梅花三弄

IT之家 8 月 22 日消息，由北京市人民政府、中央广播电视总台等单位联合主办的第二届世界人形机器人运动会今天开幕。         An aerial drone photo taken on March 19, 2025 shows the construction site of the Chinese-built Talanta Sports City in Nairobi, Kenya. (Xinhua/Han Xu)In Nairobi, a 60,000-seat football stadium is entering the final stage of construction. Built in just two years, the Talanta Stadium will serve as the main venue of the 2027 Africa Cup of Nations, co-hosted by Kenya, Uganda and Tanzania.
"The schedule was extremely tight -- just two years, while comparable projects elsewhere usually take more than three," Du Xiao, project manager of the stadium for China Road and Bridge Corporation (CRBC), told Xinhua in a recent interview. "There is a very real sense of pride."
According to Du, the stadium has no running track, bringing spectators close to the pitch. Its seats take on the green, red and black of Kenya's national flag, while the facade features the traditional shield and spear of the Maasai people.
Upon completion, the stadium is set to be renamed the Raila Odinga International Stadium, in honor of Kenya's late former Prime Minister Raila Odinga.
The roof adopts a cable-supported grid system erected with a "cable-first, steel-after" method, which Du said is the first of its kind independently designed and built by China. Without temporary steel supports, 48 radial cables are tensioned to lift six ring cables before steel trusses are laid on top, saving at least three months of construction time, with displacement controlled to the millimeter. In 2025 alone, some 1,300 containers of materials and equipment were shipped from China to the site.
For CRBC, the stadium is only the latest chapter of a much longer story. The company built its first road in Kenya in 1984, and over 42 years, its footprint has extended from roads to bridges, ports, railways and buildings.
Du Shan, the executive general manager of CRBC Kenya office, recalled that before 2008, Nairobi was cut apart by three rivers and a cross-district trip could take more than three hours. After CRBC completed the ring roads, the journey now takes about 50 minutes. The company is also expanding the A8, a national trunk road, from two lanes to four and six, she said.
On the Mombasa-Nairobi Standard Gauge Railway, wildlife corridors were built with a clearance of more than six meters, "so that giraffes can pass with their heads held high," Du Shan said.

(Xinhua/Han Xu)Du Xiao arrived in Kenya in August 2011 and has worked on the ring roads, the Mombasa-Nairobi railway, the Nairobi-Malaba railway and the Nairobi Expressway before taking on the stadium project.
"Working overseas, we should not arrive thinking about changing the place. We should first adapt to and learn from the local community," he said. "What many projects truly open up is not just roads and railways, but trust between people."
The stadium sits near Kibera, Kenya's largest informal settlement. Du Xiao remembers a local young man named Sammy, who had no skills when he applied for a job but volunteered for the project's equipment training and became a pump truck operator. "I asked him why he worked so hard. He said, 'I never thought I would have the chance to touch these machines. Now I feel I can support my whole family.'"
According to Du Shan, the project recruited nearly 500 young workers from the neighborhood during construction, many of whom have qualified as assistant engineers, while about 280 local youths were mentored into technical backbones during the construction of the Mombasa-Nairobi railway.
More than 350 CRBC employees have worked overseas for over a decade, and each year the company awards them a gold medal for long-term dedication, she said. "The medal is not only an honor, but also a kind of warmth. Because 42 years -- it has truly not been easy."
When his child was born, Du Xiao was at a critical stage of the Nairobi Expressway project and could not make it home. "People in overseas engineering live in two worlds -- the project site on one side, the family on the other. All you can do is try to do a little better on each side," he said.
"Maybe I will one day leave this country. But this stadium will remain," he said. "I came here to build projects. Then I found that this country has shaped who I am today." 
。本次比赛将持续到 26 日，共设置 51 个项目、1300 多场比赛。今年竞技赛新增跳远、举重、拔河、乒乓球等高强度对抗项目。本届运动会正赛将于 8 月 22 日至 26 日在国家速滑馆“冰丝带”举行，将举行 51 个项目共 1301 场比赛，吸引 666 支队伍携 2056 台机器人参赛，竞赛项目、参赛队伍全面提质扩容。从报名情况来看，各路高手将云集赛场。本届赛事吸引了来自六大洲、16 个国家的 666 支队伍，共有 2056 台机器人同台竞技，队伍数量较首届增长 138%，机器人数量翻了两番。国际方面，美国、德国、日本等机器人传统强国赛队积极参与，巴西还集结了五支机器人足球世界杯队伍，组建起一支国家联队参赛。国内方面，157 家企业、200 所院校和科研机构的 641 支队伍、1975 台机器人齐聚赛场。国内第一梯队企业悉数到场，27 所 985 高校踊跃参赛，产学研用各方力量汇聚一堂。

B | IT之家从官方介绍获悉，今年赛项从首届的 26 项增加至 51 项，其中竞技赛 30 项、场景赛 21 项；比赛场次从 487 场增至 1301 场。在竞技赛中，今年新增的跳远、举重、拔河、乒乓球等高强度对抗项目，都是对机器人大脑、小脑、本体结构以及核心零部件的极限考验。赛场上每多跳远 1 厘米、每多举起 1 公斤，都是工程师们对关节电机、减速器不断优化设计、精密加工、测试验证的结果。此外，田径场比拼将更加激烈，机器人足球比赛将实现带球跑动、大力抽射等技能提升，更有百支队伍上演“舞林争霸”。本届场景赛则将赛项延伸到真实环境，覆盖工业、酒店、家庭、物流等领域，并专门设置了灵巧手赛项。其中，灵巧手设有夹豆子、拧螺丝等 8 个“微操”赛项，上演指尖对决。相比去年场景赛机器人仅“一个人战斗”，本届升级为机器人两两同台比拼，进一步增加赛事的精彩程度和观赏性。
