Question 1

1. What is GR-2, and what problem is it designed to solve?

Accepted Answer

GR-2 is a 175 cm tall, 63 kg humanoid robot developed by Fourier Intelligence, designed to perform complex bipedal locomotion and dexterous manipulation tasks across research, industrial automation, and embodied AI applications where human-like movement and precision handling are required.

Question 2

2. What are the main capabilities and key features of GR-2?

Accepted Answer

GR-2 features 53 degrees of freedom including 12-DOF hands with six tactile sensor arrays, FSA 2.0 actuators delivering peak torques exceeding 380 N·m, walking speeds up to 5 km/h, single-arm lifting capacity of 3 kg, and adaptive grasping with real-time object recognition via force sensing.

Question 3

3. Who is GR-2 built for, and which industries can benefit from it?

Accepted Answer

GR-2 targets robotics researchers, AI developers, and industrial operators in manufacturing, healthcare, and automation sectors. The platform supports academic research, embodied AI exploration, industrial process automation, and real-world application development through its open software architecture.

Question 4

4. Is GR-2 a commercial product or still a research prototype?

Accepted Answer

GR-2 represents a transition from prototype to commercial deployment. According to the manufacturer, it moves beyond the prototype stage as a more capable and adaptable solution, though it remains positioned primarily for research institutions, developers, and early industrial adopters rather than mass consumer markets.

Question 5

5. Is GR-2 currently available for purchase, and when is it expected to ship?

Accepted Answer

GR-2 is available through Fourier Intelligence and authorized distributors. Specific shipping timelines depend on distributor fulfillment following orders, with availability varying by region and application requirements.

Question 6

6. How does GR-2 actually work in real-world environments?

Accepted Answer

GR-2 operates through a dual-encoder control system that enables precise joint movements in dynamic settings. The robot uses visual perception with SLAM (Simultaneous Localization and Mapping) capabilities, tactile feedback from hand sensors for adaptive grasping, and supports multiple control modes including VR remote operation, lead-through programming, and direct command execution.

Question 7

7. When was GR-2 announced or officially launched?

Accepted Answer

GR-2 was announced as the successor to Fourier's first-generation GR-1 humanoid robot. The company released detailed specifications and began initial deployments in 2024, positioning it as an upgraded platform incorporating customer feedback from earlier-generation systems.

Question 8

8. How is GR-2 different from other robots in the same category?

Accepted Answer

GR-2 distinguishes itself through seven types of specialized FSA actuators tailored to specific joint torque demands, integrated cabling for compact design, and 12-DOF hands with tactile sensor arrays. The redesigned internal joint configuration from parallel to serial improves debugging and manufacturing efficiency while supporting seamless transition from AI simulation to physical deployment.

Question 9

9. Does GR-2 require additional development or customization after purchase?

Accepted Answer

GR-2 is designed as a developer-friendly platform supporting open-source frameworks including ROS and NVIDIA Isaac Lab. The Fourier Toolkit SDK provides pre-optimized modules and intuitive APIs, enabling research teams and developers to customize functionality and develop task-specific applications without extensive additional engineering.

Question 10

10. What is the future roadmap or planned upgrades for GR-2?

Accepted Answer

Fourier has announced plans to expand GR-2 availability from early commercial deployments toward broader industrial adoption. The company continues developing enhanced capabilities in AI-driven motion planning, environmental interaction, and integration with existing manufacturing and research infrastructure based on customer feedback and real-world deployment data.
