A humanoid robot went head-to-head with a former tennis champion in what was billed as the world's first human-robot tennis singles match, showcasing its ability to move, return shots and even recover from a fall during a high-intensity rally.
The match took place on Saturday as the second World Humanoid Robot Sports Games got underway. On one side of the net was Chinese tennis star Zheng Jie; on the other was a humanoid robot developed by Galbot.
The event kicked off with an entertaining mixed doubles match, in which the robot Xingzai impressed audiences with its nimble movement. It quickly moved forward and backward as needed and worked seamlessly with its human partner, with the pair adopting a complementary front-and-back formation against their opponents.
The spotlight then turned to the singles match between Zheng and the humanoid robot.
The robot held its own in rallies, trading both forehand and backhand shots with Zheng. When Zheng raised the difficulty by sending over a high, looping ball, the robot was pushed from side to side and eventually lost its balance, landing flat on its back. But it quickly recovered, adjusting its posture and getting back on its feet within seconds.
The robot also showed a surprising ability to read Zheng's slices and spin. When Zheng began moving it deliberately from side to side and from front to back, the robot responded with an impressive lunge that drew cheers from the crowd.
Throughout the match, the robot performed actions including bending its knees, tossing the ball and rotating its body entirely on its own.
The robot's serves surpassed 100 kilometers per hour, leaving it only fractions of a second to react, yet it rarely faltered under the pressure.
AlphaGo defeated South Korean Go champion Lee Sedol 10 years ago, demonstrating the power of AI in the digital realm. A decade later, a Chinese humanoid robot is stepping onto the court alongside an elite tennis player.
If AlphaGo showed that AI could master the digital world, the tennis match offered a glimpse of how AI-powered robots are beginning to withstand the demands of the physical world, experts said.
For the first time, AI was no longer confined to code. The robot ran, swung its racket, competed in real-time — and even picked itself up after falling, before carrying on with the match.
。1月14日，国家新办召开了登月工程“嫦娥四号”任务新闻发布会。国家航天局副局长、探月项目副主任吴燕华在发射会议上表示，中国探月项目和深空探测项目的第四阶段已经全面启动，标志着“嫦娥四号”任务的成功。

二 | 今年年底前后将实施“嫦娥五号”月球采样与返回任务，2020年左右将实施中国第一次火星探测任务。早些时候，联合国外层空间司司长迪皮蓬说，嫦娥四号飞行任务标志着空间探索史上一个不可思议的里程碑，这不仅是中国取得的巨大成功，也是国际空间工业向前迈出的重要一步。吴艳华表示，感谢国内外同行、朋友和媒体对中国航天事业的关注。到2020年，中国探月工程将实现“前后”三步走的目标。除了月球探测项目，她还说中国将在2020年左右执行火星探测任务。
