As marathoners navigated the hills of beautiful Sangju in South Korea, they noticed an odd participant at their side. A dog-like robot, named RAIBO2, trotted across winding terrain and slippery roads, finishing the race in four hours, 19 minutes, and 52 seconds—a smidge faster than the human average.

But endurance rather than speed was the robot’s main triumph. At the finish line, it had only used 66 percent of its battery power, pushing the limits of mechanical stamina.
