52 humanoidsFourier N1 is 30 cm shorter (130 vs 160 cm) and 22 kg lighter (38 vs 60 kg) than Adam Lite. Fourier N1 has 2 fewer degrees of freedom (23 vs 25) than Adam Lite. Openness score: Fourier N1 85, Adam Lite 20 (of 100); only Fourier N1 publishes CAD, BOM, SW and POL. Availability for both: buy.
