On July 17, 2025, UBTech officially unveiled the Walker S2, its next-generation industrial humanoid robot, featuring the world's first hot-swappable autonomous battery-swapping system. Leveraging three core technologies, the system enables 7x24 uninterrupted operation, creating a new "non-stop" productivity engine for smart manufacturing.
The system builds on three technical advantages:
Dual-battery power balance: Real-time monitoring of battery levels and dynamic power allocation support simultaneous charging and discharging of dual batteries, as well as hot-swappable battery replacement while powered on, mitigating current surge risks and ensuring operational stability;
Standardized battery compartment quick-swap: Battery modules are integrated into the robot's structural design, with zero-gap compartment alignment and self-aligning grippers enabling flexible switching between dual-battery long-range mode and single-battery mode;
Dual-arm collaborative precision alignment: Leveraging body positioning accuracy and compliant control algorithms, the system achieves millimeter-level alignment between the battery and the compartment, autonomously completing the battery swapping process.
These technological breakthroughs directly empower industrial applications: On one hand, autonomous battery swapping eliminates the need for downtime or manual intervention, eliminating production interruptions and significantly improving efficiency; on the other hand, the physical isolation of hot-swappable batteries, rapid power-off mechanisms, and dual-battery redundant backup systems reinforce safety measures in factory operations. Currently, Walker S2 has achieved dynamic energy management through "autonomous decision-making for charging and swapping based on task priority," accelerating the penetration of humanoid robots into full-time industrial application scenarios and driving smart manufacturing into a new era of continuous operations.
