Unitree B2-W — Industrial Wheeled Quadruped Robot
Built for the most demanding industrial missions, the Unitree B2-W fuses powerful articulated legs with high-torque drive wheels — rolling at speed across flat ground, then switching to legged locomotion to climb stairs, cross ditches and traverse rubble. With a 120 kg standing payload, IP67 sealing and operation down to −20 °C, it is engineered for inspection, logistics, security and research deployments where ordinary robots stop.
Flexible Movement Across All Terrains
A brand-new intelligent species. Interchangeable wheels and legs let the B2-W adapt to almost any surface — gliding smoothly over pavement, then walking over obstacles the moment the terrain demands it. One platform, every environment.
Highly Dynamic Motion
Self-developed high-performance joints unlock the full potential of the wheel-leg structure. With up to 40 N·m of wheel torque and 50 rad/s wheel speed, the B2-W delivers explosive acceleration, a 1.6 m running jump and confident travel up to 15 km/h.
Stairs, Slopes & Barricades
Combining perception and motor control, the B2-W keeps its balance across discrete, irregular terrain. It climbs continuous 20–25 cm steps, ascends and descends 40 cm stairs in the forward direction, and handles slopes beyond 45°.
Grass, Stone & Gravel Paths
Rapid, synergistic response across multiple leg joints keeps the robot stable on loose and rough surfaces. From gravel tracks to grassy fields, the B2-W stays planted and keeps moving where wheels alone would slip.
