Fourier Intelligence is a Chinese robotics company that has grown from a rehabilitation robotics specialist into a general-purpose humanoid and embodied-AI developer. Founded in 2015 and headquartered in Shanghai's Zhangjiang Hi-Tech Park, Fourier built its early reputation on robotic rehabilitation and exoskeleton systems before extending its expertise in actuation, control, and human-robot interaction into full humanoid robots. That clinical heritage informs an emphasis on safe, compliant interaction with people.
The company's flagship humanoid line is the GR series. The GR-2, its next-generation robot, stands about 175 cm tall and weighs roughly 63 kg, with 53 degrees of freedom and 12-degree-of-freedom dexterous hands equipped with tactile sensors. This combination of articulation and touch sensing is aimed at research and practical deployment in human-robot interaction, mobility, and manipulation tasks. Fourier designs the GR series as a modular platform for developers building embodied-AI applications.
Beyond hardware, Fourier invests in the software and training infrastructure needed to make humanoids useful. The company has worked with NVIDIA Isaac Gym to train its humanoid robots for real-world roles, reflecting a broader industry shift toward simulation-driven learning of locomotion and manipulation skills. Fourier has also expanded into humanoid care robots, applying emotional and interaction-focused AI that connects back to its rehabilitation origins.
Fourier secured nearly ¥800 million, about $109 million, in Series E funding announced in January 2025, with participation from Guoxin Investment, Pudong Venture Capital, Prosperity7, and others. The company, led by founder and CEO Gu Jie, plans to use the funding to advance its goal of building leading embodied-AI robots and to deepen its global R&D and manufacturing footprint as humanoid demand accelerates.
