The Unitree B2 is an industrial grade quadruped robot designed for extreme performance, all terrain adaptability, and extended endurance. It achieves a top speed of over 6 m/s, joint torque up to 360 N·m (a 170% increase), and can climb stairs as high as 40 cm and slopes exceeding 45°. With a standing load capacity of ≥120 kg and continuous walking load >40 kg (a 100% increase), it delivers unloaded endurance of >5 hours (>20 km) and >4 hours (>15 km) with a 20 kg load—doubling previous endurance. The B2 features IP67 protection, a 2250 Wh battery, and supports optional wheeled legged switching for enhanced efficiency. Its perception system includes 3D LiDAR, depth cameras, and configurable computing options (Intel Core i7, Jetson Orin NX). Designed for industrial inspection, power inspection, emergency rescue, and other demanding scenarios, the B2 offers robust terrain adaptability and reliable autonomous charging capabilities.
