UBTech Robotics has unveiled the Walker S2, the world’s first capable of fully autonomous battery swapping. This robot is the first in the world to be able to swap its own battery without human help. The company says this new feature means the robot can work non-stop, 24 hours a day, seven days a week, in busy industrial environments.
In a video demonstration, Walker S2 is seen walking steadily towards a charging station, carefully removing a depleted battery from its chest, placing it in a dock, and sliding a fully charged replacement into place. The entire process takes just three minutes, showing a level of precision and independence rarely seen in humanoid robotics.
“This is a significant step forward for factory intelligence and automation,” a UBTech spokesperson said. “With Walker S2, we’re showing that robots can work non-stop, manage their own power, and support industries that rely on 24/7 operations.”
The Walker S2 is designed with advanced bipedal locomotion and an intelligent battery system that allows it to swap batteries on its own. But that’s not all. The robot also has a dual-battery power balancing system. This means it can switch to a backup battery instantly if the main one fails, ensuring that critical tasks continue without interruptions.
UBTech explains that Walker S2 can even decide whether to recharge or swap batteries based on how urgent its current tasks are. This level of energy management gives factories more flexibility and less downtime, especially in industries where delays can mean big losses.
“The ability to adapt energy use in real-time is a game changer,” said an engineer at UBTech. “Factories can now trust robots to manage themselves, even in complex environments.”
UBTech partnered with Huawei Technologies to help speed up the use of humanoid robots in factories and homes across China. This partnership combines Huawei’s strong technology background with UBTech’s expertise in humanoid robotics. Together, they plan to make robots like Walker S2 a common part of daily life and work.
“Robotics and AI are the future of smart factories and smart homes,” said a Huawei representative. “Our collaboration with UBTech will bring these advanced technologies into more industries and households sooner than expected.”
UBTech also introduced a system called “BrainNet,” which allows multiple humanoid robots to work together as a team. This system uses a “super brain” for big decisions and a “sub-brain” to handle real-time tasks.
The super brain uses advanced AI to plan and schedule work across an entire factory floor. The sub-brain coordinates individual robots, ensuring they adapt quickly to changes and work in perfect harmony.
At Zeekr’s 5G-enabled smart factory, UBTech showed how multiple Walker robots could perform complex tasks together. In this setup, using this system, robots moved beyond working alone. Instead, they operated like a human team. Moreover, they shared information and helped each other as needed.
Reports from financial firms like Moody’s and Morgan Stanley show that China is becoming a global leader in robotics. More than half of all companies worldwide working on humanoid robots are Chinese. Startups in the country are also attracting huge investments from global venture capital firms.
“China is emerging as a robotics powerhouse,” Moody’s noted in a recent report. “It combines advanced AI with affordable manufacturing, creating a perfect environment for innovation.”
Companies such as BYD, Nio, and Zeekr have already tested Walker S2 at their factories. “With Walker S2, we’re not just building a robot,” said UBTech’s CEO. “We’re creating a platform for a future where humans and robots work side by side, each focusing on what they do best.”
