Overview

Fourier, originally a rehabilitation-robotics company, unveiled GR-1 at WAIC in July 2023 as one of the first Chinese full-size humanoids offered for sale. GR-2 (September 2024) increased height and DoF and added 12-DoF tactile hands. Fourier still lists both on its GRx page (GR-2 brochure updated May 2025), though the GR-3 care-bot and N1 open platform are now its newer models.
