Fourier GR-1 is the world's first mass-produced humanoid robot, marking a historic milestone for the industry when it entered production in 2023. Standing 165 cm tall and weighing 55 kg with 40 degrees of freedom, the GR-1 was designed with a unique focus on healthcare, caregiving, and physical therapy, an extension of Fourier's decade-long expertise in rehabilitation exoskeletons. Its Fourier Smart Actuator (FSA) system integrates motor, driver, reducer, and encoder into compact modules, enabling powerful and precise movements. The GR-1 supports a top walking speed of ~5 km/h and is capable of carrying loads of up to 50 kg, nearly its own weight, making it one of the strongest humanoids relative to body mass. A six-camera BEV vision system with Transformer-based occupancy networks enables advanced environmental perception and navigation.
