The functions of tracked patrol robot and wheeled patrol robot are almost the same. For example, Huatong's wheeled patrol robot adopts a brand-new laser navigation scheme, which realizes 360-degree patrol coverage without dead ends through the combination of fully autonomous regular patrol, manual remote patrol, fixed-point specific patrol and linkage patrol. The special feature of crawler patrol robot is its crawler design, which is specially used in rough roads and other harsh working conditions, and has stronger obstacle-crossing ability. It can be used for patrol and inspection in oil production areas, underground mining areas and other scenes.
