Fourier Unveils GR-1's Breakthrough in Vision Technology for Enhanced Environmental Perception

Seattle, WA, USA, June 19, 2024 - Fourier, the leading general-purposed robotic company announced a significant leap forward in perception technology for its humanoid robot GR-1 by integrating a camera-based pure vision solution that includes bird's eye view (BEV) , transformer models, and occupancy network. GR-1 is pioneering as the first humanoid robot to adopt this advanced visual perception solution.



Environmental perception is fundamental for humanoid robots transitioning from labs to real-world applications. It empowers robot to perceive the surroundings and make informed decisions through sensor data analysis.

In the newly adapted pure vision setup, Fourier positions 6 RGB cameras around GR-1, providing a complete 360-degree view. This configuration enables the robot to comprehensively sense the environment from all angles, including front, side, and rear views, and to generate BEV images for precise identification and tracking.



Based on BEV images, GR-1 employs transformer models to convert the complex environment into three-dimensional spatial features, enabling it to comprehend the environment's layout and assess occupancy possibilities. The occupancy network then translates data into a three-dimensionaloccupancy grid, helping GR-1 navigate passable and impassable areas.

During outdoor walking tests, GR-1 demonstrated high efficiency and accuracy in detecting vehicles and pedestrians along sidewalks. The test results underscored GR-1's capability for real-time object tracking and environmental mapping while in motion.



Fourier's camera-only approach reduces the system’s hardware costs while enhancing GR-1's environmental perception, achieving safer and more efficient operations with human-like precision. This allows GR-1 to excel in high-definition spatial positioning, extended-range visibility, and precise  object identification and differentiation.

“This advancement marks a new stage of our research in embodied AI,”said Roger Cai, director of robot application R&D of Fourier. “With our pure vision solution, GR-1 is poised to play a pivotal role in diverse applications such as medical rehabilitation, family services, reception and guidance, security inspection, emergency rescue, and industrial manufacturing.”
