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

Tiangong Ultra

Beijing Humanoid Robot Innovation Center (X-Humanoid)

Tiangong Ultra is a bipedal humanoid research prototype from Beijing Humanoid Robot Innovation Center (X-Humanoid), standing 1.8 m and weighing 55 kg (or 52 kg per BaiduWiki). It won the world's first humanoid half-marathon in April 2025 (21 km in 2:40:42) and has demonstrated climbing 134 stairs, navigating rough terrain, and sprinting 100m in reported times as low as 8.64s. However, autonomy is only claimed, manipulation and endurance specs are unknown, and the robot is not for sale. Strongest evidence is the half-marathon win with media coverage; weakest is missing manipulation, commercial deployment, and verified autonomy
