The Fourier Intelligence GR-1 is a general-purpose bipedal humanoid robot developed by a Shanghai company with deep roots in rehabilitation exoskeletons and medical robotics. Unveiled at the World AI Conference in July 2023, the GR-1 stands 165 cm and weighs 55 kg with 40 degrees of freedom and a walking speed of 5 km/h. Availability is currently limited to R&D deployment with select universities and AI companies.

Overview

GR-1 blends steady bipedal locomotion with capable two-arm manipulation for real-world tasks—moving through hallways, climbing steps, and handling small items with repeatable precision. Its perception-driven stack supports safe navigation around people and clutter, while human-scale proportions enable tool reach and workstation access without major re-tooling. Positioned for healthcare pilots, research programs, and light industrial assistance, GR-1 is a practical platform for teams exploring humanoid utility beyond stage demos.

Rehabilitation Engineering Heritage in a Research Humanoid

Fourier Intelligence was founded in 2015 in Shanghai with a focus on rehabilitation exoskeletons and medical robotics. Their existing products — the ExoMotus lower-limb exoskeleton and ArmMotus upper-limb rehabilitation system — required human-safe force control and precision engineering in clinical settings. These foundations carry into the GR-1. The GR-1 was unveiled at the World AI Conference in Shanghai in July 2023 and is compatible with ROS, making it accessible to the broader academic robotics community.

Key Technical Features

40 degrees of freedom enabling human-like whole-body movement
FSA-series electric actuators throughout the body
ROS-compatible SDK lowering the barrier for academic research teams
Force-torque sensing inherited from rehabilitation robotics for safe physical interaction
Camera array for environment awareness and object recognition
IMU for balance and orientation sensing
Walking speed of 5 km/h (3.1 mph)
165 cm height — human-scale proportions

SDK, ROS Compatibility, and Developer Access

Fourier provides a proprietary SDK with full ROS compatibility — a significant practical advantage for research institutions. Developers can leverage existing open-source robotics tools, algorithms, and simulation environments. The platform supports vision-based manipulation, autonomous navigation with obstacle avoidance, and force-controlled interaction. The rehabilitation engineering background means force-torque sensing and compliant control are native capabilities.

Research and Academic Applications

The GR-1 targets universities, AI companies, and research institutions. Primary applications include embodied AI research, human-robot interaction studies, manipulation research for dexterous task learning, and bipedal locomotion algorithm development. Fourier's rehabilitation background also creates potential for healthcare-adjacent research — mobility support studies and clinical HRI.
