Fourier N1 vs Unitree R1
Generated from the registry · revision 2026-09-26 · openness out of 100
Fourier N1 is 7 cm taller (130 vs 123 cm) and 9 kg heavier (38 vs 29 kg) than Unitree R1. Fourier N1 has 3 fewer degrees of freedom (23 vs 26) than Unitree R1. Openness score: Fourier N1 85, Unitree R1 30 (of 100); only Fourier N1 publishes CAD, BOM and POL. Availability for both: buy.
