Gr 1

Overview

The Fourier Intelligence GR-1 was the first-generation GR humanoid from Fourier Intelligence, standing 1,650 mm, and has since been discontinued and replaced by the GR-2 and GR-3 lines. It was notable for being one of the first commercially available full-body humanoids from a Chinese manufacturer and for its open API, which enabled research integration and attracted a community of developers and researchers. The GR-1 played a significant role in demonstrating that a Chinese manufacturer could deliver a capable, research-ready bipedal humanoid to international buyers, establishing Fourier's reputation in Western research markets. Software support for the GR-1 is expected to wind down progressively as Fourier focuses resources on current-generation platforms.

Key Specifications

• Height: 1,650 mm
• Notable feature: open API for research integration
• Status: discontinued
• Price: not applicable; no new units available

Use Cases

The GR-1 was used in research and early pilot applications, particularly by university groups exploring whole-body control algorithms and dexterous manipulation. Its open API made it popular with researchers who needed to integrate the robot with custom learning frameworks and external AI systems. Fourier's healthcare background gave early buyers confidence in the hardware build quality.

Buying Used

Secondhand GR-1 units may appear through research institutions as labs transition to GR-2 or GR-3 platforms. Software update support from Fourier for the GR-1 should be confirmed before purchase, as continued support for a discontinued platform cannot be guaranteed long-term. Buyers purchasing GR-1 units for research purposes should be prepared to maintain and potentially fork the software stack independently, as the open API design makes this more feasible than on more closed platforms.

Alternatives to Consider

• Fourier GR-2 ($125,000): the current available generation with higher payload and continued manufacturer support
• Unitree H1 ($90,000): comparable specification with strong community support and international availability
• Unitree G1 ($16,000): much lower cost if budget is the primary constraint and research goals are compatible
