Autonomous inspection is the killer app for legged robots, and the math is getting hard to ignore.
The Unitree B2-W specification sheet is dense with numbers. Here are the ones that actually change your buying decision, explained in plain terms.

Weight and size
At 60 kg and 70 cm tall, the Unitree B2-W 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 10 m/s covers ground between checkpoints quickly, while reinforcement-learning gaits keep it upright on stairs, rubble and slopes.
Payload
40 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
4–5 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 IP67, the Unitree B2-W 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?
Small batch and regional variations happen; confirm the current sheet with your supplier before purchase.
