Robotic Quadrupeds and Humanoids Race Up Mountain Staircase

Engineers in China recently gathered on the steep trails of Mount Tai to test their machines in a challenging outdoor obstacle course. As reported by CGTN Europe, nearly ninety teams featuring four-legged quadrupeds, two-legged humanoids, and powered exoskeleton suits participated in the event. The competition forced the machines to climb over three thousand uneven stone stairs across a distance of nearly four kilometers.

While laboratory tests show how well a robot moves on smooth factory floors, real-world terrain reveals how balance algorithms handle unpredictable surfaces. Watching four-legged machines power up mountain trails in under three quarters of an hour demonstrates that mechanical legs are rapidly approaching human speed on rough ground. If these devices can handle slippery, irregular stone steps without falling, they could soon assist search and rescue teams in natural disaster zones or transport supplies to remote areas where wheeled vehicles cannot travel.

Despite the impressive performance of four-legged units, two-legged humanoid designs still struggle to match the speed and balance of their quadruped counterparts on extreme inclines. Battery life also remains a major hurdle during extended physical exertion. It is still unclear whether these machines were operating entirely autonomously or relying on human remote operators for step selection. Furthermore, will commercial adopters accept the high maintenance costs of joint actuators that endure such brutal, repetitive physical impact in outdoor environments?
