The UAV spraying system launched by E-HAWK Technology is equipped with an independently developed high-precision flow control system and AI visual recognition module. Featuring a hexacopter propulsion layout, the UAV has a maximum payload of 15 kg and can carry various types of paint spray guns. It achieves centimeter-level positioning accuracy with LiDAR and Beidou positioning.

During operation, the UAV automatically plans the optimal spraying path based on the pre-imported 3D building model, and precisely controls the spraying flow and distance (maintaining 30–50 cm from the curtain wall surface), ensuring the coating thickness error is controlled within ±50 μm
