Tiangong vs Tiangong Ultra

Tiangong is the first full-size biped from the Beijing Humanoid Robot Innovation Center (X-Humanoid), publicly shown on 2024-04-27 as an open, research-oriented platform: 163 cm, 43 kg, fully electric, with a 48 V/15 Ah pack, 3D vision sensors, a high-precision IMU, six-axis force sensors and a claimed 550 trillion operations per second of onboard compute; a directory records 20 total DoF for the launch configuration. The public evidence is essentially locomotion — a claimed stable 6 km/h run and slope/stair traversal described as 'blind' — with no manipulation (the launch robot is reported to lack human-like hands), no task autonomy, no endurance or reliability data and no human-interaction evidence. It is research-only and not for sale, and has been superseded by later Tiangong variants (1.1 PRO, 1.2 MAX, Walker, Ultra, Omni, 2.0, 3.0) whose records must not be credited to this robot

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
