The AgiBot X2 — sold in China as the Lingxi X2 — is a 1.31 m, 35 kg bipedal humanoid from AgiBot, one of China's largest humanoid-robot startups. Launched in 2025, its headline feature is being full-stack open source: AgiBot released both the hardware design and the software, including its GO-1 vision-language-action foundation model trained on the openly published AgiBot World dataset. The base X2 carries 25 degrees of freedom, a swappable 500 Wh battery good for roughly two hours, and a modest RGB-camera sensor suite, while the X2 Ultra adds LiDAR, depth cameras, and autonomous docking. AgiBot has shown it walking, running, cycling, and balancing on a hoverboard. At around 4,240 through Western resellers it is positioned squarely at researchers and developers rather than consumers. We have not tested a unit, so this is a specs-based assessment.
