Walker S1 was launched in October 2024 and trialled in factories: quality inspection at the Audi-FAW New Energy Vehicle plant in Changchun, logistics at Foxtron's Longhua site (Foxconn), and sorting at BYD. UBTECH announced plans for 500 to 1,000 Walker S-series units in 2025. The Walker S2 is the current flagship; the S1 is kept here as the documented deployment record.
Our verdict
Many named factory trials in China, little detail on scale or economics; read the customer list as pilots, not volume.
