Development of the robotics system to record crack in concrete structures

Abstract

In our research, we focus on the maintenance and inspection management of cracks which occurred in reinforced concrete slab. We proposed and developed a robotics system for inspection by short range visual observation on the basis of the conventional inspection method. We suggested a robot that can photograph the cracks with less than 0.15 [mm] width from the ground. We have developed two crawler robots with camera attachment for inspection. One robot photographs a detailed image of the cracks, and another one photographs the entire image of the RC slab. We create a damage report map that showing the damaged position of the crack. As a result, it was possible to improve the efficiency of inspection work with the robotics system.
