Summary:

 

The GR-1 is a general-purpose humanoid robot developed by Fourier Intelligence, a Shanghai-based robotics company. Standing 165 cm tall and weighing 55 kg, GR-1 features up to 54 degrees of freedom, a walking speed of 5 km/h, and the ability to lift nearly its own weight. It is one of the first humanoid robots to enter mass production, with applications in rehabilitation, logistics, and AI research.

 

Editorial:

 

GR-1 represents a major milestone in humanoid robotics: a mass-producible, human-sized robot with real-world utility. Its Fourier Smart Actuators (FSA) integrate motor, driver, reducer, and encoder into compact modules, enabling smooth, coordinated movement across the body. The robot is capable of twisting, squatting, gripping, and navigating obstacles, making it suitable for both structured and semi-structured environments.

 

Powered by large language models (LLMs) and equipped with vision and sound sensors, GR-1 supports natural human-robot interaction. It’s designed to assist with physical tasks, provide companionship, and serve as a research platform for embodied AI. Fourier Intelligence has positioned GR-1 as a scalable solution for aging societies, rehabilitation centers, and smart service environments.
