Walker S Humanoid Robot

Walker S represents UBTech’s industrial-grade humanoid robot platform, designed for sophisticated manufacturing environments and commercial service applications. Standing 1.7 meters tall with 41 servo joints featuring force feedback, the Walker S series has evolved through multiple iterations (S, S1, S2) to become one of the most commercially deployed industrial humanoid robots globally.

Product Overview

The Walker S series originated from UBTech’s consumer-oriented Walker platform but has been specifically engineered for industrial applications. Unlike research-focused humanoid robots, Walker S prioritizes practical deployment in factory assembly lines and service environments. The robot’s modular design allows customization for different industrial tasks while maintaining human-like proportions for direct integration into workspaces designed for people.

Walker S2, launched in November 2025, represents the latest generation with mass production capabilities. The robot has been deployed at automotive factories including Geely’s Zeekr smart factory, where multiple Walker S2 units conduct coordinated tasks across different manufacturing scenarios.

Key Features

Walker S’s world-first autonomous hot-swappable battery system enables continuous factory deployment with exchanges completed in under three minutes.

Full-Stack Sensing System: Equipped with high-resolution RGBD visual sensors, the robot creates 3D semantic maps for navigation while detecting and avoiding obstacles. Multiple visual, audio, and distance sensors enable broad environmental perception.

Force-Compliant Motion: The rigid-flexible coupling hybrid structure with force-compliant drive joints enables stable walking on mobile production lines and safe human-robot interaction.

Autonomous Battery Management: Walker S2 features the world’s first autonomous hot-swappable battery system for humanoid robots, completing battery exchanges within 3 minutes using dual-arm coordinated precision swapping technology.

AI Integration: Large language model (LLM) integration enables complex intent understanding and fine-tuned action planning. The BrainNet 2.0 and Co-Agent dual-loop AI system supports both single-robot autonomy and multi-robot swarm intelligence.

Technical Specifications

Walker S’s 41 force-feedback servo joints and 15 kg payload capacity define its industrial-grade profile for factory and healthcare environments.

Product Variants

Walker S

The original industrial version featuring force-compliant joints and full perception systems for factory assembly line operations.

Walker S1

Launched October 2024, Walker S1 introduced end-to-end learning-based whole-body motion control for enhanced dexterous manipulation. Specifically designed to solve three key industrial challenges: visual positioning under varying conditions, motion control under dynamic high-load situations, and joint cooling during extended operations.

Walker S2

The mass-production version (November 2025) with autonomous battery swapping, 15kg payload capacity, and advanced waist articulation. The first humanoid robot to achieve large-scale manufacturing deployment.

Walker S Lite

A lightweight variant designed for intelligent manufacturing and smart logistics with rapid deployment capabilities.

Clinical Applications

While not a medical device requiring regulatory approval, Walker S has been adapted for healthcare and elderly care environments:

Elderly Care Facilities: Deployed at nursing homes for companion services, assisted mobility, and routine monitoring. The smart elderly care solution integrates Walker-based systems with IoT platforms for thorough resident care.

Hospital Services: In partnership with Hong Kong University Shenzhen Hospital and China Unicom, Walker S systems have been deployed in smart ward solutions, providing patient assistance and autonomous delivery services.

Rehabilitation Support: The robot’s stable locomotion and precise manipulation capabilities support post-operative rehabilitation scenarios, delivering meals, providing companionship, and facilitating mobility exercises.

Regulatory Status

Walker S series products are classified as industrial and commercial service robots rather than medical devices. As such, they do not require NMPA, CE, or FDA medical device approvals. Deployment in healthcare facilities occurs under commercial equipment regulations rather than medical device frameworks.

Frequently Asked Questions

What is the price of Walker S?

UBTech has not publicly disclosed specific pricing for Walker S series robots. Industrial humanoid robots typically command premium prices due to advanced componentry and customization requirements. Enterprise pricing is negotiated based on deployment scale and configuration requirements.

Can Walker S be used in hospitals?

Walker S has been deployed in hospital settings for non-medical functions including patient guidance, delivery services, and companion roles. The robot operates under commercial equipment classification rather than as a medical device, suitable for service tasks that do not require direct medical intervention or diagnostic functions.

How does Walker S compare to Tesla Optimus?

Walker S2 has achieved mass production and commercial deployment in automotive factories, while Tesla Optimus remains in development and demonstration phases. Walker S features 41 force-feedback servo joints compared to Optimus’s design specifications, with proven industrial deployment across multiple manufacturers.
