BINO, short for Bearing Inspector for Narrow-space Observation, is a tethered Unmanned Aerial Vehicle (UAV) system designed to carry out the inspection of rail viaduct bearings in narrow and difficult to access environments. It negates the need for time-consuming and dangerous in-person human visual inspections and resolves existing operation constraints, while enhancing inspection quality and improving efficiency and safety.
