52 humanoidsBooster K1 is 35 cm shorter (95 vs 130 cm) and 18.5 kg lighter (19.5 vs 38 kg) than Fourier N1. Booster K1 has 1 fewer degrees of freedom (22 vs 23) than Fourier N1. Openness score: Booster K1 30, Fourier N1 85 (of 100); only Fourier N1 publishes CAD, BOM and POL. Availability for both: buy.
