Fourier N1 - Fourier's first open-source humanoid robot

What is Fourier N1?

Fourier N1 is the first open-source humanoid robot released by Fourier Robotics. Standing 1.3 meters tall and weighing 38 kilograms, it boasts 23 degrees of freedom and utilizes a composite structure of aluminum alloy and engineering plastics, combining strength and flexibility. Equipped with the FSA 2.0 integrated actuator and a self-developed control system, it achieves a maximum stable running speed of 3.5 meters per second and is capable of performing complex maneuvers such as standing on one leg and pushing off the ground to climb. Its removable battery design on the back provides over 2 hours of continuous use, meeting the needs of high-frequency testing and convenient deployment.

Main functions of Fourier N1

• Motion control functionWith 23 degrees of freedom, it can simulate various human movements and perform challenging actions such as traversing slopes with an incline of 15° to 20°, climbing stairs with a height of 20 cm, standing on one leg, and pushing off the ground to get up. It demonstrates excellent reliability and robustness of movement in unstructured scenarios.
• Multimodal interaction functionIt possesses multimodal interaction capabilities, and can effectively understand and respond to various input methods such as voice, vision, and touch, greatly enhancing the naturalness and fluency of human-computer interaction.
• Open source sharing functionalitySimultaneously, a complete ontology resource package, including bill of materials, design drawings, assembly guides, and basic operating software, will be released. In the future, inference code and training frameworks for this platform will be gradually released to provide a more complete verification and development environment for global developers.

The technical principle of Fourier N1

• High degree of freedom designThe Fourier N1 has 23 degrees of freedom, which can simulate the complex movements of the human body, and exhibits a high degree of flexibility and adaptability during movement.
• Self-developed power systemEquipped with Fourier's self-developed FSA 2.0 integrated actuator, combined with a self-developed control system, it enhances motion stability and impact resistance, achieving higher precision posture control. The highest measured stable running speed reaches 3.5 meters per second, demonstrating excellent dynamic response capabilities.
• Motion Algorithm ValidationDuring the R&D phase, Fourier N1 underwent extensive and intensive motion algorithm verification. The core control system met the expected technical standards in key performance aspects such as response speed, precision control, and anti-interference capabilities. In the engineering verification phase, N1 has accumulated over 1000 hours of outdoor complex terrain testing, with a single continuous operation time exceeding 72 hours, comprehensively verifying the stability, durability, and environmental adaptability of its structural design. Simultaneously, N1 can stably perform challenging maneuvers such as traversing slopes with gradients of 15°–20°, climbing stairs with a height of 20 cm, standing on one leg, and pushing off the ground to rise, demonstrating excellent reliability and robustness in unstructured environments.
