Weight and size

At 15 kg and 40 cm tall, the Unitree Go2 Air is portable enough to lift into a vehicle yet stable under load. Size drives where it fits: doorways, lifts and confined spaces.

Speed and agility

A top speed of 3.7 m/s covers ground between checkpoints quickly, while reinforcement-learning gaits keep it upright on stairs, rubble and slopes.

Payload

8 kg of payload is the budget for your sensors, a small arm or a delivery box. Plan the mount and the weight before you buy the accessories.

Battery and runtime

2–4 h of runtime is realistic for mixed work; keep a spare pack for continuous coverage. Runtime drops with speed and payload, so test against your real route.

Ingress protection

Rated indoor / light outdoor, the Unitree Go2 Air handles the working environment accordingly. Match this to where you will actually run it.

Frequently asked questions

Do the numbers include payload?
No. Payload, speed and runtime interact; the sheet lists them separately and real life is the combination.

Are specs identical worldwide?
