Fourier

Fourier started in 2015 as a maker of rehabilitation robots and exoskeletons for hospitals. It now builds the GRx humanoid line: GR-1 (2023), GR-2 (2024), the care-focused GR-3 series (2025), the open-source N1 research robot (2025) and the GRW wheeled dual-arm robots (2026). It also makes rehabilitation systems (RehabHub, Galileo) and the GR Nano, a 200 g plush desktop companion that is not a humanoid. Omdia estimated it shipped 300 humanoids in 2025, sixth in the world. In 2026 it co-built Meta's 'Max' humanoid prototype.

ModelStatusAnnouncedHeightWeightDoFPayloadRuntimePrice
GRW wheeled ↗First high-payload wheeled dual-arm robot, unveiled at WAIC 2026. Four-wheel-drive base. Height 1231–1695 mm; average speed ≈0.8 m/s; rated dual-arm payload 16 kg; hot-swappable batteries. The Oct 2026 catalog gives weight ≈240 kg, but the launch report gave ≈160 kg and 29 DoF excluding end effectors (Science and Technology Daily). Commercial2026-07 —240 kg —16 kg 4 h not published
GR-3 ↗'Care-bot' for companionship and interaction: 31 pressure sensors, four-mic array, hot-swappable batteries. 43 DoF in the standard build with 6-DoF hands; up to 55 DoF with the optional 12-DoF hands (support doc). Catalog figures: height ≈165 cm, weight ≈71 kg, single-arm payload ≈3 kg, runtime ≈3 h. Speed 6.1 km/h is from the support doc. Commercial2025-08 165 cm71 kg 433 kg 3 h not published
N1 ↗First open-source humanoid: full bill of materials, blueprints, assembly guides and control code released. Runtime is 'over two hours' per charge; running speed up to 3.5 m/s. Commercial2025-04 130 cm38 kg —— 2 h not published ('pricing remains flexible', per Fourier's R&D director)
GR-2 ↗Second generation: 12-DoF hands with six array tactile sensors, swappable battery, FSA 2.0 actuators. The 5 km/h walking speed is from the support doc. The June 2025 Runyang filing says GR-1 and GR-2 are in volume production. GR-2 is not in the Oct 2026 catalog. Commercial2024-09 175 cm63 kg 533 kg 2 h not published
GR-1 ↗First generation, unveiled at WAIC 2023. Fourier's own FSA actuators; hip joint peak torque 300 Nm; source says it can 'carry objects of 50 kg'. Fourier calls it 'the first mass-produced humanoid robot in the industry'. Not in the Oct 2026 catalog. Commercial2023-07 165 cm55 kg 4050 kg — not published
GR-3C / GR-3C Ultra ↗Variants of GR-3 for practical tasks, with a matte hard shell. The Ultra adds LiDAR for real-time obstacle avoidance. Same specs as GR-3, all '≈' in the catalog. Commercial— 165 cm71 kg 433 kg 3 h not published
GRW Lite wheeled ↗Lighter wheeled dual-arm robot running on NVIDIA Jetson Thor. Height 1307–1907 mm; rated dual-arm payload 3 kg; average speed ≈0.8 m/s. Commercial— —120 kg —3 kg 4 h not published
