Commercial record

What it actually costs.

Pricing is presented in full, not flattened to one number. Figures vary by configuration and by where the unit is purchased.

Pricing

Not publicly priced

Fourier does not publish pricing for the GR-2; sales are institutional and enterprise, handled directly through Fourier. One third-party estimate places the unit cost above $150,000, but it is an estimate, not a published price.[5]

Overview

The GR-2 is Fourier's second-generation general-purpose humanoid, unveiled September 30, 2024 as the successor to the GR-1 and carrying the company's rehabilitation-robotics lineage. At 175 cm and 63 kg with 53 degrees of freedom, it moves to a serial joint architecture (redesigned from the GR-1's parallel arrangement) built on FSA 2.0 actuators, and adds 12-DoF dexterous hands with array-type tactile sensing and a detachable, swappable battery with twice the GR-1's capacity. Units are deployed to research institutions including ETH Zurich and Carnegie Mellon University. Fourier subsequently unveiled the GR-3 Care-Bot in August 2025; the GR-3 is not yet catalogued in this index.

Strengths

  • 53 degrees of freedom with 12-DoF dexterous hands carrying array-type tactile sensors.
  • FSA 2.0 actuation with peak joint torque of 380 N·m across seven actuator types.
  • Serial joint architecture, redesigned from the GR-1's parallel arrangement.
  • Detachable, swappable battery with twice the GR-1's capacity.
  • Deployed to research institutions including ETH Zurich and Carnegie Mellon University.

Considerations

  • Overall lifting capacity is not announced by Fourier; only the approximately 3 kg per-arm payload is reported.
  • No manufacturer pricing exists; the above-$150,000 figure is a third-party estimate, and sales are institutional and enterprise only.[5]
