The Fourier GR-3 Series is Fourier's first humanoid robot line built around the "Care-bot" concept — designed with the philosophy of "Beyond Function, With Enduring Care." The series combines a full-sensory interaction system with anthropomorphic motion control, delivering both functional capability and genuine emotional connection for human-centered robotics.

The GR-3 Series comes in two variants: the GR-3 "Cat Head" — a warm, approachable design optimized for social companionship and emotional interaction — and the GR-3C "Astronaut," featuring a wraparound display head and reinforced shell in a sci-fi white finish for demanding operational environments.

Built on Fourier's accumulated technology from two previous generations, the GR-3 Series features a fully optimized body structure with self-developed integrated actuators, a dual hot-swap battery architecture for uninterrupted 24/7 operation, and support for multi-DOF dexterous hands. Anthropomorphic gait modes, full-body teleoperation, and an "NPC standby mode" enable natural, versatile human-robot interaction across diverse scenarios.

The GR-3 Series offers an open, developer-friendly platform supporting a server-client architecture for algorithm debugging, data collection, and model training — empowering researchers, automation engineers, and AI developers to rapidly build and deploy customized applications in fields such as guided tours, eldercare, scientific research, and industrial efficiency.
