The Unitree B2-W is an industrial-grade wheeled quadruped that fuses legged agility with high-speed rolling locomotion. Its structural design switches seamlessly between walking and wheeled modes, letting it sprint across flat ground at roughly 20 km/h while retaining the stair-climbing and obstacle-crossing ability of a legged robot. With a 120 kg standing load capacity, a moving payload above 40 kg, and high-torque joints rated up to 360 N·m, the B2-W is built for demanding real-world deployment rather than the lab.

An IP67-rated body and a wide -20°C to 55°C operating range make it suited to inspection, logistics, security patrol, and emergency response in harsh outdoor and industrial environments. The 2250 Wh (45 Ah / 58 V) battery delivers around 4-6 hours of operation and up to ~50 km of range (max endurance with a 40 kg load), while onboard Intel compute plus optional NVIDIA Jetson Orin NX modules and a 32-line automotive-grade LiDAR option support autonomous navigation, perception, and custom application development.
