UBTech Robotics Walker C
The UBTech Walker C is a full-size service humanoid built for reception, guiding and visitor engagement in places like malls, airports and exhibitions. It stands 163 cm, weighs about 43 kg, has 20 degrees of freedom, and debuted in late 2025 at an estimated $41,200. It's available to buy on a request-a-quote basis and has already served as a guide at the China Pavilion at Expo 2025 Osaka.
What is the UBTech Robotics Walker C?
UBTech is one of the more established names in humanoids, and the Walker C is its play for the commercial service market. Where UBTech's Walker S line is aimed at factories, Walker C is the friendly front-of-house version — a robot to greet people, answer questions, and walk them around a space.
It's also one of the rare full-size humanoids you can actually buy right now, rather than just inquire about vaguely. There's a real (if approximate) price, real deployments, and published specs, which already puts it ahead of a lot of announced-but-not-shipping competition.
This review covers what Walker C does, what it costs, how capable it really is, and whether a 40-grand greeter robot makes sense for your business.
What is the UBTech Walker C?
Walker C is a full-size, electric-driven service humanoid standing 163 cm tall and weighing a relatively light 43 kg. It has 20 degrees of freedom for reasonably fluid, human-like motion — it can walk, jog up to about 6 km/h, and avoid obstacles as it moves.
Its job is guiding and reception: welcoming visitors, giving tours, and engaging people in commercial and public spaces such as malls, airports and exhibition halls. Conversation is handled by UBTech's own Embodied Interactive Large Model, which supports multilingual Q&A, scripted tour narration, and context-aware introductions to exhibits or facilities. In short, it's a talking, walking greeter rather than a heavy-lifting worker.
How much does the UBTech Walker C cost?
Walker C debuted in late 2025 with an estimated price of about $41,200. Note the word estimated — UBTech generally sells these on a request-a-quote basis, so the final figure depends on configuration, support and region. The roughly ¥299,000 yuan figure often cited maps to that same ballpark.
That's a lot for a greeter, but it's actually toward the more accessible end for a full-size, name-brand humanoid you can genuinely purchase. For a business weighing it against a human receptionist or a novelty attraction, the math depends heavily on foot traffic and how much marketing value the robot generates.
Walker C availability and release
Walker C launched in late 2025 and is available to buy now, with pricing on request through UBTech and its resellers. It's not a locked-down enterprise-only inquiry product in the way some Chinese industrial humanoids are — you can get quotes and specs relatively openly.
Deployment is already real: Walker C served as the first embodied-AI 'tour guide' at the China Pavilion during Expo 2025 in Osaka, Japan, giving guided tours at the pavilion's South Plaza. That's a solid public proof point that the robot works in a live, high-traffic setting and isn't just a showroom prop.
How autonomous is the Walker C?
Walker C handles its own navigation using U-SLAM, with dual RGB-D and structured-light 3D cameras plus a high-precision IMU for localization and obstacle avoidance. So it can move around a mapped space on its own and interact via speech and body language.
Where expectations should stay grounded is the content of the interaction. Tour guiding and reception are largely scripted, structured tasks — the robot follows planned routes and delivers prepared or context-cued information. That's exactly the right use of current tech and it works well, but it's not open-ended reasoning. Runtime is a practical limit too: roughly 2 hours of walking or 4 hours standing per charge, with about 1.5 hours to recharge the 48V battery, so a full day means either downtime or a battery plan.
Walker C vs other reception humanoids
Against greeter rivals like Hisense's newly announced Harley or various Pudu service robots, Walker C's big advantage is that it's shipping, priced, and already deployed at a world-class venue. UBTech also has a deep humanoid track record, from the Walker S industrial line to earlier Walker X.
Compared to UBTech's own factory robots, Walker C trades payload and rugged manipulation for a lighter, more sociable design tuned to public spaces. And versus a cheaper wheeled kiosk or screen-on-wheels robot, Walker C offers a genuinely bipedal, expressive presence — which is the point if the goal is drawing attention. If you just need wayfinding on a screen, it's overkill; if you want a memorable human-like host, it's well suited.
Is the UBTech Walker C worth it and who is it for?
Walker C is for businesses and venues — malls, airports, museums, exhibitions, corporate lobbies — that want an eye-catching, multilingual host and can justify a roughly $41,200 spend against foot traffic and brand impact. It is not a home or companion robot, despite 'companion' sometimes appearing in listings; its real strength is public-facing reception.
If your goal is guiding and engagement in a busy space, Walker C is one of the safer bets in this category precisely because it exists, has a price, and has a real Expo deployment behind it. Just plan around the battery runtime and remember the smarts are strong-but-scripted, not a free-roaming AI.

Should you consider the UBTech Walker C?
Walker C is a rare thing in humanoids: a full-size service robot you can actually buy, at a semi-reasonable ~$41,200, with a real Expo 2025 deployment to prove it works. For malls, airports and venues wanting a striking multilingual host it's a strong pick — just budget for the modest battery runtime and know its smarts are capable but scripted.
