Current evidence comparison for Fourier GR-2 and Rainbow Robotics RB-Y1.

Fourier GR-2

Fourier

Fourier GR-2 is a second-generation biped humanoid (175 cm, 63 kg, 53 DoF) with 12-DoF tactile hands, FSA 2.0 actuators (peak torque >380 Nm), and developer support for ROS, Isaac Lab, and MuJoCo. Launch coverage from reputable media confirms core specs and teleoperation teaching modes, but no autonomous task execution or customer deployment has been shown. Third-party resellers list it for $125,000, but official pricing is not available. Perception claims of 360-degree RGB camera coverage are reported by one media outlet but not confirmed by Fourier's official launch release

Rainbow Robotics RB-Y1 is a wheeled bimanual mobile manipulator (140 cm tall, 131 kg, two 7-DoF arms, ±0.05 mm repeatability, 20/26 DOF, 1.5 m/s) sold as a research platform for $80,000 (commercial $120,000). It has LiDAR for autonomous movement, force/torque sensors, and supports teleoperation via Master Arm or VR. Evidence includes official specs and pre-order announcement, but no named customer deployments, no autonomous task execution, and all video evidence is title-only without transcript or content review. The robot is purchasable but unproven in real-world use
