About Walker C

Walker C is UBTECH's full-size electric humanoid for guiding and public-facing service in exhibition halls, offices, service centres, shopping centres and transport hubs. Its embodied interaction model supports multilingual conversation, customised question answering, proactive greetings and narrated tours.

U-SLAM builds routes through a venue, while cameras and obstacle detection support autonomous movement around visitors. The 163-centimetre, 43-kilogram robot has 20 degrees of freedom, RGB-D and binocular structured-light cameras, joint-control interfaces and a walking runtime of about two hours. Walker C served as an AI guide at the China Pavilion during Expo 2025 Osaka and is offered with customised content and service workflows.

Context

Market context

Walker C is a service-facing humanoid for public environments such as reception, exhibitions, and guided interaction.

  • Target environment: Research labs, industrial pilots, service demonstrations and structured environments where humanoid hardware can be tested or deployed.
  • Workflow context: Locomotion, manipulation, human-robot interaction, embodied AI testing and task execution in controlled settings.
  • Customer context: Robot developers, research teams, industrial partners and service operators evaluating humanoid systems.
  • Deployment model: Prototype or development-stage product with public positioning and limited deployment proof.
  • Commercial maturity: Publicly visible but still early, with maturity tied to demos, pilots and later customer evidence.
  • Adoption constraints: Adoption depends on safety, useful task coverage, manipulation reliability, operating time, support and proof outside demonstrations.
  • Market position: UBTECH Robotics positions Walker C in the humanoid lane, where body format, autonomy and task evidence determine differentiation.
