Robot overview

The GR-3 represents a shift in philosophy for Fourier, prioritizing "Engineering Warmth" over industrial aesthetics. Standing 165 cm tall and weighing 71 kg, the robot features an innovative soft-shell design - utilising automotive-grade upholstery and eco-friendly foam - to make it approachable and safe for physical interaction in homes and clinics.

Unlike previous models, the GR-3 is a proactive AI agent. It doesn't just wait for commands; it uses its unified "Full-Perception" system to identify social cues, remember faces, and engage in natural, context-aware dialogue via its integrated Large Language Model (LLM). It is currently being deployed in nursing homes and premium service centers to act as a responsive companion and health monitor.

Clad in premium, soft-touch materials and powered by a multimodal emotional intelligence engine, the GR-3 is the primary enterprise solution for elder care, hospitality, and educational support.

Technical Breakthroughs

Multimodal Interaction System: A real-time emotional processing engine that synchronizes 31 distributed pressure sensors, a four-microphone array, and RGB+Structured-light cameras. This allows the GR-3 to respond to a "hug," localise a voice in a crowded room, and maintain eye contact during conversation.
Animated Facial Interface: Beyond a static screen, the GR-3 features an expressive LED face and "character-rich" locomotion. It can tilt its head lovingly, blink, and display micro-expressions (happiness, concern, or curiosity) to foster user trust.
Dual-Path Cognitive Architecture: The robot uses a "Fast vs. Slow" thinking model. A rule-based controller handles rapid reflexive actions (like balancing or turning toward a sound), while a high-level LLM manages deep situational reasoning and situational dialogue.
Specialised "Soft-Touch" Hardware: Every joint is covered by a cushioned exterior that maintains industrial-grade durability while providing a tactile "friendliness." Its 12-DoF dexterous hands are optimized for safe, light-duty interaction, such as handing a patient a drink or playing a game of chess.

Deployment

+ Scalability

CES 2026 Global Debut: Fourier officially brought the GR-3 to the international stage at CES 2026, demonstrating its readiness for the U.S. and European healthcare markets.
The "Care-bot" Ecosystem: Deployment is focused on Smart Eldercare and RehabHub™ facilities. By early 2026, the GR-3 has already been integrated into clinical settings for health monitoring and physical rehabilitation assistance.
Miniature Scaling (The "Baby" Version): To increase market penetration, Fourier introduced a "doll-sized" version of the GR-3 at CES 2026. This smaller, affordable unit uses the same AI stack for home companionship where a full-sized humanoid isn't required.
24/7 Service Readiness: Like its industrial siblings, the GR-3 features a hot-swappable battery system (3-hour avg. runtime). This ensures that in a hospital or hospitality setting, the robot never has to "sleep," providing around-the-clock emotional and physical support.
