Overview
The UBTECH Walker C is a humanoid service robot developed for environments such as exhibition halls, office buildings, service centres, shopping malls and transport hubs. We supply UBTECH platforms to corporate projects in Turkey through enterprise supply, commissioning and technical integration. Configuration, delivery terms and investment are set by corporate quotation.
The published dimensions are 163 cm and 43 kg. The battery is 48V 15Ah lithium. Through whole-body motion control the robot walks at a 6 km/h pace across all terrain, and the arm is stated at a 500 mm wingspan and 5 kg of weight.
The manufacturer presents the Walker C as the first embodied AI tour guide of the China Pavilion at Expo 2025 Osaka. A world expo pavilion is a demanding stage for a service robot: the crowd changes constantly, visitors speak different languages and the robot stays on its feet all day.
On interaction it uses the manufacturer's self-developed embodied interactive large model with multilingual support. The robot greets proactively and provides question-and-answer service through a customised database. AI-powered obstacle detection lets it adapt to a dynamic business environment.
Six deployment environments are defined: guiding in exhibition halls, greeting in office buildings, live question-and-answer in service centres, voice broadcasting in shopping malls, smart guiding at transport hubs and entertainment in public zones.
The China Pavilion at Expo 2025 Osaka
The manufacturer presents the Walker C as the first embodied AI tour guide of the China Pavilion at Expo 2025 Osaka. A world expo pavilion is a demanding stage for a service robot: the crowd changes constantly, visitors speak different languages and the robot stays on its feet all day. Taking a post in that environment is a different level of maturity from a controlled demonstration.
Six Deployment Environments
Six environments are defined: guiding in exhibition halls, greeting in office buildings, live question-and-answer support in service centres, voice broadcasting in shopping malls, smart guiding at transport hubs and entertainment in public zones. All six are face-to-face, speech-heavy roles that carry no physical load.
A Six Kilometre Pace and Terrain Adaptation
There are a 6 km/h pace and speedy all-terrain walking through whole-body motion control, with AI-powered obstacle detection and adaptation to a dynamic business environment added on top. What matters in an exhibition hall is not top speed but being able to keep moving through a crowd. Noticing a visitor, giving way and re-planning the route is the job of this layer.

Analysis of a Humanoid Exhibition Guide
Why 163 cm and 43 kg
The dimensions are not accidental. At 163 cm the robot stands near eye level with an adult without appearing threatening. At 43 kg it is light compared with industrial humanoids in the same class: the Walker S2 is 70 kg and the Unitree H2 70 kg. Lightness gains two things on a service robot, less risk in a fall and lower energy consumption. A 500 mm arm wingspan and a 5 kg arm weight also show a design for gesturing and pointing rather than carrying loads.

Engineering Assessment
The Walker C makes consistent decisions in service robot design: a height near eye level, a light body, an arm built for gesturing and a multilingual interaction model. Having taken a post on a demanding stage such as Expo 2025 Osaka shows it has not stayed on paper. Against that, the battery capacity is given but the runtime it delivers is not, and that is the first question in any trade fair or building deployment. Our recommendation to an evaluating organization is to request runtime and charging time from the manufacturer and to build the daily shift plan around them.

Walker C Frequently Asked Questions
The most commonly asked questions and answers about Walker C.
We deliver UBTECH hardware to corporate projects through enterprise supply, commissioning and engineering support. Investment is set by corporate quotation against configuration, quantity and delivery terms. With organizations evaluating a humanoid for exhibitions, reception or guiding we discuss the sourcing route and timeline per project. If you want an option deliverable today, the Unitree G1 and H2 can be ordered in Turkey.
The only known figure is that the battery is 48V 15Ah lithium, roughly 720 Wh of capacity. If you are planning a trade fair or building deployment, both figures should be requested from the manufacturer.
