Overview
Fourier Intelligence GR-2 is a Shanghai-based humanoid robot that stands out for one remarkable specification: 53 total degrees of freedom, including 12 DOF per hand — more than any competing platform. Built on the OpenLoong open-source stack, GR-2 offers full ROS2 integration and a growing research community. Fourier Intelligence brings a background in rehabilitation robotics (exoskeletons), which shows in the biomechanically accurate joint designs and force/torque sensor integration. At ~

Pros & Cons
Strengths
- 53 total degrees of freedom including 12 DOF per hand — best dexterity in research robotics
- OpenLoong open-source software stack — full ROS2 ecosystem with active community
- Intel RealSense depth cameras and 6-axis force/torque sensors throughout
- Best-in-class hand dexterity (12 DOF/hand) for the price tier
- Strong academic credentials with rehabilitation robotics background (exoskeletons)
Weaknesses
- Battery life of ~1 hour is the shortest of any humanoid in this class
- Low hand payload (3 kg) despite high DOF count
- Smaller international support network compared to US and top-tier Chinese competitors
- Walking speed comparable to competitors but terrain adaptability lags Atlas-class robots
