See moreAn autonomous crawler robot inspects cracks in tunnel walls. Equipped with AI sensors, it adjusts its speed based on the severity of damage detected. To capture clear images, the robot slows down when encountering significant surface damage. The manipulator arm takes pictures from various angles to minimize distortion. After scanning the entire concrete wall, all images are wirelessly transmitted to a computer with a user-friendly program for 3D reconstruction of the surface. This 3D model is then integrated with AI-based damage detection results to pinpoint the exact size and location of the cracks.
