Their research covers multiple aspects, including autonomous driving, autonomous obstacle avoidance, planning and navigation, and pattern recognition. USVs have been applied in various industries such as surveying and mapping. USVs often carry various measurement equipment to detect various parameters of the measured water area. USVs and their onboard measurement equipment are relatively expensive. Water surface launching and recovering devices are also used in the use of USVs.

[0003] By comparing a drone deployment and retrieval device with patent publication number CN222432539U, it was found that in this solution, the output of a first servo motor drives a support plate and a clamping mechanism to clamp the drone on the water surface.
