Autonomous Urban Pipeline Repair Robot Swarm PipeBot Deployed in Tokyo: Autonomous Detection and Repair of Pipe Cracks in Underground Networks

The Tokyo Waterworks Bureau announced the deployment of the PipeBot autonomous pipeline repair robot swarm on October 8. The system consists of 100 micro-robots measuring 8 centimeters in diameter, capable of autonomous movement, defect detection, and repair within underground water supply pipelines with diameters of 20 centimeters or larger.

Each PipeBot is equipped with ultrasonic flaw detection sensors and a micro-camera capable of detecting pipe cracks as small as 0.1 millimeters. Upon discovering a crack, the robot releases a fast-curing sealant from its internal repair material reservoir to patch the crack from inside. This "endoscopic" repair method eliminates the need for excavation, reducing repair costs by 80%.

In three months of deployment, PipeBot has inspected 240 kilometers of water supply pipelines across Tokyo, discovering and repairing 1,200 micro-cracks and reducing pipeline leakage from 8% to 2%. The Tokyo Waterworks Bureau estimates that PipeBot can save approximately 15 million cubic meters of water annually. The system is being expanded to Osaka and Nagoya.
