Unitree B2 & B2-W Industrial Robot Dog

Unitree B2

The B2 is one of the fastest industrial-grade quadrupeds available, reaching speeds over 6 m/s while carrying a continuous walking load above 40kg and a standing load of 120kg or more. Twelve joint motors deliver 360 N.m of torque — a 170% jump over earlier models — letting it jump distances beyond 1.6m and clear 40cm obstacles without losing balance. A 45Ah battery gives it 4-6 hours of runtime, covering over 20km unloaded or 15km with a 20kg load, and a quick-swap battery design keeps missions running without long downtime. Rated IP67 and built to operate from -20°C to 55°C, the B2 handles stairs, slopes past 45°, and rough terrain with equal stability — making it a strong fit for power inspection, emergency rescue, and industrial patrol work. Sensing comes from 3D LiDAR, two depth cameras, and two optical cameras for reliable all-terrain awareness.

The B2-W trades legs for wheels, built for efficiency over raw agility. It weighs about 85kg and reaches a top speed of 15 km/h, covering up to 30km unloaded or 25km with a 40kg load on a single 2kWh battery. It still climbs 40cm stairs and 45° slopes when needed, keeps the same 120kg standing load and IP67 rating as the standard B2, and adds high-torque wheel motors (40 N.m, 50 rad/s) for fast, efficient movement across long, mostly flat routes — ideal for warehouse floors, factory corridors, and extended patrol circuits where distance and runtime matter more than obstacle-climbing.
