About 40% on China-origin collected today: the 2.5% MFN base, 25% Section 301 List 1, and the 12.5% Section 301 forced-labor duty effective 24 Jul 2026 with no expiry. It began the same morning the 10% Section 122 surcharge lapsed, so the total rose from about 37.5% rather than falling to 27.5%. Confirm the live rate before ordering.

What is in the crate

1 included|3 not included

Hands

Hands sold separatelypriced by quote

23 DOF without hands; grippers or hands are your own integration on this open-source build, so there is no maker-published hand price (priced by whatever third-party effector you source).

In the crate

Nothing by default: it is a design. Kits vary by builder

You still have to add

Assembly Support Warranty (unless a kit builder provides one)

Day oneNone until built.

Reality check

There is no product to unbox: this is a free design plus a parts list, so the real cost is the workshop, the sourcing, and the months of assembly it takes to get one walking.

Can you get one, and what will it cost?

A planning estimate with machine, freight, duty, and tax shown separately.

Yes, with work

Yes, with work: importable into United States.

US authorization: We found no public FCC ID for this model. Since 28 July 2026 a foreign-made robot can be sold into the US only under an FCC authorization from before that date, so ask the seller for its FCC ID, or its Supplier's Declaration of Conformity dated before 28 July 2026, before you pay. Every humanoid you can still buy in the US

Optional hands: request a price

Optional hands are excluded until a seller quotes them. Spare batteries and other accessories are excluded. Confirm compatibility and pricing with the seller.

Where to buy

Catalog checked 2026-10

Individuals and companies can inquire. Confirm the configuration, stock, and delivery with the seller.

Open-source self-build; assembled units via third-party shops on demand.

Price notes: The design is free: Fourier publishes a hardware resource package (design schematics, BOM, assembly manuals and basic operating software code) through a Baidu Netdisk link on its N1 page, with SDK documentation and example code on GitHub, and there is no fixed Fourier retail SKU. Assembled units are sold on demand by third parties: Robotopian lists the N1 at $40,000 on backorder (checked 3 Oct 2026; the VecRobot kit shop that also sold it is offline), alongside the GR-3C at $85,000 and the GR-3 at $100,000. Component cost is far lower if you self-build, so treat $40,000 as the price of not doing the assembly yourself.

The maker's shares

All makers

Fourier: Private: its shares do not trade on any exchange.

Reports conflict on venue: BlockBeats (24 Jul 2026, citing SCMP) says Fourier started a Hong Kong listing process with CITIC Securities, CICC and Morgan Stanley as sponsors (not confirmed by the company), while a 36Kr tracker (19 Aug 2026) says it completed share reform and targets the STAR Market. No application appears on HKEXnews as of 29 Oct 2026 and the shares do not trade anywhere.

Size to scale

Drawn next to a 1.80 m (5 ft 11 in) person. Every robot on the site uses this same reference, so you can trust the comparison at a glance.

N1: 130 cm / 4 ft 3 in, 38 kg

Footprint: 43 cm wide x 22 cm deep

What it does on day onewith zero programming

None until built. Once built: 3.5 m/s locomotion, 2h runtime, and FSA 2.0 actuators, a design Fourier claims is validated by 1,000+ km of outdoor testing.

Best for: Well-equipped labs and serious hackers who want a completely open humanoid to build and modify.

Documented uses

Robotics R&D

Fourier describes the open-source N1 as purpose-built for embodied AI research and publishes design schematics, BOM, assembly manuals and basic operating software code.

Fourier lists no price or store for the N1, so you build it from the published package or buy a third-party assembly, and it has no hands and Chinese-language SDK documentation.

Source reviewed 2026-10-05

Assessment from published documentation, not an independent performance test. Applies to the configuration described above.

What it takes to developskills, gear, and SDK access

Serious: mechanical assembly, electronics, firmware flashing, and RL training. For capable labs and hackers only.

SDK access: Open source per Fourier: a hardware resource package (design schematics, BOM, assembly manuals) and basic operating software code, plus a Python SDK with Chinese documentation and RL training guides on GitHub. Fourier says it plans to release further modules for whole-body control and multi-task coordination. The hardware package is a Baidu Netdisk download, not a GitHub repo.
