GR-3

Overview

GR-3 is Fourier Robotics' first humanoid designed explicitly for social and emotional interaction rather than industrial or research tasks. Launched as part of the GR-3 Series in October 2025, it features 31 distributed pressure sensors across the body, expressive eye displays, and a dual-path AI architecture. A commercially oriented variant, the GR-3C, adds a reinforced shell and full-body teleoperation support.

GR-3 stands 165 cm tall and weighs 71 kg with 55 degrees of freedom across the whole body, per Fourier's official documentation. Single-hand load capacity is 3 kg. Each arm has 7 degrees of freedom across shoulder, elbow, and wrist joints; each leg has 6 degrees of freedom. The head has 2 degrees of freedom and integrates a monocular camera, two eye display screens, a four-microphone array with omnidirectional voice activation and echo cancellation, and an RGB plus structured-light camera module for facial recognition and dynamic tracking.

GR-3 is Fourier's first robot designed explicitly for social and emotional interaction rather than industrial or research tasks — the company describes it as a care robot. The full-sense interaction system integrates vision, audio, and touch into a unified real-time processing engine. Thirty-one distributed pressure sensors across the body enable touch detection; the robot responds to contact with animated micro-expressions. A dual-path response architecture handles both rapid reflexive actions via rule-based control and contextual dialogue via a large language model.

GR-3 is part of Fourier's GR-3 Series, which also includes the GR-3C — a commercially oriented configuration with a reinforced aluminium and engineering-plastic shell, an LED ring-screen head, and optional 12-DoF dexterous hands. GR-3C supports full-body teleoperation and real-time remote motion mapping. Both variants use dual hot-swappable batteries, rated at 3 hours runtime per Fourier's official product page. Fourier published the GR-3 Series brochure in October 2025. No public pricing is listed for either GR-3 or GR-3C; contact Fourier directly.
