The Fourier GR-1 is the world's first mass-produced and commercially delivered bipedal humanoid robot. With a highly biomimetic torso design that mirrors the human body's major degrees of freedom, the GR-1 delivers stable locomotion and agile movement, making it an ideal platform for general-purpose artificial intelligence.

Standing 165 cm tall and weighing 55 kg, the GR-1 features a full-body 44-DOF kinematic structure powered by Fourier's proprietary FSA (Fourier Smart Actuator) — a highly integrated unit combining motor, driver, reducer, and encoder in one compact module. It walks at up to 5 km/h and achieves a maximum joint torque of 230 N·m.

The GR-1 supports seamless human-robot interaction through an array of sensors including a circular microphone array for voice recognition, an Intel RealSense depth camera, a built-in speaker, and a high-resolution display. It also integrates large language model (LLM) voice interfaces for autonomous conversational interaction.

As the first humanoid robot with end-to-end environmental perception, the GR-1 uses 6 RGB cameras for 360° surround vision, combined with BEV + Transformer + OCC technology to generate a comprehensive global environmental map. Fourier collaborates with over 20 leading universities and research institutions worldwide to deploy the GR-1 in applications spanning guided services, eldercare companionship, and scientific research.
