UBTECH Robotics has posted a 64-second clip titled “Robots Building Robots” from the smart factory where, according to reporting on the plant, it primarily produces the Walker S series and Cruzr series. The description states that one humanoid robot rolls off the line every 10 minutes. That figure is a line design specification quoted by the company, not a measured output, and the upload carries no narration to qualify it.

Sixty-four seconds of Liuzhou assembly line

The upload runs just over a minute and has no narration, so everything said about it comes from the title, the description and the footage. The title calls the site the world’s first 10,000-scale humanoid robot smart factory and says it goes into mass production. The description says the factory “just goes live” and that UBTECH made the leap “from 1,000 to 10,000 units” in less than nine months. It describes a comprehensive intelligent manufacturing system built for over 10,000-unit production of humanoid robots. Reporting on the same plant places it in Liuzhou, in the Guangxi Zhuang Autonomous Region, at 14,000 square metres and 13.8 metres high. UBTECH says the site holds a fully automated stereoscopic warehouse for humanoid robots occupying only 65 square metres and storing 112 robots. The description does not say which of those areas the camera visits.

From 1,079 units sold to 10,000 designed

The described leap “from 1,000 to 10,000 units” sits on a dated sequence. UBTECH announced on 17 November 2025 that it had mass produced and delivered a first batch of “several hundred” Walker S2 units. On 30 December 2025 the 1,000th Walker S2 rolled out of the Liuzhou plant, and Interesting Engineering reported that more than 500 Walker S2 units had been delivered and were operational at that point. UBTECH’s FY2025 results record a sales volume of 1,079 units. The other end of the leap is capacity rather than output: Global Times describes the facility as designed for 10,000-unit capacity, and UBTECH’s own November 2025 statement set an annual capacity target of 5,000 industrial humanoid robots, which the company said would scale to 10,000 units.

No stopwatch, no cycle time on screen

A 64-second edited clip cannot show a sustained production run. No independent verification of sustained cycle time has been published, and nothing in the upload states how many robots the line has completed this year, what the rework rate is, or what playback speed the footage uses. UBTECH’s factory footage has drawn a direct challenge before: on 14 November 2025, Figure CEO Brett Adcock publicly alleged on X that an earlier UBTECH mass-delivery video contained CGI, writing “The bot in front is real – everything behind it is fake.” Humanoids Daily reported that UBTECH responded by post.

What UBTECH states about Liuzhou

• Stated: the description says “One humanoid robot rolls off the line every 10 minutes.”
• Stated: the description claims the move “from 1,000 to 10,000 units” took less than 9 months.
• Stated: reporting on the plant says it was built jointly with Siemens Digital Industries Software, using a co-developed manufacturing operations management system.
• Not stated: the video has no narration, and no playback speed is given.
• Not stated: any current-year production figure, against the FY2025 sales volume of 1,079 units.
• Not stated: any price, delivery schedule or named customer for output from this factory.

Siemens, Walker S2 and the order book

Unitree Robotics, AgiBot, Fourier Intelligence, EngineAI, Figure AI, Tesla, Agility Robotics, Apptronik and 1X Technologies are all chasing humanoid production at volume. For the 10-minute figure to mean anything, the line would have to hold that cycle across shifts, and the finished units would have to leave against real orders. Part of the order book is public: UBTECH’s November 2025 release claimed orders exceeding 800 million yuan since early 2025 and named BYD, Foxconn, Geely Auto and SF Express among its customers, while not saying which are paid production deployments and which are trials. The figure worth watching next is not design capacity. It is units delivered in the next set of audited results.
