Fourier N1 vs Unitree G1
Generated from the registry · revision 2026-09-26 · openness out of 100
Fourier N1 is 2 cm shorter (130 vs 132 cm) and 3 kg heavier (38 vs 35 kg) than Unitree G1. Both list the same degrees of freedom (23). Openness score: Fourier N1 85, Unitree G1 40 (of 100); only Fourier N1 publishes CAD and BOM. Availability for both: buy.
