A wheeled robot dog was conducting patrol inspections at the construction site of the Jinggangshan tunnel on the Chang-Gan high-speed ​​railway.

The robot dog can enter high-risk areas, such as areas with piles of crushed stone caused by tunnel blasting and steep slopes. They are capable of performing tasks such as safety patrols, identifying surrounding rock formations, cross-sectional scanning, and environmental monitoring, and capable of responding accurately to complex geological challenges.

The Jinggangshan Tunnel, the longest tunnel on the entire Changchun-Gan High-Speed ​​Railway, is located in the heart of the Luoxiao Mountains. It is 14.116 kilometers long and faces extremely complex geological conditions.
