Lead The Industry Application

The fastest running industrial-grade quadruped robot at 6m/s. With 170% increase in joint performance and 360 N.m of torque, the B2 delivers extreme performance for greater flexibility and stability in demanding industrial operations.

Unitree B2 Industrial Leader

All-Rounded Terrain Adaptability

Excellent terrain adaptability ensures stable travel on slippery or uneven surfaces. The B2 climbs stairs as if they were flat, handles 20-25 cm continuous stair climbing, and crosses 40 cm platforms with ease. Superior obstacle-crossing ability navigates through wood piles and complex debris effortlessly.

170% Joint Performance Increase

With 360 N.m of maximum joint torque, the B2 achieves extreme performance that provides greater flexibility and stability for industrial operations. A maximum climbing angle exceeding 45 degrees and ditch jumping width of 0.5-1.2 meters make it unstoppable across any terrain.

Wheeled and Legged Forms

Innovative structural design enables seamless switching between legged and wheeled forms. In wheeled mode, the B2-W achieves even greater speed and efficiency on flat terrain, while the legged mode conquers stairs, obstacles, and rough surfaces. The best of both worlds in one platform.

Endurance Limitations

Breaking Through Endurance Limitations

100% increase in sustained load, 200% increase in endurance. Continuous walking with a 20 kg load lasts for more than 4 hours. Unloaded continuous walking endurance exceeds 5 hours with more than 20 km mileage. The 45 Ah (2,250 Wh) battery at 58V voltage delivers unmatched runtime for industrial-grade operations.

Plug-in Battery & Autonomous Charging

The B2 battery supports quick-change design and autonomous charging solutions. Stable and reliable autonomous charging means the B2 can operate continuously without manual intervention. Simply swap the plug-in battery for instant power or let the robot dock itself for seamless recharging.

Exceptional Payload Capacity

Standing load capacity exceeding 120 kg and continuous walking load of more than 40 kg make the B2 a true workhorse. Whether carrying inspection equipment, rescue supplies, or industrial tools, the B2 handles heavy payloads with unmatched stability and endurance.
