Robot overview

The Apex of Humanoid Dexterity. Fourier GR-2 is a next-generation humanoid platform engineered for high-precision interaction and rapid AI deployment. With its industry-leading 12-DoF dexterous hands and "FSA 2.0" motion control, the GR-2 provides a seamless bridge from AI training to real-world complex manipulation.

Standing 175 cm tall and weighing 63 kg, it moves away from the parallel joint structures of the past to a new serial joint configuration. This shift dramatically simplifies maintenance and debugging while lowering manufacturing costs for large-scale enterprise fleets.

Designed with a "Made for AI" philosophy, the GR-2 features a completely concealed, integrated cabling design that makes the robot more durable in high-traffic environments like reception areas, labs, and light-manufacturing cells. It is the primary vehicle for Fourier’s Open Hardware Interface, supporting a wide range of multimodal AI models and allowing enterprises to customize the robot’s "brain" for specific vertical applications.

Key

Technical Breakthroughs

12-DoF "Bio-Mirror" Hands: The GR-2 doubles the dexterity of its predecessor with 12 degrees of freedom in each hand. These are equipped with six array-type tactile sensors that can identify object shapes, detect material textures, and sense force in real-time, enabling the delicate handling of everything from laboratory glassware to electronic components.
FSA 2.0 Actuator Suite: Utilizing seven distinct types of Fourier Smart Actuators (FSA), the GR-2 achieves a peak torque of 380 N·m. The dual-encoder system in these actuators doubles control accuracy, allowing for fluid, human-like motion even during high-pressure or rapid-response tasks.
Enhanced Power Versatility: The GR-2 features a detachable 950 Wh battery that provides an average of 2 hours of runtime. The hot-swap capability allows enterprise users to keep the platform operational across multiple shifts without long charging delays.
Advanced Interaction Suite: Integrated with a high-performance 14-core CPU and an optional 275 TOPS computing unit, the GR-2 supports real-time voice interaction with echo elimination and vision-based gesture recognition, making it one of the most capable social-interaction humanoids in the 2026 market.

Deployment

+ Scalability

Developer-Centric Ecosystem: The GR-2 is the lead platform for the Fourier SDK, offering pre-optimized modules for machine vision and path planning. It is fully compatible with NVIDIA Isaac Lab, ROS, and Mujoco, making it the standard for universities and corporate R&D centers.
Global Academic & Research Network: Fourier has already deployed GR-2 units at top-tier institutions including ETH Zurich, Carnegie Mellon, and Tsinghua University, creating a global pipeline of researchers developing new "skills" for the GR series.
Streamlined Manufacturing: By redesigning the internal frame to use engineering plastics and aluminum alloys with integrated wiring, Fourier has optimized the GR-2 for faster assembly and higher yield, targeting a significantly lower price point ($125k–$150k) compared to Western high-dexterity rivals.
Modular Deployment: Beyond its bipedal form, the GR-2's upper body and 12-DoF hands are being scaled for stationary "cobot" roles and wheeled bases, allowing enterprises to maintain a unified software stack across different robotic form factors in their facilities.
