Fourier N1

by Fourier Intelligence

Fourier N1 is an open-source compact humanoid from Fourier Intelligence, standing 1.3m and weighing 38kg yet running at up to 3.5m/s. Fourier publishes the full drawings and code, letting developers build and modify it for demanding moves from hill-climbing to single-leg balancing. With 23 degrees of freedom and 144N·m of peak torque, it's a hands-on developer platform.
