About Fourier Intelligence

Fourier Intelligence was founded in 2015 in Shanghai, China, and built its reputation on exoskeleton rehabilitation devices before pivoting to general-purpose humanoid robots. This medical background gives Fourier a unique advantage in biomechanically accurate joint design and force/torque sensing. The GR-2 humanoid features 53 total degrees of freedom — including 12 DOF per hand — among the most of any open-source research humanoid. The OpenLoong open-source software stack, contributed to by Shanghai's AI industry consortium, gives GR-2 one of the strongest developer ecosystems among Chinese humanoids. With Intel RealSense depth cameras, 6-axis force/torque sensors, and full ROS2 support, GR-2 is positioned as one of the most research-friendly premium humanoids, available through enterprise programs at around $150,000.
