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.
Unitree G1
The Unitree G1 is a research and developer humanoid platform at a sub-enterprise price point, sold into university labs, hardware-research groups, and individual developers rather than enterprise integration contracts. The category distinction matters: a G1 at a research bench is in its intended environment; treating G1 in active research use as commercial deployment overstates Unitree's commercial position relative to Apollo, Digit, or Atlas. Unitree describes G1's autonomy as developer-platform capability for capability research, with the published specs (degrees of freedom, payload, runtime) as the verifiable substance; commercial deployment hours at named customer sites are not yet part of G1's record.
