The air-wall amphibious intelligent inspection UAV is a domestically pioneered cross‑domain platform for emergency surveys of bridges, tunnels and buildings. With four‑ducted power, it supports flight and wall‑adhesion via airflow‑generated negative pressure. Fused high-precision positioning and laser SLAM deliver centimeter-level tracking for open or confined spaces. It surveys high-risk inaccessible zones, avoiding human risks and boosting emergency response efficiency.
