UBTECH Walker C Commercial Reception Humanoid Robot

A humanoid robot in a lobby is never ignored. Heads turn, phones come out and children wave. The harder question for any operator is what happens after that first glance: whether the machine can greet the person in front of it, understand what they need and lead them somewhere useful. The UBTECH Walker C Commercial Reception Humanoid Robot is built for that second moment. It is a full size, electric-driven embodied intelligent humanoid that walks on two legs at human height, converses with visitors in several languages and positions its own tour routes, so that the attention it draws becomes a service rather than a spectacle.

Robots Europa, based in Dublin, supplies the Walker C to organisations across the European Union and the DACH region. We prepare each quotation around the site where the robot will work, arrange delivery and customs clearance, and remain your point of contact for support once the Walker C has entered service.

Background

UBTECH and its humanoid line

UBTECH is a robotics manufacturer whose range runs from educational and consumer robots to wheeled commercial service machines and full-size humanoids. The Walker name belongs to its bipedal humanoid work, and the Walker C is the member of that line aimed squarely at commercial reception and guided tours. Its most visible engagement to date is an international one: the Walker C is the first embodied AI tour guide of the China Pavilion at Expo 2025 Osaka, Kansai, Japan, where it provides intelligent guided tour services at the South Plaza of the pavilion. For a buyer, that deployment matters less as a headline than as evidence of the role the robot is designed for, namely sustained, public-facing guidance in a busy venue with a varied audience.

An interaction model with legs

Two technologies define the Walker C. The first is UBTECH's self-developed Embodied Interactive Large Model, which drives its conversations and supports multilingual interaction in exhibition halls and office buildings. Combined with a customised database for questions and answers, it allows the robot to respond with information specific to the venue rather than generic replies. The second is the U-SLAM Navigation System, which enables the robot to position its tour routes autonomously, supported by AI-powered obstacle detection and perceptive adaptation to a dynamic business environment. The result is a robot that does not wait at a fixed point for visitors to approach: it greets them proactively and then walks with them.

What makes the Walker C different from a wheeled reception robot?

Most service robots in lobbies and showrooms roll on a wheeled base and carry a screen at chest height. That design is practical, but it places the interaction on a display and limits the robot to the kind of floor a wheeled base handles comfortably. The Walker C takes a different approach. It stands 163cm tall, so it meets adult visitors close to eye level, and it moves on two legs with all-terrain speedy walking and a steady running pace of 6 km/h. Its 20 degrees of freedom and arms with a 500mm wingspan give it the posture and gestures of a human guide, which makes pointing out an exhibit or indicating a corridor feel natural rather than mechanical.

The humanoid form is not only a matter of presence. In a guided tour, the guide's body is part of the message: turning towards a display, walking ahead at a comfortable pace, pausing at the next stop. A legged humanoid with autonomous route positioning can perform that choreography, while its multilingual large model handles the spoken part. For organisations whose brand depends on a memorable visitor experience, that combination is the reason to choose a humanoid over a kiosk or a wheeled platform. Where the priority is long, uninterrupted shifts on flat floors rather than a human-scale presence, a wheeled machine such as the UBTECH Cruzr 1S Intelligent Commercial Service Wheeled Humanoid Robot deserves a place in the comparison.

How does the Walker C guide visitors on its own?

Guidance begins with knowing where the robot is and where it is going. The U-SLAM Navigation System builds the basis for autonomously positioned tour routes, and the high-precision inertial measurement unit supports the balance a bipedal robot needs while walking. Because visitor areas rarely stay still, AI-powered obstacle detection lets the Walker C adapt to people, displays and furniture that move during the day.

Conversation is the other half. The Embodied Interactive Large Model gives the robot multilingual interaction, and the customised database Q&A support means operators can load the facts visitors actually ask about: opening times, room locations, product ranges or the story behind an exhibition. Proactive greeting means the robot starts the exchange itself. For teams that want to go further, the Joint Control Interface and the Communication Interface, together with WiFi and Bluetooth connectivity, open the platform to integration with existing systems and custom behaviours.

Who is the Walker C for?

The clearest fit is the operator of an exhibition hall, museum, trade fair stand or national pavilion who needs a guide that draws visitors in and then gives them something worthwhile. The Expo 2025 Osaka deployment shows exactly that use. Corporate headquarters and multi-tenant office buildings form a second group: here the Walker C works as a reception host, greeting guests, answering questions from a customised database and walking them towards meeting areas.

A third group consists of innovation centres, universities and system integrators who value the open Joint Control Interface and Communication Interface as a basis for research or bespoke applications. Showrooms and flagship stores make up a fourth, where a humanoid guide reinforces a technology-forward brand.

Buyers should weigh the working hours honestly: the robot walks for 2h or stands for 4h on a charge, with a charging time of 1.5h, so a full day of guiding calls for planned charging breaks. UBTECH also offers the UBTECH Walker C1 Humanoid Service Robot, and Robots Europa is happy to set the two side by side for your application.

What is the Walker C used for?

1. Guided exhibition tours leading visitors along autonomously positioned routes and explaining each stop.
2. Corporate reception greeting guests proactively in the lobby and directing them to the right place.
3. Multilingual visitor information answering international audiences in their own language through the large model.
4. Venue-specific Q&A drawing on a customised database for facts about the building, brand or collection.
5. Trade fairs and pavilions acting as an attention-drawing host that turns footfall into conversations.
6. Research and integration projects using the open joint control and communication interfaces for custom development.
