Laden with eggs, robots race up sacred Chinese mountain

Dozens of robots embarked on a challenging trek up Mount Tai, one of China’s most iconic peaks, on Monday, carrying eggs and watermelons in a race aimed at testing the endurance of real-world machines, state media reported. Mount Tai, situated in eastern Shandong province, holds great significance for Chinese emperors and is steeped in Chinese mythology.

However, the mountain's rugged terrain posed a formidable obstacle for some competitors. A humanoid robot adorned with a bandana was seen collapsing on the cobbled path before engineers arrived to render assistance, while another robot accidentally tumbled down a staircase and came to a stop beside a rubbish bin.

The UNESCO World Heritage site provided a stage for showcasing cutting-edge technology as part of the World Mountain Robot Challenge, a new event featured by state broadcaster CCTV. Over a 3.9-kilometre course with an elevation gain of over 600 metres, robots from around 90 teams competed in either a timed race or a task requiring the transportation of delicate goods like eggs and watermelons to the summit.

The canine robot created by Beijing Lingyi Technology, a subsidiary of the industry giant Unitree, emerged victorious in the four-legged speed category, completing the course in 43 minutes and 41 seconds. Most tourists typically take at least two hours to ascend the mountain, according to CCTV.

The fastest humanoid robot, belonging to the Beijing-based team Zhishen Lingyue, raced a shorter course in an impressive 27 minutes and 26 seconds. Organizers, operated by the state-run China Media Group, described Mount Tai's rocky terrain as a "natural extreme testing ground" that could assist in preparing robots for real-world applications. The race included cash prizes for winners in various categories, including the fastest robots and the most proficient load-carrying four-legged machines.
