The Fourier GR-1 is described as the first mass-produced humanoid robot, standing 165 cm tall and weighing 55 kg. It features 44 joints powered by the Fourier Smart Actuator (FSA), which integrates motor, driver, reducer, and encoder into a single module, delivering up to 230 N·m peak torque and 5 km/h walking speed. A pure vision perception solution combines BEV, Transformer, and Occupancy Network with six RGB cameras to generate a real-time 3D occupancy grid. It supports LLM-powered human-robot conversation with built-in emotional systems and high-resolution displays, plus a ring-shaped microphone and RealSense camera. It targets generalist, research, and reception applications including concierge, guide, and assistant roles.
