Walker C

The UBTECH Walker C is a full-size, electric-driven embodied intelligent humanoid robot designed primarily for commercial service applications such as wayfinding, reception, visitor support, and interactive tour guiding in environments like exhibition halls, office buildings, shopping malls, transport hubs, and public zones. Standing at 163 cm tall and weighing 43 kg, it features 20 degrees of freedom (DoF) distributed across its bipedal structure, enabling stable walking at up to 6 km/h, multi-joint articulation for human-like gestures, dancing, and pointing. Its lightweight arm wingspan measures 500 mm per arm, with each arm weighing 5 kg, optimized for gesturing rather than heavy manipulation. Architecturally, Walker C integrates a comprehensive sensory suite for perception and navigation: two RGB-D cameras for near-field depth and person tracking, two all-scenario binocular structured-light 3D cameras for robust depth mapping in varied lighting, and a high-precision Inertial Measurement Unit (IMU) for balance and orientation. The U-SLAM (Simultaneous Localization and Mapping) navigation system enables autonomous positioning, route planning, obstacle avoidance, and adaptation to dynamic crowds, supporting indoor wayfinding over smooth floors. Connectivity includes Wi-Fi, Bluetooth, and open interfaces for joint control and communication, facilitating integration with external systems. At its core is UBTECH's proprietary Embodied Interactive Large Model (EILM), a multimodal AI framework that fuses vision, language, voice, and motion for natural human-robot interaction. This self-developed large language model (LLM) supports multilingual dialogue (switchable mid-session), proactive greetings, customized Q&A from databases, adaptive narration as an AI curator, speech understanding, and context-aware responses. It powers whole-body motion control, enabling steady running, perceptive environmental adaptation, and entertainment features like voice broadcasting and dance performances. While specific compute hardware like CPU/GPU remains undisclosed for Walker C, related UBTECH models use Intel i7 processors (e.g., i7-8665U or i7-7500U) paired with NVIDIA discrete GPUs, suggesting similar edge computing for low-latency glass-to-action performance. Power is provided by a 48V 15Ah (0.72 kWh) lithium-ion battery, offering 1.5 hours charge time, 2 hours walking runtime, and 4 hours standing operation, suitable for shift-based deployments with manual swapping. No advanced thermal management or IP rating is specified, aligning with indoor prototype status. Real-world deployment history underscores its commercial viability. In April 2025, Walker C debuted as the first embodied AI 'Tour Guide' at the China Pavilion during Expo 2025 Osaka, Kansai, Japan, on Yumeshima Island, welcoming visitors, providing multilingual guides, handshakes, high-speed walking demos, and navigating crowds—rivaling Unitree's G1 in autonomy. It also appeared at the Strawberry Music Festival 2025 for fan greetings, the Spring Banquet of Guangdong Province 2025 in Hong Kong for guest welcomes and tech showcases, and World Robotics Conference (WRC) 2025 among five UBTECH humanoids. These pilots highlight reliability in public, high-interaction settings, with metrics collection for optimization. As a prototype (priced ~$30,000-$100,000 via resellers), it bridges research (e.g., Walker X) and industrial scales (Walker S series), emphasizing service over heavy labor, with 10-fingered hands for basic interaction. Future iterations may enhance manipulation and runtime amid UBTECH's mass-production push.
