More than 2,000 humanoid robots competed in Beijing across athletics, soccer, boxing and practical scenarios such as hotel service and emergency response. The final 100-meter robot-Games record fell to 8.64 seconds, a dramatic improvement over the inaugural competition.

The unforgettable footage came after the finish line. Several runners plowed into padded barriers; one training clip shows a machine folding backward at the waist as sparks and smoke burst from its body. Other race footage shows robots falling, breaking apart or briefly catching fire.

That contrast is the actual story. Whole-body control is improving quickly in narrowly defined events, but speed is not the same as robust autonomy. A machine that can sprint faster than a person and cannot reliably stop is both impressive engineering and an unusually efficient metaphor.
