface vehicles(USVs) to perform underwater exploration missions in a wide range of waters and at low cost without putting in manpower. For this purpose, it is essential to use a system for automatic launching and recovering of AUVs from the USV. This study deals with the development of a launch and recovery system for the launch and recovery of autonomous underwater vehicles on the bottom of an unmanned surface vehicle. The mechanical part of the LARS can be designed using various mechanisms, and in this study, the sarrus mechanism is applied to implement the up and down movement of the LARS. Structural analysis of the designed LARS system was performed and it was confirmed that there is no problem with the operation in the marine environment. In addition, a hydraulic system was applied to operate the LARS system, and the overall hydraulic system was designed by calculating the capacity of each hydraulic cylinder. The electrical and electronic system for operating the hydraulic system was designed.
