Unitree As2

Introduced in February 2026, the As2 sits between the consumer Go2 and the heavy B2: a small quadruped built for field work rather than the lab. It weighs about 20 kg with its battery, stands 720 x 378 x 457 mm and runs on twelve joint motors with dual encoders and crossed roller bearings. Unitree sells it in four versions, and they differ far more than the marketing suggests: peak joint torque climbs from 65 N·m on the entry AIR to 95 N·m on the X and EDU, continuous walking payload from 10 kg to 15 kg, standing load from 45 kg to 65 kg, and top speed from 3 m/s to about 5 m/s. Only the X and EDU are open to secondary development, which is how most industrial customers use these machines — inspection routes, sensor carrying and patrol jobs written against the company's SDK. AIR also drops the IP54 rating, ships the smaller 8,000 mAh battery and manages about two hours instead of four. All versions carry an HD camera, wide-angle LiDAR, an 8-core CPU and the ISS 3.0 follow system, except AIR, which has no follow system, GPS or 4G. A wheeled sibling, the As2-W, followed five months later with a heavier continuous payload and far longer range.
