Overview
Built by UBTECH Robotics of Shenzhen, China, the Walker S2 is a humanoid whose named customers include BYD, Foxconn and FAW-Volkswagen. A UBTECH press release on 17 November 2025 announced mass production and delivery, citing cumulative orders above CNY 800 million since early 2025.
It is shipping. UBTECH has not published an official price. Retailer RobotShop's EU listing shows €242,000 including tax, with shipping calculated at checkout, and marks the robot as on demand.
Its clearest maker-stated feature is an autonomous hot-swappable battery that the robot exchanges itself within 3 minutes. It can lift 15 kg within a 0–1.8 m workspace, and vision relies on a self-developed passive binocular RGB stereo system. Other figures come from reports. IT Home gives a height of 1.76 m and 52 degrees of freedom, well above the 29 median across humanoid records, though one SDK document states 42. 21jingji reports 2 m/s walking and 11-DoF hands. A UBTECH brochure hosted by retailer Funduino lists 70 kg, a 7.5 kg single-hand grasp and four microphones. Runtime, battery capacity, charge time and the processor are not published.
