Twenty robots joined human runners in the 21-kilometre race. However, only six crossed the finish line. The winner, Tiangong Ultra—a 1.8-metre-tall robot weighing 55 kilograms—finished in 2 hours, 40 minutes, and 42 seconds, moving at a pace similar to that of a fast walker. The race wasn’t just fun—it tested key robot technologies. Organizers said the race helped robots improve balance, battery life, and movement control. Robots needed strong joints, smart software, and the ability to handle slopes and turns. “This event helps us upgrade robots for future jobs in factories or homes,” said Xiong Youjun, a robotics expert. China aims to lead the world in humanoid robots. In 2023, the government made them a top priority, planning mass production by 2027. While US companies like Tesla build expensive robots, Chinese companies focus on affordability. For example, Unitree’s G1 robot costs $16,000 which is cheaper than Tesla’s Optimus robot. Unitree even announced a robot boxing match to mix technology with entertainment! The impact of these robots is already being felt. Chinese factories already use robots. Car company Dongfeng uses 20 humanoid robots to build cars and manage supplies. Experts predict China will make over 10,000 humanoid robots this year, more than half the world’s total. As costs drop, robots may soon help in schools, hospitals, and homes. The half-marathon marked a major milestone in China’s robotics industry. The organizer called it a “starting gun” for a robot revolution. “It’s about how humans and robots can work together,” he said. “Robots are already helping build cars and move goods in factories,” said engineer Xie Shaofeng. With lower costs and better technology, China’s robot industry is growing fast. Reports say it could boost the economy. Soon, you might see robots jogging in marathons—or working beside you! 10.How does the writer lead to the topic? A.By listing numbers from the race.
