Robot helps workers monitor trains

With the help of a six-legged robot, Liu Tianyu and his colleagues can easily finish collecting internal temperature data and check the safety status of high-speed train carriages as they come off the production line.

Liu, 40, head of the diagnostic team of CRRC Changchun Railway Vehicles Co in Changchun, Jilin province, developed the robot to improve their work process.

"The purpose of our team is to test the operating stability of each system of the high-speed trains and their final performance before leaving the factory," Liu said. "With the continuous advancement of technology in high-speed train applications, advanced digitalization and informationization methods must be combined with technological innovation."
