Company Claim
Fourier's own GR-2 product page names ETH Zurich, Carnegie Mellon University, Simon Fraser University, and Tsinghua University as research partners, and Fourier separately published a demonstration video of GR-2 performing tasks at an SAIC-GM automotive facility
What's Actually Confirmed
The four research partners are confirmed directly on Fourier's own page. The SAIC-GM appearance is a company-published demo video, not an independently confirmed production deployment — CnEVPost's March 2026 reporting on SAIC-GM's actual production-line humanoid identifies it as a wheeled robot built by AGIBOT, a different manufacturer, not Fourier's GR-2

How much does the GR-2 weigh?
GR-2 weighs 63 kg / 138.9 lb.
How much can the GR-2 carry?
GR-2 can carry a payload of 3 kg.
How much does the GR-2 cost? Is the GR-2 available to buy?
Fourier Robots has not published a price for the GR-2 — it is quoted on enquiry. No public pricing. Contact Fourier Robotics directly.
What are the main strengths of the GR-2?
- 53 DoF with 12 DoF per hand — high dexterity for a research platform
- FSA 2.0 actuators with 380 N·m peak torque and dual-encoder precision
- Hot-swappable battery for reduced downtime
- Broad simulation compatibility — Isaac Lab, ROS, MuJoCo
- Established research deployments at top-tier institutions
What are the limitations of the GR-2?
- 3 kg single-arm payload limits industrial task applicability
- No public pricing — purchase process opaque
- 2-hour battery runtime is short for extended experiments
- No independently verified autonomous task benchmarks published
- No confirmed industrial/production deployment — the widely-circulated 'SAIC-GM deployment' claim is a demo video, not a production relationship
