Fourier GR-2

Fourier's 2024 full-size humanoid robot, with 53 degrees of freedom and 12-DOF dexterous hands.

Fourier GR-2 is a full-size humanoid robot that Shanghai-based Fourier released in late September 2024, an upgrade to its earlier GR-1. Published specs: 175 cm tall, 63 kg, with 53 degrees of freedom (independently driven joints) across the body, including 12 in each dexterous hand; a single-arm payload of 3 kg; and a removable battery good for about 2 hours. The joints use Fourier's own FSA actuators, rated above 380 N·m of peak torque. GR-2 is sold mainly to universities and R&D teams for experiments such as teleoperation data collection and training manipulation policies; Fourier also released a companion software development platform alongside it.

ExampleA research team teleoperates GR-2's hands via VR to record grasping demonstrations, then uses that data to train an imitation-learning policy.
