Unitree B2

Unitree

The Unitree B2 is an industrial-grade quadruped that combines speed with strength: top running speed exceeds 6 m/s and it can leap more than 1.6 m. Standing payload is at least 120 kg and continuous walking payload exceeds 40 kg; it walks 4 hours and 15 km carrying 20 kg, and more than 5 hours and 20 km unloaded, covering a full day of industrial inspection without returning to dock. It climbs 45° slopes and 40 cm steps directly. IP67 protection with a -20 °C to 55 °C operating range handles rain, dust, cold storage and hot shop floors alike. With dual i5/i7 platforms plus an optional Orin NX, and LiDAR and depth camera fitted, it becomes a mobile inspection workstation.
