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.

K2 Bumblebee

Kepler Robotics describes the K2 (Bumblebee) as commercially available and in mass production, priced at about $34,000 (RMB 248,000) per unit per the company's official announcement. Most volume is sold through enterprise framework agreements rather than individual retail. The price is verified from Kepler's own release.
