新素材 社会热点 The world’s first human-like robot half-marathon（半程马拉松）was held in Beijing on 19 April. Amazingly, 20 robots joined about 12,000 human runners in the race.
The robots were different, from the 18-centimetre-tall “Tiangong Ultra” to the 75-centimetre-tall “Little Giant”. They had human-like looks and ran on two legs. Each robot started at a slightly different time so that they would not bump into each other. To give each robot the best chance, each travelled with support workers. Just as human runners needed to get energy from water, the robots were allowed to get new batteries during the race. Companies were also allowed to replace(替换）their robots when they could no longer run.
The first robot to cross the finishing line was Tiangong Ultra. It finished the race in 2 hours, 40 minutes and 42 seconds, while the winner of the men’s race finished in 1 hour and 2 minutes. To the robots, the most important thing was not to win, but to finish. At last, six of the robots crossed the finishing line.
The race was a success, even for the robots who didn’t finish. Their efforts will help their developers improve future human-like robots. The race also marked the first time in human history—human-like robots have tried a half-marathon.
However, the marathon also displayed some weaknesses of the robots. They needed people to change their batteries, prevent falls, and even control them. These challenges show hidden problems in the field: behaving like humans requires further work in materials science, storing power and AI learning abilities.
In the future, as AI gets smarter, the gap(差距）between humans and machines will narrow. For China, developing these human-like robots isn’t just about making them run faster—it’s about which country can make full use of science and technology to take the lead in the world. And in that marathon, every fall and hard-won step matter.

Human-like robots run a half-marathon in China
Introduction
Twenty robots ran 56 with thousands of human runners in a half-marathon in Beijing on 19 April.
About the robotic runners
• The robots were not in the 57 size, but they all looked like humans with two legs.
• Each robot started at a different time to reduce the 58 of bumping into each other.
• Batteries could be changed and robots could even be replaced if it was 59.
Results
• Tiangong Ultra came first, although it was far 60 the human winner.
• Six of the robots 61 to finish the race.
Meanings
• It will help further develop human-like robots in the future.
• China made 62 because the event marked the first time for human-like robots to try a half-marathon.
