When to pick which
Choose the Fourier Intelligence GR-1 for industrial R&D or logistics pilot programs where physical capability is paramount. With a 50kg payload capacity—significantly higher than the GR-3—it is the superior choice for light manufacturing tasks like material handling or collaborative assembly testing. University laboratories focused on gait dynamics or teleoperation will benefit from its 1.4m/s speed and open-platform SDKs including ROS2 and Python, allowing for deep hardware-level control. Select this model if your deployment requires a robust mechanical worker capable of lifting substantial weights or operating in environments where rapid movement and open-source integration are critical for experimental success.
Select the Fourier Intelligence Fourier Intelligence GR-3 for service-oriented deployments in healthcare, assisted living, or public hospitality where human-robot interaction is the primary goal. Despite its lower 3kg payload, its 55 degrees of freedom allow for more nuanced, expressive movements essential for emotional connection and social companionship. The dual hot-swappable batteries and 3-hour runtime make it better suited for continuous shifts in high-traffic public spaces or clinics. Choose this model for academic research into social robotics or service assistant roles where dexterity and uptime outweigh raw lifting power, especially when leveraging the LeRobotDatasetV2 pipeline for behavioral training.
