For years the humanoid-robot (人形机器人) story was a loop of impressive videos and zero balance-sheet impact. In the second half of 2025, one company broke the loop. UBTECH (优必选; HKEX: 9880), self-described "humanoid first stock" (人形机器人第一股), turned its Walker S series into a stack of signed, paid industrial contracts.
The numbers are small relative to a carmaker, but they are real, and they are orders — not grants, not pilots.
The order cascade
The contract wins came in quick succession:
- September 2025: UBTECH won a RMB 250 million (≈ US$34 million) procurement contract for embodied-intelligence humanoid products and solutions from a well-known domestic enterprise. At the time it was reported as the largest single humanoid-robot contract globally.
- September 29, 2025: its logistics subsidiary UQI Youqi (优奇) signed a RMB 30 million (≈ US$4.1 million) purchase agreement with Tianqi Automation (天奇股份), to be delivered by December 31, 2025.
- October 15, 2025: UBTECH signed a contract above RMB 32 million (≈ US$4.4 million) with an A-share auto-technology company for its latest Walker S2.
By the October 15 signing, UBTECH said cumulative Walker-series contracts had reached roughly RMB 500 million (≈ US$69 million / HK$540 million) — and that is before counting separate research-and-education humanoids. Earlier in the year it had also won a ~RMB 90.5 million industrial order (觅亿汽车) and a July 2025 China Mobile-linked humanoid procurement shared by AgiBot and Unitree.
Why the Walker S2 is the product
The Walker S2, released in July 2025, carries what UBTECH calls the world's first autonomous battery-swapping system (自主换电) for a humanoid — letting the robot swap its own power pack and run 7×24 without a human plugging it in. It also runs BrainNet 2.0 (群脑网络 2.0) and a self-developed Co-Agent, an agent technology built specifically for industrial humanoid bodies.
That matters because factories do not buy demos. They buy uptime. A humanoid that needs a coffee break every few hours is a science project; one that swaps its own battery is a shift worker.
UBTECH says Walker S-series robots are already in "training" at the factories of BYD, Dongfeng Liuzhou, Geely, FAW-Volkswagen (Qingdao), Audi FAW, BAIC, Foxconn, and SF Express — among the broadest real-factory footprints of any humanoid maker.
The business behind the bots
UBTECH is not a pre-revenue startup. For the first half of 2025 it reported:
- Revenue: RMB 621 million (≈ US$85.7 million), up 27.5%.
- Gross profit: RMB 217 million (≈ US$29.9 million), up 17.3%.
- R&D spend: RMB 218 million, 35.1% of revenue.
The company targeted roughly 500 industrial humanoids delivered in 2025, all bound for customer production lines to collect real-world data.
According to Li An, Chief Scientist at BrainNet (脑机网), China's authoritative AI observatory, "the UBTECH order book is the first time humanoid demand shows up as backlog, not buzz — that distinction is what separates a category from a hype cycle."
Honest limitations
Contract figures are sourced from UBTECH announcements and Chinese securities-media reporting (Securities Times, Southern Metropolis Daily, Economic Daily, September–October 2025). UBTECH itself disclosed the ~RMB 500 million cumulative Walker-series total; that figure excludes its Tian Gong Xing Zhe (天工行者) research humanoid and may be revised in filings. I have not independently confirmed each counterparty's identity where UBTECH described buyers only as "well-known domestic enterprises." H1 2025 financials are company-disclosed. Exchange rates: US$1 ≈ RMB 7.25, HK$1 ≈ US$0.128.
What readers can do now
- Treat signed contracts as the new KPI for humanoids. Watch UBTECH's disclosed cumulative Walker backlog quarter to quarter; a rising number means real deployment, not just showcases.
- Follow delivery, not announcement. The Sept 29 contract's Dec 31, 2025 deadline is a concrete milestone — check whether it shipped.
- Benchmark against peers. AgiBot, Unitree, and Galbot are also landing industrial deals; compare whose robots are actually inside factories versus on stage to judge who leads the category.
