Quick Answer
Walker C1 is UBTECH’s commercial service humanoid — the visored white-and-black walker the company dressed for reception, tour guiding, shopping-floor help, patrol, and the occasional waltz. It is not Walker S. It is not U1. Independent named C1 at the World Robot Conference, 19–23 August 2026, at Beiren Etrong, as the commercial launch for public-facing venue work. That is a positioning fact. It is not a spec sheet.
UBTECH’s own English product page calls C1 the first full-size humanoid service robot “designed for urban symbiosis,” lists NVIDIA Jetson Thor at 2070 TFLOPS (FP4) on a marketing slide, and talks about Thinker + Control Center + ROSA 2.0, VLN/VLA, and 3D navigation. Those are company slides. I have not seen an official C1 height, mass, payload, runtime, or DOF table that I trust enough to put in a buying row. humanoid.guide prints 165 cm / 50 kg / 26 DOF / $79,000 and marks the card unverified. I am not copying it.
Our Verdict
| Field | Rating | Reason |
|---|---|---|
| Overall Review Score | 6.1 / 10 | A real commercial SKU with an official page and a dance tape. No public spec card. |
| Commercial readiness | 6.0 / 10 | UBTECH is selling service deployments, not a hobby kit. Terms are quote-only. |
| Consumer readiness | 1.5 / 10 | This is a venue robot. U1 is the consumer face. |
| Industrial usefulness | 3.5 / 10 | Wrong tool. Cruzr Y1/S2 and Walker S are the factory names. |
| Autonomy confidence | Medium | Choreography and greeter demos. A shift in a crowded lobby is unproven in public. |
| Source confidence | Medium-low on numbers | Official page is real. Numbers are mostly missing. |
| Biggest concern | Buying a dancer and expecting a receptionist with a published duty cycle. | |
What it is
C1 is the Walker that UBTECH wants standing next to people. The official page’s application list is blunt: multilingual reception, AI tour guide, shopping assistance, events, visitor interaction, patrol, traffic assistance, teaching, research. In May 2026 UBTECH posted the Chain Expo waltz and ballet tape — “Walker C1: When humanoid robot meets elegance” — which is where the featured photo comes from. A high leg in a dance studio is evidence of balance and range. It is not evidence that C1 can work a Sunday crowd at a museum without a handler.
The same week as WRC, UBTECH’s industrial cousins were the story on the factory side. C1’s job at Beiren Etrong was the commercial one: look like a person-shaped staff member and talk. Independent treated it that way. I am doing the same.
Who makes it
UBTECH Robotics. C1 sits in the Walker family next to Walker S (industrial, already reviewed here) and Walker X (the smaller/earlier listing). If a page uses a Walker S factory still as C1, it is wrong. S has the industrial brief. C1 has the lobby brief. The chest still says WALKER. The clothes and the job changed.
What type of robot it is
Full-size bipedal commercial service humanoid. Not wheeled (that is Cruzr). Not the painted-face U1.

What it can actually do
Walk, balance on one leg, dance next to humans, and — on paper — greet and navigate. The official page also promises omnidirectional perception, a motion library, SDK/customization, and single-person deployment. I have not seen a public C1 deployment log with hours, falls, or a named hotel that will take a call about it.
Flaws
No spec card is the first flaw. You cannot size a freight elevator, a stage lift, or a liability policy without mass. The second is category confusion: UBTECH now has S, S2, X, C1, U1, Cruzr Y1, Cruzr S2. Sales decks mash them. The third is the dance. A waltz is a controlled floor with rehearsed partners. A train-station concourse is not.
Real-world usefulness
Useful as a branded greeter or show unit if UBTECH is in the room for integration. Not useful as a drop-in replacement for a person at a desk. If you need tote handling, look at Cruzr Y1. If you need a consumer face, look at U1. If you need the industrial biped we already have numbers on, stay on Walker S.
Price and availability
No public MSRP on the official page. WRC was a commercial launch, not a price list. Ask UBTECH for the live quote and the support hours that come with it.
Who should consider it / who should avoid it
Consider C1 if you are a venue, show, or municipal project already talking to UBTECH and you want the service Walker, not the factory one. Avoid it if you need published height, payload, or a robot you can buy from a storefront this week.

No. S is the industrial line. C1 is the commercial service launch.
Is the photo on this page Walker S?
No. It is from UBTECH’s official C1 product page, the ballet demonstration.
How tall is C1?
UBTECH has not published a C1 height we will repeat. Ignore unverified 165 cm cards.
