How to read the status badges
- Confirmed Read on the maker's own page, spec sheet, docs or press release as a stated value.
- Claimed Stated by the maker as a target, preliminary figure, “up to” value or performance claim.
- Estimated Derived by us or taken from a third party. Not maker data.
- Unverified No maker primary source checked yet. Treat as unconfirmed.
- Not published The maker does not publish this value.
Every Confirmed, Claimed or Estimated value links to its source and shows the date it was checked.
ZeroGantry verdict: 4 out of 5
Fourier GR2 is the dark horse of the humanoid market — less hyped than Figure or Optimus, but with the best force-control architecture of any robot in its price class. The 40-DoF dual-arm system with 8-DoF dexterous hands is unmatched for bimanual manipulation tasks, and the 0.1N torque resolution enables true compliant control that makes the robot safe to operate alongside humans without cages. The open SDK is a breath of fresh air in a market dominated by closed ecosystems — researchers and integrators can actually build on this platform. The weakness is deployment maturity: while Fourier has pilots in rehab and light assembly, there's no BMW Spartanburg or GXO Logistics-scale deployment to point to. The 2-hour battery and slow walking speed also constrain it to stationary or near-stationary work cells. For research labs and early-stage commercial pilots needing dexterous dual-arm manipulation with an open SDK, GR2 is the best value proposition available.
