The Fourier GR-2 is an upgraded humanoid robot standing 175 cm tall and weighing 63 kg with approximately 2 hours of battery life. It features 53 joints powered by seven types of FSA 2.0 actuators delivering up to 380 N·m peak torque with a dual-encoder system that doubles control accuracy. The robot walks at 5 km/h and is equipped with 12-DOF dexterous hands featuring six array-type tactile sensors for real-time force sensing, object shape and material identification, and adaptive grip adjustment. Integrated cabling for power and communication enables concealed wires and compact packaging. The Fourier Toolkit SDK provides pre-optimized modules via intuitive APIs and supports NVIDIA Isaac Lab, ROS, and Mujoco. It targets research, industrial, and generalist applications.
