Fourier GR-3 Series

A Caring and Capable Companion

GR-3 "Meow-bot"

GR-3 is Fourier's first full-size "Care-bot" designed for wellness companionship. Beyond functionality, it is
designed to foster emotional connection — introducing a new class of AI robots for human-centered scenarios.

Groundbreaking Concept Innovation

Beyond pure functionality, we add the element of companionship. Human-robot interaction should surpass a simple user-tool relationship, but be both useful and full of care.

Social Companion

GR-3 is designed to engage with people in public settings. It can act as a service assistant, a comforting presence for children, or a responsive companion for the seniors.

Assistive Companion

GR-3C is expected to expand into assistive practices. Potential applications include research, high-risk operations, and rehab training, bringing support to both work and daily life.

Solid and Robust Performance Base

The GR-3 Series builds on two generations of innovation.

It features advanced motion control, whole-body teleoperation, and a modular design that integrates sensors

and computing units with ease, delivering both precision and reliability for real-world tasks.

Upgraded Hardware Design

Equipped with Fourier's high-performance actuators and multi-DoF dexterous hands, GR-3 handles complex operations with stability and accuracy. Its refined structure is lighter, more compact, and energy-efficient. Dual hot-swappable batteries keep the robot running around the clock, with faster charging and fewer swaps, ensuring uninterrupted performance.

Soft Design, Smart Technology

Beyond emotional intelligence, GR-3 features enhanced hardware and character-rich locomotion—enabling more intuitive and lifelike interactions at every touchpoint.
The GR-3 Series can also support customizable features, including a lifelike standby mode.
Whole-Body Teleoperation

The GR-3 Series supports whole-body teleoperation, enabling real-time mapping of human movements through high-precision motion capture and low-latency transmission.
By extending human reach beyond physical limits, it delivers a new level of interaction and collaboration across diverse scenarios.

Adaptive Framework, Faster Integration

The GR-3 Series features an upgraded backend UI/UX and supports algorithm development on a client-server architecture, which allows researchers, automation engineers and AI developers to get started quickly and tailor functions for real-world use.

Real-World Applications

GR-3 Series marks a new phase in Fourier's pursuit of human-robot integration. It's built to support meaningful interaction across diverse real-world settings, from public services and academic research to clinical use and, eventually, personal spaces. Designed to operate alongside people, the robot adapts to evolving needs and complex environments.
