Fourier GR-2

Fourier

GR-2 is the second-generation general-purpose humanoid independently developed by Fourier, building on the data and technology accumulated with GR-1 to achieve comprehensive breakthroughs in hardware design, framework development and commercialisation. Whole-body degrees of freedom reach up to 53 (with an optional enhanced 12-DOF dexterous hand), maximum joint peak torque is 436 N·m, walking speed 5 km/h, single-hand load about 3 kg, and standard runtime about 2 hours with a removable battery-swap design. The dexterous hand has up to 12 degrees of freedom per hand with six array tactile sensors supporting force-controlled grasping; the platform supports NVIDIA Isaac Lab, ROS, MuJoCo, Webots and other open-source frameworks, offering more dexterous upper-body manipulation, a stronger power system and a more open development platform.
