Fourier GR-1 is the second most accessible full-scale humanoid — direct purchase, ROS support, and 30+ research institution deployments, built on Fourier's medical rehabilitation actuator expertise.
Who is it for?
- Research labs wanting a full-scale humanoid with direct purchase access and ROS support
- Universities studying bipedal locomotion and whole-body manipulation
- Institutions comparing GR-1 with Unitree H1 for research programs
Key specs
- Height: 165 cm
- Weight: 55 kg
- Speed: 5 km/h
- DOF: 44 total
- SDK: ROS; Python; open-source community
- Deployments: 30+ research institutions

How it compares
GR-1 vs Unitree G1: GR-1 is larger (165cm vs 127cm) and more expensive, but has more DOF and Fourier's actuator quality. G1 is cheaper and has a bigger community. GR-1 is better for research needing full-scale.
Limitations
- Chinese origin — not NDAA compliant
- Less developer community than Unitree
- Full-scale humanoid requires safety infrastructure
- Fourier primarily known for rehab — humanoid brand still building
FAQ
How much does the Fourier GR-1 cost?
The Fourier GR-1 is priced between $55,000 and $90,000 and is available for direct purchase at fftai.com — making it the second most affordable directly purchasable full-scale humanoid robot globally, after the Unitree G1 at $16,000.
What is the Fourier GR-1 used for?
The GR-1 is primarily used in academic research — deployed at over 30 institutions globally for bipedal locomotion studies, whole-body manipulation research, and humanoid AI experiments. Its ROS support, open SDK, and direct purchase availability make it the most accessible full-scale humanoid for university research programmes.
What are the key specs of the Fourier GR-1?
The GR-1 stands 165 cm tall, weighs 55 kg, and walks at up to 5 km/h. It has 44 degrees of freedom across its entire body, supports ROS and Python development, and is manufactured by Fourier Intelligence — a company known for its medical rehabilitation exoskeleton actuator technology.
Who is the Fourier GR-1 designed for?
The GR-1 targets university research labs and institutions wanting a directly purchasable full-scale humanoid with strong ROS support. Fourier's rehabilitation robotics background gives GR-1 actuator quality that researchers value for precise, compliant joint motion — particularly relevant for human-robot interaction and manipulation studies.
How does the Fourier GR-1 compare to the Unitree G1?
The GR-1 is larger (165 cm vs 127 cm), heavier (55 kg vs 35 kg), more expensive ($55K–90K vs $16K), and has more total DOF (44 vs 43) than the Unitree G1. GR-1 is better for research requiring full human-scale interaction and has medical-grade actuator heritage; G1 is more affordable with a significantly larger global developer community.
