It stands 1.7 m tall with 41 force-feedback servo joints, and its successors Walker S1 and S2 work on car assembly lines and in logistics. UBTECH is listed in Hong Kong.","sections":[{"h":"History and launch","p":["Walker S made its public debut on 29 December 2023 when UBTECH listed on the main board of the Hong Kong Stock Exchange: the robot struck the opening gong alongside chairman Zhou Jian. UBTECH called it the first listing ceremony with a humanoid and itself the first humanoid company on the exchange's main board.","Later versions are Walker S1, adapted to car assembly lines, and Walker S2, which swaps its own battery. The Walker S series builds on UBTECH's earlier Walker and Walker X humanoids."]},{"h":"Hardware","p":["UBTECH lists Walker S at 1.7 m with 41 servo joints with force feedback. Force-compliant joints and a hybrid rigid-flexible structure are meant to keep it stable even on moving production lines. It carries high-resolution RGBD cameras plus audio and distance sensors.","Walker S2 lifts 15 kg according to UBTECH, and a high-torque waist lets it rotate ±162° and bend 125°, working anywhere from 0 to 1.8 m high. It uses passive RGB-only stereo vision and two batteries: it can swap a battery on its own in about 3 minutes and choose between swapping and charging, aiming at round-the-clock work."]},{"h":"Software and AI","p":["Walker S uses U-SLAM navigation with 3D semantic maps, estimates the 6D pose of objects from point clouds and grasps them with hand-eye coordination. It integrates a large language model for intent understanding and task planning, runs the ROSA 2.0 operating system and can link to manufacturing management systems to exchange production data. UBTECH also develops an industrial agent, Co-Agent, for Walker S2."]},{"h":"Use cases and deployments","p":["UBTECH says Walker S1 works on car-factory assembly lines alongside autonomous logistics vehicles and AMRs/AGVs. In 2025 the company sold 1,079 full-size humanoids (over 160 cm, not remote-controlled) for RMB 820 million, with total revenue above RMB 2 billion.","In 2026 UBTECH signed European integrator Terra Robotics as exclusive distributor for Germany, Switzerland and Austria. Terra bought several dozen humanoids that are being deployed in settings including ROSSMANN logistics centres, where Walker S2 handles material moving and sorting."]},{"h":"Manufacturer","p":["UBTECH Robotics was founded in Shenzhen in 2012; Zhou Jian is chairman and CEO. It began with small educational and entertainment robots (the Alpha series) and also makes Cruzr service robots and AI education platforms. It has been listed in Hong Kong since December 2023 (9880.HK) and joined the HKEX Tech 100 index in 2026."]},{"h":"Price and availability","p":["UBTECH does not publish Walker S series prices; sales go through its sales team and partners such as Terra Robotics in Europe."]}],"timeline":[["2023-12","Walker S debuts at UBTECH's Hong Kong listing."],["2025","UBTECH sells 1,079 full-size humanoids."],["2026-07","Partnership with Terra Robotics; robots in ROSSMANN logistics."]],"faq":[["How much does UBTECH Walker S cost?","UBTECH does not publish a price."],["Where does Walker S work?","Walker S1 on car-factory assembly lines; Walker S2 in places such as ROSSMANN logistics centres in Europe."],["How much can Walker S2 lift?","15 kg according to UBTECH."],["Does Walker S2 swap its own battery?","Yes, UBTECH says it swaps a battery autonomously in about 3 minutes."],["How many humanoids has UBTECH sold?","1,079 full-size humanoids in 2025."]],"sources":[{"title":"UBTECH Walker S industrial humanoid robot","publisher":"UBTECH Robotics","url":"https://www.ubtrobot.com/en/humanoid/products/walker-s","date":"2026-10"},{"title":"UBTECH Walker S1 humanoid robot","publisher":"UBTECH Robotics","url":"https://www.ubtrobot.com/en/humanoid/products/walker-s1","date":"2026-10"},{"title":"UBTECH Walker S2 humanoid robot","publisher":"UBTECH Robotics","url":"https://www.ubtrobot.com/en/humanoid/products/walker-s2","date":"2026-10"},{"title":"As Walker S Strikes the Gong, UBTECH Robotics Becomes the First Humanoid Robot Company Listed on the Main Board of the HKEX","publisher":"UBTECH Robotics","url":"https://www.ubtrobot.com/en/about/news/498762019606597","date":"2023-12-30"},{"title":"UBTECH partners with collaborators to accelerate global expansion, bringing humanoid robots to European retail logistics environments","publisher":"UBTECH Robotics","url":"https://www.ubtrobot.com/en/about/news/826574022332485","date":"2026-07-13"}],"updated":"2026-10-10"},"mera":{"rental_with_operator":false,"sale_in_offer":false,"availability":"confirmation_required","shop_url":null},"url":"https://merarobotics.com/blog/humanoids/ubtech-walker-s","inquiry_url":"https://merarobotics.com/en/start?service=purchase&robot=ubtech-walker-s"}
