First Robot Unveiled That Can Run by Itself and Change Its Own Batteries
Humanoid robots are becoming more advanced, but one recent model stands out—the Walker S2, made by Chinese company UBTECH. This robot can change its own battery, allowing it to operate nonstop. At 5’3” (162 cm) tall and weighing 95 lbs (43 kg), it’s about the size of a small adult.
The Walker S2 uses a dual-battery system with 48-volt lithium batteries. It can walk for two hours or stand for four before needing a recharge, which takes 90 minutes.
What makes it unique is its ability to swap its own batteries without human help—a feature UBTECH calls a “world first.”
In a YouTube video from July 17, the robot is shown approaching a charging station, removing its drained battery, and inserting a fresh one—all on its own.
According to UBTECH, the Walker S2 can also decide when to swap batteries based on its power levels and task priorities, as reported by CnEVPost.
Designed for factories or public spaces (like greeting customers), the Walker S2 has 20 degrees of freedom—meaning its joints can move in many ways—and supports Wi-Fi and Bluetooth.
With robots like the Walker S2 handling tasks independently, will humans soon be unnecessary? How long before robots no longer need us at all?
