Transmission Line Inspection Robot takes the ground line of the transmission line as the operation path and adopts the composition of a double-armed walking motion platform and various types of high-precision detection systems to conduct fine inspections of transmission line towers, insulators, gold tools and the whole process state of the transmission line channel in real time, and automatically collects inspection data and real-time background intelligent analysis, management and alarms to provide reliable diagnostic results for the operation and maintenance of the line and achieve predictive maintenance, prevention of problems before they occur. The transmission line inspection robot has greatly improved the safety, timeliness and accuracy of line troubleshooting and operation and maintenance.
