一名持刀闯入者被制服。一辆汽车被举起以解救被困受害者。一名行人被从迎面驶来的车辆路径中拉离。

上述场景并非出自好莱坞大片，而是中国科技公司宇树科技为其新款“守护者”机器人制作的一段宣传片。
The scenes described are not from a Hollywood blockbuster, but a promotional clip for a new “guardian” robot created by the Chinese technology firm Unitree Robotics.
这段于周三发布的H2-X机型视频，凸显了这家总部位于杭州的公司战略上的更广泛转变，即专注于为其运动型机器人寻找实际的现实应用场景。
The footage for the H2-X model, released on Wednesday, underscores a wider shift in strategy by the Hangzhou-based firm, as it focuses on finding practical, real-world uses for its athletic robots.
宇树科技凭借一系列病毒式传播的特技表演一举成名——其机器人表演武术套路、舞蹈和空翻——帮助公司筹集了巨额资金。但中国机器人行业目前面临着交付商业回报的日益增长的压力。
Unitree shot to fame with a series of viral stunts – with its robots performing martial arts routines, dances and somersaults – helping the company raise massive amounts of capital. But China’s robotics industry is now coming under growing pressure to deliver commercial returns.
宇树科技近期发出转向实用能力的信号。上个月，该公司宣布其UnifoLM-X2-1.0人工智能模型使人形机器人能够通过出拳、格挡和闪避进行自主对练。
Unitree recently signalled a pivot towards practical capabilities. Last month, the company announced that its UnifoLM-X2-1.0 artificial intelligence model allowed humanoid robots to spar autonomously by punching, blocking and dodging.
H2-X——被命名为“功夫传奇：守护者”——是在宇树科技H2机型基础上打造的，后者是一款全尺寸人形机器人，身高1.8米，重约70公斤。
The H2-X – dubbed “Kung Fu Legend: Guardian” – builds on Unitree’s H2 model, a full-sized humanoid standing 1.8 metres tall and weighing about 70kg.
根据其产品介绍，早期机型拥有31个自由度，最大腿部关节扭矩为360牛顿米——尽管宇树科技未确认H2-X是否将保留这些规格。
According to its product description, the earlier model had 31 degrees of freedom and a maximum leg-joint torque of 360 newton metres – though Unitree did not confirm whether the H2-X would retain these specifications.
公司表示，新款机器人站立状态下可运行约八小时，但未透露该机器人何时上市、价格多少，也未提供详细技术规格。
The company said the newer model could operate for about eight hours while standing, but did not disclose when the robot would go on sale, how much it would cost, or provide detailed technical specifications.
宇树科技也没有说明宣传视频中展示的动作是自主完成的，还是经过某种编排。也没有说明H2-X能否在非预设环境中独立识别威胁并安全响应。
Unitree also did not clarify whether the actions shown in the promotional video were performed autonomously or were choreographed in some way. Nor did it say whether the H2-X could independently identify threats and respond safely in unscripted environments.
Unitree在视频结尾发出了警告，提醒用户不要对机器人进行危险性的改造或未经授权的使用，并建议用户与机器人保持至少两到三米的距离以确保安全。
Unitree concluded the video with a warning against dangerous modifications and unauthorised uses, advising customers to maintain a safety buffer of at least two to three metres from the unit.
周三，当记者联系该公司寻求评论时，公司代表拒绝提供更多细节，仅表示“所有相关信息都将在官方发布的公告视频中公布”。
When contacted for comment on Wednesday, a company representative declined to provide additional details, stating that “everything is subject to the official announcement video”.
这款新机器人的亮相正值Unitree及其竞争对手面临投资者日益严格的审查之际——投资者要求公司明确可持续收入增长的路径、具备技术优势，并提供可行的应用场景。
The new robot’s unveiling comes as Unitree and its peers face heightened scrutiny from investors demanding clear paths to sustainable revenue growth, technological moats and viable deployment scenarios.
周三，Unitree的股价下跌了2.1%，收于515元，结束了此前连续三天的上涨趋势（期间股价累计上涨了近30%）。目前该股票的股价较其8月份在上海星板上市时的初始价格845元已下跌了约39%。
Unitree’s shares closed down 2.1 per cent at 515 yuan on Wednesday, snapping a three-day rally that had seen the stock gain nearly 30 per cent. The stock is down about 39 per cent from its debut price of 845 yuan, achieved during its listing on Shanghai’s Star market in August.
在周二提交的一份监管文件中，该公司表示并未掌握任何可能引发近期股价异常波动的未公开信息。
In a regulatory filing on Tuesday, the company said it was unaware of any undisclosed information driving a recent unusual stock price movement.
