UBTech unveils the Walker S2, an industrial humanoid that swaps its own battery in three minutes without shutting down, enabling 24/7 work. It lifts 15 kg and becomes the brand's mass-production model.

What changes

  • The first humanoid able to swap its own battery, according to UBTech.
  • 3-minute swap without shutdown, thanks to a dual battery.
  • The robot chooses between charging and swapping based on task priority.
  • 15 kg payload and a 0 to 1.8 m workspace.

### Background On July 17, 2025, UBTech (Shenzhen, listed in Hong Kong) showed the Walker S2, the new generation of its industrial humanoid. Its distinctive feature: it replaces its own battery, without human help or shutdown. The press reported a "launch" a few days later; the date used is that of the video and the first verified coverage. ### Specifications | Item | Announced value | |---|---| | Battery swap | autonomous, in 3 minutes, without shutdown | | Power | dual battery with dynamic balancing, switches to the backup battery on failure | | Management | chooses between charging and swapping based on task priority | | Payload | 15 kg | | Waist | ±162° rotation, 125° pitch | | Workspace | 0 to 1.8 m | | AI | BrainNet 2.0 and the Co-Agent industrial platform | UBTech presents the Walker S2 as "the world's first humanoid robot capable of autonomous battery swapping". ### Why it matters Endurance is one of the main barriers for humanoids in factories. By removing charging downtime, UBTech targets 24/7 operation on its customers' lines; Nio, BYD and Zeekr tested earlier Walker generations on their assembly lines. ### Key takeaways The Walker S2 became UBTech's series model: mass production and deliveries began in November 2025, with more than 800 million yuan in orders.
