Fourier has introduced GR-3, its first full-sized humanoid robot explicitly developed for care-related scenarios. The launch marks the latest addition to Fourier’s GRx humanoid series and signals the company’s entry into the emerging category of “Care-bots,” a designation for robots intended to provide emotional and physical support in human-centered environments.
GR-3 integrates Fourier’s proprietary Full-Perception Multimodal Interaction System, which combines vision, audio, and tactile sensing to process real-time emotional and contextual data. The robot is equipped with a four-microphone array for omnidirectional audio capture and localization, facial recognition through RGB and structured-light camera systems, and 31 pressure sensors for touch responsiveness. These features enable GR-3 to deliver context-sensitive, humanlike responses, supported by a dual-path system that balances rule-based reactions with language model-driven interaction.
The robot measures 165 centimeters in height and weighs 71 kilograms. It offers 55 degrees of freedom and incorporates modular architecture with high-performance actuators and 12-degree-of-freedom dexterous hands. The company states that GR-3’s mobility system allows it to perform a range of actions including walking, squatting, and navigating complex environments. A hot-swappable battery and intelligent power management system are included for continuous operation.
According to Fourier, GR-3 is intended for deployment in various real-world contexts, including public service, clinical care, academic research, and eventually, personal use. Its design includes a soft outer shell, cushioned surfaces, and a neutral aesthetic intended to make it more approachable for users across age groups and settings.
GR-3 also functions as a development platform. Fourier plans to provide APIs and a client-server architecture that supports algorithm integration and third-party application development. This infrastructure is aimed at enabling researchers and automation developers to adapt the robot for customized tasks and environments.
