Company Claim

UBTECH names BYD, Dongfeng Liuzhou Motor, Geely Auto, FAW-Volkswagen Qingdao, Audi FAW, BAIC New Energy, Foxconn, and SF Express as Walker S2 customers, with orders exceeding 800 million yuan (~$112 million) since early 2025, and states it is scaling production capacity to 5,000 units/year by 2026 and 10,000/year by 2027

What's Actually Confirmed

Task-level, site-specific confirmation of S2 hardware (as opposed to earlier Walker S/S1/Lite generations) is only independently traceable for Foxconn, where UBTECH's own industrial solutions page describes Walker S2 working alongside its Wali U1500 AMR for SPS parts feeding. For other named customers, UBTECH's own materials describe their earliest humanoid trials using predecessor models (Walker S1 at BYD, Walker S Lite at FAW-Volkswagen, plain 'Walker S' at NIO), and it is not independently confirmed whether each has since received S2-specific units as part of the November 2025 order book
