A half-marathon was held in Beijing, China. About 12,000 runners took part. On a separate track, beside the human runners, 21 humanoid robots tackled the same challenge. It was the first race of its kind. Despite the challenges, six robots finished the race.
A half-marathon is 13.1 miles (21 kilometers) long. The distance was meant to challenge the robots, and allow their developers to see how the robots managed under real-life conditions.
Each robot started at a slightly different time—a good idea, since some of the robots fell down right at the start. To give each robot the best chance, each traveled with support workers and a van holding supply parts and even replacement robots. (There was a ten-minute time penalty for replacing a robot.)
Support workers carried devices to control their robots. Some workers followed their robots; others led them. Some robots were kept on a leash. Workers helping faster robots had to jog the whole time. Those with slower robots just walked.
The early part of the race was the easiest because the course was flat. Later, things became more difficult. The course had 14 turns, and there were small hills to run up or down. In some places, railroad tracks crossed the road, and the robots had to handle the uneven surface.
Just like human runners, low energy was a problem for the robots, too. Tiangong Ultra fell once because of a low battery. The same thing happened to other robots, too.
The biggest challenge was probably overheating. It was cool in the morning, but as the day heated up, workers had to keep spraying the robots to keep them cool. At one point, Little Giant had smoke coming out of its head.
The first robot to cross the finish line was Tiangong Ultra. It finished the race in 2 hours, 40 minutes, and 42 seconds. That was far behind most human runners. But the goal of the race wasn't to win. It was to finish. And six of the robots met that goal.
The race was a success, even for the robots who didn't finish. Their efforts produced a lot of information that will help their developers improve future humanoid robots.
