Why it matters
One of the first Chinese humanoids pitched for mass production, from a company that started in rehabilitation robots.
Real-world use
Small batches delivered to universities and AI firms in 2023; Fourier aimed at about 100 units by end of 2023.

- Hands
- unknown
- Movement
- Walks on legs · 40 joints
- Actuators & motors
- 40 degrees of freedom; Fourier's own joint modules with a hip module peaking at 300 Nm (press). Fourier pitched electric joints as cheaper to mass-produce than hydraulics.
- Other details
- Walks 5 km/h and carries a 50 kg load (company claims at launch). Battery, sensors and compute not published in sources found.

Side by side with its peers
Picked by the same rules for every humanoid: another maker’s robot that moves the same way, is at the same stage and does at least one of the same main jobs, first shown within two years. Closer size and price rank higher. Few robots match closely, so these are the nearest matches. How we choose
