Bullet train maintenance goes robotech

(ECNS)--Robots are employed to check the bottom of bullet trains during the Spring Festival travel rush in Shanghai Hongqiao Maintenance Center.

The intelligent detection system was put into use at the center in May 2019
after more than four years of research, development, trial and evaluation.

If any problem occurs, robot "doctors" will automatically notify machinists.

They can improve the efficiency and safety of high-speed train maintenance.
