French company Segula Technologies is currently developing a drone designed for the inspection of railway tunnels. The drone will be able to perform autonomous inspections of power lines inside underground tunnels. It will also be able to record RGB and thermographic videos and collect information about environmental conditions in underground tunnels using on-board sensors. This will allow visual inspection technicians to carry out their work without having to go down into the tunnels, thus avoiding the inherent dangers. The thermographic camera will be able to detect potentially damaged hot spots on cables, and the RGB camera will be able to check for faults such as breaks or cracks in cables that may have overheated.
