Fourier

A Shanghai humanoid robot company that started in rehabilitation robotics, maker of the GR series.

Fourier was founded in Shanghai in 2015 by Jie Gu, a graduate of Shanghai Jiao Tong University who had previously worked in sales management at National Instruments (NI); the company is named after the mathematician Fourier. It started out making rehabilitation robots and exoskeletons for hospital rehab departments, and began developing humanoid robots in 2019, using its own in-house FSA integrated actuators for the joints. It released the GR-1 in 2023, one of China's earlier humanoid platforms delivered at volume to universities and research institutions; the GR-2 followed in September 2024, then the GR-3, aimed at care and companionship settings, alongside the open-sourced real-robot dataset ActionNet. Investors include IDG Capital and Saudi Aramco, and reports say it closed a Series E of nearly RMB 800 million in early 2025. Its distinguishing feature is entering from rehabilitation medicine and pushing humanoid robots toward elder care and caregiving applications.

ExampleiDP3, the humanoid version of 3D Diffusion Policy, was validated on a real Fourier GR-1.
