Robots aid maintenance work on UHV power line

HEFEI — A robotic dog trots back and forth between the transmission towers at the Guquan converter station in the mountains of eastern China, conducting a thorough inspection of the grid facilities.

"The robotic dog is equipped with two infrared cameras capable of identifying equipment defects such as loose mechanical connections and gas leaks," said staff member Sun Chaopeng.

The four-legged robot sets out at a fixed time every day and automatically returns to recharge its battery. It is just one example of the widespread use of automation technology in ensuring power supply during the winter peak in China.
