Chinese robotics firm UBTech has unveiled the Walker S2, the world’s first humanoid robot capable of autonomously swapping its own battery without human intervention. The robot can complete a battery replacement in approximately three minutes, enabling continuous 24/7 operation without shutdowns. This hot-swappable autonomous battery system represents a notable advancement in industrial robotics, allowing the Walker S2 to maintain uninterrupted work cycles on factory lines and other dynamic industrial environments. The technology reduces downtime and labor costs associated with battery maintenance. UBTech, based in Shenzhen, China, demonstrated the robot's smooth movements and battery-swapping capabilities in a Zeekr car factory. The Walker S2’s autonomous battery swap system is expected to extend operating hours for service robots and improve efficiency in manufacturing and other sectors.
