Tai'anA robot dog won the Mount Tai climb in 43 minutes, 41 seconds.
Organisers billed the stair course as a real-world endurance test for around 90 teams.
The 3.9-kilometre route rises more than 600 metres, and some robots carried eggs and watermelons to the summit.
One humanoid collapsed on the cobbles and another tumbled down a flight of stairs, state broadcaster footage showed.
No source reports how many robots finished or how many eggs arrived intact.
