52 humanoidsFourier N1 is 79 cm taller (130 vs 51 cm) and 34.5 kg heavier (38 vs 3.5 kg) than ROBOTIS OP3. Fourier N1 has 3 more degrees of freedom (23 vs 20) than ROBOTIS OP3. Openness score: Fourier N1 85, ROBOTIS OP3 45 (of 100); only Fourier N1 publishes CAD, BOM and POL; only ROBOTIS OP3 publishes FW. Availability for both: buy.
