Editorial summaries
Walker S2
The Walker S2 is UBTech's enterprise humanoid, with verified factory pilots at BYD, FAW-Volkswagen, Foxconn, Geely, NIO, and Zeekr in China. UBTech is publicly traded on the Hong Kong exchange. The Walker S2 is not sold to consumers; the editorial position is honest-absence on consumer pricing.
XPeng IRON
XPeng's IRON (from the Chinese EV maker XPeng) is a roughly 175-centimeter, 70-kilogram research humanoid, an automotive-OEM entrant into humanoids, the cross-OEM positioning that parallels Tesla Optimus emerging from a carmaker. DEPLOY records it at research maturity with no verified deployments. XPeng has shown IRON in staged demonstrations and stated consumer and industrial intentions, but the verification posture is demonstration, not verified autonomous deployment or commercial sale, and DEPLOY cap-flags aggregator 'autonomous' or 'shipping' framing. As a research platform it has no consumer price.
