The Unitree B2 is a heavy-duty industrial quadruped engineered for the most demanding inspection, logistics, and field-operations workloads. With a standing load capacity of 120 kg and a continuous walking load exceeding 40 kg, it carries serious payloads while sustaining a top running speed of over 6 m/s, making it the fastest industrial-grade quadruped in its class. A peak joint torque of around 360 N·m delivers the raw power behind its mobility and load-bearing performance.

Rated IP67 for full dust and water resistance and operational from -20°C to 55°C, the B2 is built for harsh outdoor and industrial environments. It clears 40 cm obstacles, climbs slopes over 45°, and traverses 20–25 cm stairs with ease. A 45 Ah (2250 Wh) quick-swap battery provides 4–6 hours of runtime and over 20 km of unloaded range, while an integrated 3D LiDAR, dual depth cameras, and dual optical cameras feed autonomous navigation and perception, supported by Intel Core i5/i7 onboard compute for platform functions and user development.
