Editorial summaries

Fourier GR-3

The GR-3 is the flagship full-size humanoid from Fourier Intelligence, a Chinese company rooted in medical and rehabilitation robotics, a focus distinct from the consumer-home cohort. There is no consumer product, price, or availability on record; the editorial position is honest-absence.

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.
