Fourier has introduced the GR-2, the latest addition to its GRx robot series, incorporating advancements in hardware, design, and software based on customer feedback. The GR-2 features an integrated cabling design that enhances its compactness and streamlines power and communication transmission. This new configuration reduces debugging time and manufacturing costs, while improving the transition from AI simulation to real-world applications.
Standing at 175 cm and weighing 65 kg, the GR-2 is equipped with a battery offering a two-hour operational duration. A key upgrade is the introduction of 12-DoF (degrees of freedom) dexterous hands, which provide twice the dexterity of earlier models. These hands are designed to replicate human flexibility, making the robot better suited for complex tasks that demand precision. In addition, the robot features six array-type tactile sensors that enable real-time adjustments based on the shape, material, and force required to manipulate objects.
The GR-2 is powered by seven distinct FSA (Flexible Series Actuator) units, each specifically tuned for different joint torque requirements. The FSA 2.0 actuator, capable of generating over 380 N.m of torque, features a dual-encoder system that enhances control accuracy, particularly in dynamic environments. The robot can achieve speeds of up to 5 km/h.
To aid developers, Fourier has enhanced its Software Development Kit (SDK), allowing for easier access to a range of pre-optimized modules via intuitive APIs. The platform supports development frameworks including NVIDIA Isaac Lab, ROS, and Mujoco.
Fourier continues to collaborate with companies and research institutions, such as ETH Zurich, Texas, Carnegie Mellon University, and Tsinghua University, to explore the capabilities of humanoid robotics in various industries.
