An IP67 quadruped platform designed for mobility in demanding environments
The B2 quadruped robot is a platform designed to handle a wide range of environments with strong terrain adaptability: stair climbing, obstacle crossing, and movement on steep slopes.
Fast: capable of reaching a speed of 6 meters per second (21.6 km/h)
All-terrain: it can negotiate obstacles 40 cm high, climb steps 20~25cm high and move over uneven terrain
Multi-purpose: equipped with knee joint motors providing 360 N.m of torque,
Long-lasting: it can operate for more than 5 hours without a charge and cover more than 20 km.
Ready to use right out of the box, the B2 robot can be used as a research tool in various applications. You can also add accessories, for example a LiDAR, a camera, or even the Z1 robot arm to make it even more powerful.
Between leg and wheel configurations
The Unitree B2 is also available in a wheeled version, intended for scenarios where priority is given to travel speed on rollable surfaces and mission continuity over long distances.
Removable battery
The B2 uses a battery designed for stable and reliable power delivery. It allows quick replacement and can also be paired, as an option, with an autonomous charging solution depending on the application’s needs.
