Summary
The Fourier GR-1, in production from late 2023, was marketed as the world's first mass-produced humanoid. It is a 165 cm, 55 kg bipedal robot with 40 degrees of freedom and 11-DOF dexterous hands, reflecting Fourier's rehabilitation-robotics heritage.
GR-1 delivers up to 300 N·m of peak joint torque, walks at around 5 km/h and is marketed with a 50 kg carry-capacity claim that should be treated as a manufacturer figure rather than an independently verified payload. It ships with the GRx development platform and supports ROS and NVIDIA Isaac, plus teleoperation and lead-through programming for research and enterprise users. As Fourier's first humanoid it laid the groundwork for the more capable GR-2 and the healthcare-focused GR-3 'Care-Bot'. Fourier's rehabilitation division gives the GR line an unusual route into medical and research institutions worldwide.
