The Walker C's dimensions are its service philosophy. At 163 centimeters and a light 43 kilograms, it stands at natural conversational height, tall enough for eye level engagement, light enough for inherent safety among crowds, with 20 degrees of freedom producing the fluid gestures, expressive body language and confident walking, at speeds up to 6 kilometers per hour, that make interaction feel met rather than operated. Where its industrial siblings in the Walker S line are built for torque and tooling, the Walker C is built for the moment a visitor decides how they feel about a place.

Positioned in UBTECH's commercial range beside the wheeled Cruzr line and within the wider humanoid lineup, the UBTECH Walker C for sale, with full specifications, can be explored through this page.

What Defines the Walker C

A Guide Powered by an Embodied Large Model

The Walker C's mind is UBTECH's self developed Embodied Interactive Large Model: multilingual dialogue, emotional expression and adaptive narration fused with the robot's body, so answers arrive with gesture, stories adjust to the audience and the tour flows as conversation rather than playback. The model carries the robot's core services, interactive Q&A, broadcasting and AI storytelling, in the languages international venues actually receive.

Reception and Tours as Its Native Work

The Walker C's role set is front of house complete: proactive greeting and welcome at the door, guided tours along planned routes with stop by stop narration, group escort through exhibitions and offices, and photo moment charisma between duties, the greeter and guide roles validated from music venue appearances to its Expo 2025 Osaka posting, where it served as the China Pavilion's embodied AI tour guide before a global audience.

Walking Built for Public Floors

Bipedal service demands more than balance, it demands composure in crowds, and the Walker C delivers it: all terrain walking with obstacle avoidance at up to 6 kilometers per hour, whole body motion control keeping movement smooth and predictable among visitors, strollers and photographing guests, the gait discipline that lets a walking robot share a busy exhibition floor safely.

Sized for Safety, Built for Presence

The 43 kilogram build is a deliberate service specification: substantial enough for presence, light enough that safety among the public is architectural rather than procedural, with 500 millimeter wingspan arms weighing 5 kilograms delivering expressive gesture, the physicality of a machine designed from the first sketch to work rooms full of people.

Technology and Specifications

Perception for Crowded Rooms

The Walker C sees through a doubled vision stack: two RGB-D cameras and two all scenario binocular structured light 3D cameras, fused with a high precision inertial measurement unit, delivering the depth perception, person tracking and environmental awareness that guide work requires, the visitor followed, the obstacle anticipated, the route held through the crowd.

U-SLAM Navigation and Semantic Mapping

Autonomy runs on UBTECH's U-SLAM: autonomous path planning, semantic 3D mapping and safe indoor movement, the same navigation lineage proven across the company's global service fleet, applied to tour routes, venue transits and the moment to moment negotiation of public space.

Power for the Service Day

A 48 volt, 15 amp hour battery charges in roughly 1.5 hours and sustains around 2 hours of walking duty or 4 hours of standing service, the duty cycle of reception and tour work, greeting posts, scheduled tours, engagement sessions, managed across the venue day with charging windows between.

Open for Venue Integration

The platform ships integration ready: open joint control and communication interfaces, WiFi and Bluetooth connectivity and API access for enterprise links, letting the Walker C synchronize with exhibition systems, navigation infrastructure and venue automation, the robot as a connected member of the building's stack rather than a standalone attraction.

Applications and Use Cases

Exhibitions, Expos and Museums

The proven flagship role: guided tours, exhibit narration and international visitor engagement across exhibition robotics, with the Expo 2025 Osaka China Pavilion posting as the category's most public reference.

Office Buildings and Corporate Reception

Office lobbies deploy the Walker C for greeting, visitor guidance and building tours, the walking receptionist whose presence announces a company's posture toward the future.

Hotels and Hospitality

Across hotel and reception programs, the Walker C carries arrival welcome and property tours, the humanoid warmth tier above the property's delivery and cleaning fleet.

Retail, Malls and Public Venues

Retail flagships, malls and civic buildings run greeting, wayfinding and engagement duties through the crowds its perception stack was built for, within the wider commercial robotics world.

Brand Moments and Events

From music scene appearances to launch activations, the Walker C serves as embodied brand presence, the walking, talking, gesturing ambassador venues book when the moment must be remembered, alongside the humanoid category's most photographed peers.

Frequently Asked Questions

What is the UBTECH Walker C?

The Walker C is UBTECH's full size reception and tour guidance humanoid: a 163 centimeter, 43 kilogram electric driven biped with 20 degrees of freedom, powered by the company's Embodied Interactive Large Model for multilingual interaction, serving greeting, guided tour and visitor engagement roles across commercial venues.

How does the UBTECH Walker C work?

The Walker C navigates by U-SLAM with semantic 3D mapping, perceives through dual RGB-D and dual structured light 3D cameras with a precision IMU, walks at up to 6 kilometers per hour with obstacle avoidance, and interacts through multilingual dialogue, adaptive narration and expressive gesture, integrating with venue systems through open joint control and communication interfaces.

Why is the UBTECH Walker C important?

It converted the bipedal humanoid from spectacle to service: a walking guide light enough for crowd safety, intelligent enough for adaptive multilingual tours and proven enough to represent the China Pavilion before Expo 2025's international audience, the reference deployment for humanoid front of house work.

What are the benefits of the UBTECH Walker C?

Key benefits include eye level humanoid presence at inherently safe weight, large model driven multilingual interaction with emotional expression, confident 6 km/h walking through real crowds, doubled depth vision with U-SLAM navigation, open venue integration interfaces and the deployment pedigree of UBTECH's global commercial program.

How long does the Walker C operate per charge?

The 48 volt, 15 amp hour battery delivers roughly 2 hours of walking duty or 4 hours of standing service per charge, recharging in about 1.5 hours, a cycle matched to reception posts, scheduled tours and engagement sessions across the venue day.

How is the Walker C different from the Cruzr?

Form and moment: the Cruzr is the wheeled service veteran for high volume, long duty reception and promotion, while the Walker C brings full bipedal presence, walking tours, expressive gesture, eye level engagement, to the venues where the humanoid itself is part of the experience, with many programs deploying both tiers together.

Where can I buy the UBTECH Walker C and what does it cost?

The Walker C is for sale through Robots International, serving markets worldwide with delivery, customs clearance and support. Because cost varies by configuration and integration scope, buyers should request a tailored quotation. Full purchasing details are available on this page.
