What it is

Walker S2 is the all-new full-size industrial humanoid robot launched by UBTech Technology on July 23, 2025. It stands 176 cm tall, weighs 70 kg, and has 52 degrees of freedom across its body, and can carry a 15 kg payload anywhere within the full 0–1.8 m range. Its headline feature is the world's first hot-swappable autonomous battery-swap system: original dual-battery power-balancing technology combined with dual-arm coordinated precision battery swapping completes an autonomous swap in 3 minutes without human intervention, enabling uninterrupted 7×24-hour operation.

Highlights

01The world's first humanoid robot to achieve hot-swappable autonomous battery swapping: 3-minute swaps and 7×24 continuous operation
02China's first humanoid robot to use a pure RGB binocular vision system in the head
0352-DOF bionic body with ±162° waist rotation and 15 kg payload handling across the 0–1.8 m workspace
04Began mass-production deliveries of the first several hundred units in November 2025, with full-year orders exceeding CNY 1.4 billion
