UBTech Walker C1

What the Walker C1 is

The UBTech Walker C1 is a full-size bipedal humanoid built for service work in public spaces. It sits in the same Walker product line as the Walker S2 but does a different job — the S2 goes into factories, the C1 works front-of-house.

On its own product page UBTech describes it as “the world’s first full-size humanoid service robot designed for urban symbiosis”, driven by a multimodal intelligence engine built on AI models and embodied-AI technology. That is the company’s own marketing language, not a test result.

Verified specifications

Every line below comes from UBTech’s own Walker C1 product page, cross-checked against both the English and Chinese versions, which agree.

Specs with no public source: battery hours / runtime per charge, charging time, battery capacity, per-arm payload, DoF in the hands, IP rating, noise level, stair and uneven-surface capability, price, and the official launch date. UBTech does not publish these, so we leave them out rather than estimate. Note that UBTech’s “Product Specifications” section is a sensor callout diagram, not a numeric spec table.

Why the numbers here differ from other sites

The most widely-circulated figures for the Walker C1 are 165 cm, 50 kg and 26 DoF (10 in the hands). That set comes from third-party spec aggregators such as humanoid.guide and has been repeated onward — but it does not match what UBTech publishes, which is 164 cm / 55 kg / 53 DoF.

We do not know where 165/50/26 originated. It may describe a prototype shown at the unveiling, or it may simply be a compiler’s error. What we can verify is that the manufacturer’s own page, in both English and Chinese, says 164/55/53 — so that is what this page uses.

The launch date has the same problem: reports give different days (9, 20 and 23 May 2026 all appear), and UBTech’s own newsroom carries no dated release. We therefore state only the year, 2026.

What UBTech says it is designed for

The product page groups the applications into four (these are the company’s own words, not confirmed installations):

• Commercial services — multilingual reception, AI tour guide, shopping assistance
• Cultural entertainment — themed event performances, visitor interaction
• Urban safety — patrol inspection, traffic assistance
• Education and R&D — smart teaching assistance, research and development platform

UBTech also states that standard interfaces and an SDK are available for customisation, and that the modular design allows single-person deployment.

What to know before you evaluate one

No price, in any currency. Unlike the UWORLD U1, for which UBTech announced yuan pricing at launch, the Walker C1 has no public figure at all — purchase or rental. You cannot build an ROI model on it yet.

No company-announced deployment. The only claim on the product page is the role as first official humanoid representative of the 4th China International Supply Chain Expo — an event appearance, not a hotel or airport posting.

The hands are an option. If your use case involves picking anything up, confirm whether the quoted configuration includes the dexterous hands.

No battery figure. For a lobby or event robot expected to stand a full day, runtime per charge is the number that decides whether it works. UBTech has not published it.

Who should skip this one

• Anyone who needs a payback calculation before buying — with no price, no battery hours and no payload, there is no ROI model to build.
• Anyone who needs delivery this year with local Thai support — we found no Thai distributor announcing itself.
• Anyone whose core job is carrying or handling objects — the hands are optional and no payload figure is published. If you need a delivery robot with complete specs and real availability, look at the service robot category instead.
• Sites with uneven floors or stairs — UBTech publishes nothing about the C1 on non-flat surfaces.
