Fourier Robotics :: Advanced Humanoid & Embodied AI Robots

Fourier Robotics (also known as Fourier Intelligence) is a Shanghai-based general-purpose robotics company founded in 2015. Originally focused on rehabilitation robotics and exoskeletons, the company has evolved into a full-stack developer of advanced humanoid and embodied AI robots. Fourier’s mission is to leverage cutting-edge robotics technology to enrich human lives, with products spanning healthcare, scientific research, industrial applications, and everyday companionship. The company emphasizes practical deployment, accessibility, and integration with large AI models, positioning itself as a bridge between research and real-world robotics. Fourier has gained international recognition, with its robots used by leading research institutions and commercial partners across more than 40 countries.

Fourier’s humanoid robot series, known as the GRx lineup, represents its flagship offerings in general-purpose robotics.

Key Robot-Based Products:

• GR-1: Fourier’s first mass-produced humanoid robot. Standing approximately 165–175 cm tall with around 40–50 degrees of freedom, it was designed for practical applications in healthcare, research, and service roles. It demonstrated reliable bipedal walking and basic manipulation capabilities.
• GR-2: An upgraded model released in 2024. It features improved hardware (175 cm height, 63 kg weight, 53 degrees of freedom), better dexterity (12-DoF hands), enhanced motion control, and greater agility. It is positioned as a more capable platform for complex tasks and developer use.
• GR-3 Series: The latest generation, including variants like GR-3 Kitty. It features a softer, more approachable design with premium upholstery and foam padding. GR-3 emphasizes emotional interaction through multimodal sensing, natural gestures, and a caring personality. It is optimized for companionship, assistance, and human-centric applications, with strong focus on safety and emotional intelligence.

Fourier also maintains a strong rehabilitation robotics portfolio, including exoskeletons and the RehabHub™ platform, which integrates robotics with VR for physical therapy. The company provides open platforms, developer tools, and data ecosystems to support broader embodied AI research and commercialization. Its robots are known for balancing performance, cost-effectiveness, and real-world usability, with continuous improvements in hardware, software, and AI integration. Fourier continues to expand its GRx series and ecosystem to accelerate the adoption of humanoid robots in everyday life and industry.
