Unitree Taishan Robot Race: Robot dog wins championship, G1 humanoid robot overheats and withdraws
At the Taishan Robot Race, Unitree's quadruped robot won the robot dog sprint championship with a time of 43 minutes and 41 seconds, but the G1 humanoid robot overheated after climbing all 3,100 stone steps and was carried off the course on a stretcher. The humanoid robot's compact joint housings accumulated heat during 45 minutes of continuous uphill walking, triggering the overheat protection, after which it squatted down and shut off; by contrast, performing a controlled backflip on a mat requires only 3 seconds of burst power. This shows that humanoid robots are not yet ready for commercialization.

Unitree experienced mixed outcomes at the Mount Tai Robot Race in China, which required robots to climb 3,100 stone steps.
On a positive note, Unitree's quadruped robot won the robotic dog sprint category with a time of 43 minutes and 41 seconds. However, its G1 humanoid robot overheated during the climb and had to be removed from the course on a stretcher. Unlike quadrupeds, a bipedal humanoid like the G1 builds up massive heat inside compact joint housings until thermal protection forces a squat-and-shutdown.
Controlled backflips on a gym mat require only 3 seconds of burst power. However, sustained 45-minute uphill locomotion in the wild presents a completely different challenge, demonstrating that these humanoids are not yet commercially ready.
