Verification of Quantitative Assessment of Wall Thickness Reduction in Sewers Due to Corrosion Using AI and Robots

AI Summary (NQ-processed)

NTT Docomo Solutions, in partnership with the Kyoto Prefectural Basin Sewerage Office and Tmsuk Co., Ltd., conducted a joint verification from April to December 2025. By using a LiDAR-equipped robot and a proprietary AI, they successfully quantified and visualized the depth and extent of wall thickness reduction caused by corrosion in a section of Kyoto's sewer system. The initiative aims to improve the accuracy of infrastructure maintenance and prioritize repairs for Japan's aging sewer network.
