UBTECH Walker C Commercial Reception Humanoid Robot

Design and Features

Humanoid form factor and actuation

Walker C adopts a human-scaled bipedal design aimed at comfortable interaction in public spaces. The robot uses 20 integrated joints across the legs and arms for essential whole-body motion, with an emphasis on stable walking, gesturing, and object pointing during tours or presentations. Compared with earlier Walker family entries, Walker C prioritizes reception-grade mobility over high-agility research locomotion. 

Perception and interaction

The sensor suite combines two RGB-D modules and two structured-light 3D cameras mounted to provide near-field depth, obstacle detection, and person tracking for HRI (human–robot interaction). UBTECH highlights all-scenario binocular vision for robust depth cues in bright expositions or indoor office lighting. The dialogue system is backed by UBTECH’s Embodied Interactive Large Model, enabling multilingual Q&A, scripted tour guidance, and context-aware introductions for exhibits or facilities. 

Autonomy and navigation

Walker C is designed for autonomous tours and station-to-station guidance. Public spec summaries describe support for indoor wayfinding and obstacle avoidance over smooth flooring typical of lobbies and halls. While UBTECH does not publish detailed SLAM stack specifics on the public page, Walker family materials point to vision-centric navigation and planner integration consistent with service-robot deployments. 

Power system and operating time

The robot is powered by a 48 V, 15 Ah lithium battery. UBTECH lists ~1.5 h charging time, ~2 h walking time, and ~4 h standing time, values that are typical for full-height service humanoids performing low-to-moderate duty cycles (tour guiding, greetings, and photo opportunities). 

Technology and Specifications

• Height: 163 cm

• Weight: 43 kg

• Degrees of freedom: 20 DoF (integrated joints; arms and legs prioritized for service motion)

• Battery: 48 V 15 Ah lithium pack

• Operation (per charge): ~2 h walking, ~4 h standing, ~1.5 h charge

• Vision sensors: RGB-D ×2, structured-light 3D cameras ×2, all-scenario binocular array

• Computing & AI: UBTECH Embodied Interactive Large Model for multilingual interaction; developer materials mention open joint-control interfaces for integration and customization

• Interfaces: Joint control interface and communication I/O (for external systems, wi-fi, or venue integration—details vary by bundle) 

Additional third-party directories tracking service robots broadly corroborate the 1.63 m size class, 20-DoF actuation, and 2–4 h runtime envelope common to exhibition and reception use cases. Some listings also note walking speeds up to ~6 km/h for venue transits, though final behavior and limits are deployment-specific. 

Applications and Use Cases

Guided tours and reception

Walker C’s primary role is greeter and guide: welcoming visitors, introducing exhibits, and escorting groups along pre-planned routes. The multilingual model allows switching languages mid-session, which is useful at international expos and corporate lobbies.

Corporate communications and events

In product launches and enterprise events, Walker C can present talking points, gesture to displays, and provide hands-free navigation assistance from reception to auditorium seating, improving flow and engagement in high-footfall venues. 

Office buildings and public halls

For day-to-day operation, the robot can perform visitor check-ins, wayfinding, and FAQ answering, while collecting anonymized utilization metrics for facilities management (depending on local policy and configuration).

Education and outreach

Museums and science centers use humanoid robots as STEM outreach tools. Walker C’s life-size presence, combined with safe, slow gestures, can increase audience attention during demonstrations. 

Advantages / Benefits

• Human-scaled interaction: Full height (163 cm) and arm gestures improve visibility and perceived presence in crowded lobbies and halls.

• Multilingual embodied AI: UBTECH’s Embodied Interactive Large Model supports natural, multilingual dialogue for tours and Q&A. 

• Lightweight for class: 43 kg is relatively low mass for a full-size humanoid, easing transport/setup and reducing floor-load constraints. 

• Purpose-built runtimes: 2 h walking / 4 h standing match typical reception and guided-tour shifts with scheduled charging windows. 

• Service-ready sensors: Multiple RGB-D / structured-light modules aid close-range obstacle detection and person tracking in indoor lighting. 

Comparisons (if relevant)

• Walker C vs. Walker (earlier family entry): The earlier Walker showcased 36 DoF and broader household/office concepts at a shorter 145 cm height and higher mass (77 kg). Walker C focuses on 20 DoF service motions, full-height 163 cm, and multilingual embodied AI tailored to commercial venues. 

• Walker C vs. Walker X (R&D showcase): Walker X materials emphasize upgraded hand–eye coordination and research demonstrations of advanced autonomy. Walker C is positioned as a ready-to-deploy reception/tour platform for real venues.
