Tiangong robot Omni wins 400m sprint gold with 45.66 seconds_我的网站

A | (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)
。北京时间1月14日早些时候,美国财经媒体CNBC报道,虽然苹果的健康记录功能还没有被广泛使用,但刚刚发布的第一份关于该服务的研究表明,用户对其功能有着积极的看法。加州大学圣迭戈分校(University of California,San Diego)是最早纳入苹果健康记录的医院之一,研究人员花了数月的时间对患者进行技术调查,并于周五在美国医学协会(American Medical Association,JAMA)杂志上发表了他们的研究结果。医院允许任何使用iPhone的患者使用健康应用程序查看其实验室数据、图表、免疫信息等。在其研究中,医院向425名在2018年激活该应用程序的患者发送了匿名在线调查。96%的受访者表示他们可以轻松地连接数据,78%的人对服务满意,90%的人表示他们已经改进了与朋友和家人分享个人健康信息的过程。不到一半的人认为这三个方面都有所改善。研究人员还表示,截至2018年底,该医院有“数百名苹果健康记录用户下载了数千份临床结果”。

B | 对于一家大型医院来说,这一数字并不高,但该医院发言人克里斯托弗·朗赫斯特(Christopher Longhurst)表示,一旦医院开始向患者推广服务,这一数字可能会随着时间的推移而增加。因此,医院需要更多的数据来证明价值的增长。”我们的反应率很高,我们收到了一些积极的反应,但这些只是早期的采用者。”兰格斯特在一次采访中说。医院在使患者能够使用电子系统查看其医疗信息方面一直面临着重大挑战,因为相关技术往往设计不当,难以使用。硅谷公司以其一流的用户体验为傲,他们不仅试图简化产品,而且还试图将来自不同医院的不同医生的数据连接起来,以解决这个问题。

C | 谷歌早期的努力以失败告终,并于2011年关闭了该项目。

D | 但是现在,移动技术无处不在,通信标准也得到了提高,业界似乎对这项工作有了更大的兴趣。朗斯特的团队说,现在可能是在相关技术上取得实际进展的最佳时机,而且苹果有一个独特的优势,因为它的设备非常受欢迎。但最终,朗斯特说,苹果必须向公众证明其产品是“有用的、可持续的、可扩展的,而且确实可以改善健康。
