Editorial summaries

Astribot S1

The Astribot S1, from China's Astribot (Shenzhen), is a research humanoid that drew wide attention for fluid bimanual manipulation demonstrations (folding clothes, pouring, handling objects). There is no verified consumer price or delivery date on record, and the manipulation footage is demonstration material, not evidence of verified autonomous deployment. DEPLOY classifies its maturity as research and applies verified-vs-claimed discipline: the demos are impressive claims; verified deployment and pricing are absent.

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.
