Unitree G1 Prototype Withdraws from World Robot Mount Tai Competition Due to Overheating

At the inaugural World Robot Mount Tai Competition in Taian, Shandong, a Unitree G1 prototype withdrew due to overheating. Experts attribute this to thermal management limits under continuous high-load climbing rather than ambient temperature, noting that stage performance does not equate to sustained work duration. The event underscores challenges in autonomous adaptation to irregular terrain, safety protocols requiring human intervention during slips or instability, and the industry shift from evaluating action variety to measuring reliable effective working hours.
