What Fourier does

Fourier (legally Shanghai Fourier Intelligent Technology Co., Ltd.) is a Shanghai-based full-stack robotics company operating through three integrated product lines: humanoid robots (the GRx series — GR-1, GR-2, GR-3, and N1), a rehabilitation product family (RehabHub platform, MetaMotus Galileo biomechanical analysis, plus a suite of limb-specific devices including ArmMotus, WristMotus, ExoMotus, AnkleMotus, CycleMotus, AirFortis, OTParvos, and EXOPS), and proprietary components (the FSA actuator and the FDH6 dexterous hand). Core technology combines multimodal perception (visual, audio, tactile with 31 pressure sensors), a hybrid decision architecture fusing reflexive control with advanced language model reasoning, and open-source reinforcement learning training pipelines (Wiki-GRx-Mujoco on NVIDIA Isaac Gym). All products ship with Python and C++ SDKs (UDP on Linux) and detailed documentation at support.fftai.com.

The company generates revenue through hardware sales (humanoid robots, rehabilitation equipment, and standalone components), SDK and software licensing, and integrated "Smart Rehabilitation Port" turnkey solutions for healthcare facilities. Go-to-market is direct enterprise sales supplemented by channel distribution — notably the Rymo Technologies ASEAN partnership (FDA Class II) and direct collaborations with named institutional customers including Malaysia's National Social Insurance Agency Rehabilitation Center, University Malaya Medical Centre, China Construction Bank, SAIC-GM, and a network of academic research partners (ETH Zurich, CMU, Tsinghua, UT Austin, SFU). Fourier is recognized as one of China's "Humanoid Robot Big 5" alongside Unitree, Agibot, Leju, and Huawei, and has physical presence in Shanghai (HQ), Singapore (Marina One West Tower), and Kuala Lumpur (Menara Pernas). Pricing is quote-based and not publicly disclosed; the company made its US market debut at CES 2026 in Las Vegas.

Core offering

Fourier designs, manufactures, and sells full-stack robotics technology including the GRx series humanoid robots (GR-1, GR-2, GR-3, N1), a comprehensive rehabilitation robotics line (RehabHub, MetaMotus Galileo, ArmMotus, ExoMotus, and other limb/ankle/wrist devices), and proprietary components (FSA actuators and FDH6 dexterous hands) with Python/C++ SDKs. Offerings target enterprise customers across healthcare rehabilitation, industrial automation, commercial services, and academic research, with quote-based pricing and multi-year deployment contracts.

Product overview

Fourier Intelligence is a proactive AI company specializing in full-stack robotics technology to enrich people's lives. Its product portfolio spans humanoid robots (the GRx series — GR-1, GR-2, GR-3, and N1), rehabilitation robotics (RehabHub platform, MetaMotus Galileo, ArmMotus, WristMotus, ExoMotus, AnkleMotus, PelmaMotus, CycleMotus, AirFortis, OTParvos, EXOPS), and core components (Fourier Actuator FSA, Fourier Dexterous Hand FDH6). The GRx humanoid series serves as the core platform for human-centered applications including care, commercial services, research, and industrial automation, while the rehabilitation suite addresses physical therapy needs across hospitals and clinics. Component products (actuators, dexterous hands) support both Fourier's own robots and serve as standalone offerings with comprehensive Python/C++ SDKs. The company also maintains open-source simulation tools (Wiki-GRx-Mujoco) and operates the Fourier Nexus ecosystem platform connecting its technology with business and academic partners globally.
