B2 robot dog: an exceptional agility and remarkable performance

The quadruped robot B2 from UNITREE Robotics is designed for research and development. The B2 robot dog has been developed with a number of high level technical features:

  • Fast: capable of reaching a speed of 6 meters per second (21.6 km/h)
  • All-terrain: adapts to many types of challenging terrains to ensure steady movements on slippery or uneven surfaces
  • Steady: can climb stairs with extreme stability and balance during ascent, up to 40 cm high
  • Multi-purpose: equipped with knee joint motors providing 360 N.m of torque, 170% increase in joint performance
  • Long-lasting: offers a very long battery life, with uninterrupted walking capability of over 5 hours without a load , and covering a distance of more than 20, representing a 200% increase in endurance, compared to the B1 robot dog

The B2 boasts high-quality equipment:

Ready to use right out of the box, the B2 robot can be used as a research tool in various applications.

A quadruped robot with both legged and wheeled configurations

The Unitree B2 excels in transitioning between leg and wheel modes, surpassing endurance limits. Thanks to its innovative structural design, this transition is made possible, providing unparalleled adaptability.
