Open-platform humanoid for research + light industrial pilots

5'5" / 55kg humanoid with 40 DoF, walking at 5 km/h, 50kg arm payload. Comes with open SDK and ROS2 stack — aimed at university research, robotics startups, and early industrial pilots (rehabilitation, light assembly, public spaces). Fourier is based in Shanghai; ~100 units sold/year. Lower price + open SDK make it the practical bridge between research and commercial humanoid deployment.
