一 | (ECNS) -- A humanoid robot named Tiangong robot Omni clocked 45.66 seconds to win the gold medal at the 400-meter contest during the 2nd World Humanoid Robot Games in Beijing on Sunday. The robot's performance was notable not only for its speed but also for its unusual running style. Leaning sharply forward, it swung both arms close to its face, creating a comical pose that looked as if it were covering its face while sprinting. The quirky gait quickly went viral online, with Chinese netizens jokingly dubbing it a "socially anxious sprint". The contrast between the robot's high-speed performance and its almost bashful posture has made it an unexpected internet sensation. The movement was not manually programmed by engineers to imitate humans. Instead, the distinctive gait emerged autonomously through reinforcement learning in a simulation environment. During training, the robot learned that twisting its waist and driving its movement through the hips required less effort than rapidly swinging its arms. The strategy also helped reduce heat buildup in the shoulder joints. At the same time, leaning forward shifted its center of gravity in a way that improved balance and helped increase running speed. With a time of 45.66 seconds, Omni's performance is already approaching the level of elite male human athletes in China. (By Gong Weiwei)

三 | 樊振东的暂时缺位，也意味着国乒男队正式步入新老交替的关键阶段，队伍无法再依赖过往的核心阵容，必须打破固有的格局，直面新生代接班的现实课题。世乒赛作为乒坛顶级赛事，其参赛名额是实力的直接认证，更是检验选手抗压能力、竞技水准的核心舞台，唯有经得起大赛考验的选手，才能扛起国乒延续辉煌的重任。温瑞博作为国乒后备力量，此前一直缺少顶级大赛的历练，此次迎来难得的参赛契机，没有任何退路可言。竞技体育向来靠实力说话，从无温情脉脉的施舍，更不存在侥幸的捡漏。这既是他打破新人蛰伏僵局、证明自身价值的绝佳机会，也是对他心理素质、赛场应变能力最残酷的试炼，每一场比拼都关乎个人职业生涯的走向。樊振东的暂别是一段时代的暂停，更是国乒男队新生阶段的开端。温瑞博能否牢牢抓住这次机会，顶住压力打出自身风采，不仅决定着个人能否在国乒站稳脚跟，更直接关系到国乒男队新老交替能否平稳推进。唯有全力以赴、放手一搏，才能不负这份信任，为国乒男队梯队建设筑牢根基，续写国乒的荣耀篇章。
