Description

technical field [0001] The invention relates to a robot and a use method thereof, in particular to an underwater robot for detecting dam cracks and a use method thereof, and belongs to the field of underwater robots. Background technique [0002] Intelligent underwater robot Autonomous Underwater Vehicle, AUV, as a key underwater technical equipment, has become a practical and effective development tool in the fields of marine civil, military and scientific research. role. [0003] In water conservancy projects, dams are a very common engineering project. Due to the different materials used in construction projects, there are many types of dams, such as concrete dams, dry stone dams, earth-rock dams, earth dams, etc. Due to construction costs and geographical characteristics Compared with other types of dams, earth dams are relatively more, because the construction is easy and the cost is low. In many places, local materials can be used for construction, and the cycle is sh...
