Fourier N1
N1 is Fourier's open-source humanoid: the company published the bill of materials, CAD files, actuator specs and training code. It is 130 cm tall and aimed at developers and universities.
The verdict
Fourier's research platform, available through distributors at around $40,000. It sits between the G1 EDU and the full-size machines, and Fourier's medical rehabilitation background shows in the actuator quality.
- Buy it if
- Research groups that want a supported full-size platform from an established maker.
- Skip it if
- You can do the work on a G1 for a quarter of the price.
In its favour
- Solid actuators
- Distributor availability
- Established company
Against it
- Around $40,000
- Smaller community than Unitree
- No North American retail channel
How the score is built
Capability is what the machine physically does. Value compares it with others at a similar price, not with the whole market. Buyability asks whether you can really order one. Ecosystem is the software and community around it. Proof is what it has done in the field, which is where most humanoids score badly and should.
Similar money, different machine.

Index position
In the Humanoid Index, which ranks on shipped reality rather than value for money, Fourier N1 sits at #10 of 107 with 52 points: deployment 14/50, autonomy 18/30, availability 20/20. See that method.
Deposits, lead times and warranties: reading a humanoid order sheet
Of 42 buy records, 2 publish a deposit, 1 a warranty, 1 a shipping cost and none a lead time in weeks. The order sheet for a humanoid is mostly blank, and the blanks are where the money goes.
How long does a humanoid robot actually run
22 of 182 humanoids on record quote a runtime. The claims run from 1 to 8 hours with a median of 4, and of the 44 machines you can order, 4 say anything at all.
Open-source humanoids: what you can actually build
24 of the 182 humanoids on record call themselves open source. 15 publish hardware files and software, 3 name a licence, 12 can be ordered, and none of the four on preorder has any autonomy evidence yet.
Other robots by Fourier.
Fourier GR-1
GR-1 was revealed at WAIC in July 2023 and entered production the same year, one of the first Chinese humanoids sold in volume to research labs. It grew out of Fourier's rehabilitation robotics business.
Fourier GR-2
GR-2 doubled the battery capacity of GR-1 with a swappable pack and added 12-DOF hands, for a total of 53 degrees of freedom. The payload figure refers to each arm.
Fourier GR-3
GR-3 is Fourier's care-oriented humanoid with a soft, sensor-covered exterior and a rounded design meant for elder care and rehabilitation. It marks Fourier's move from research platforms to healthcare products.
