About B2-W

B2-W combines four driven wheels with articulated quadruped legs for rapid travel across roads and floors and controlled movement over stairs, slopes and debris. The leg joints adjust body posture, absorb impact and maintain wheel contact across changing terrain.

The platform supports industrial inspection, logistics, emergency response and field research through configurable sensors, compute and payload mounts. Unitree provides development interfaces for navigation and secondary application software. Wheel-leg mobility extends operating speed and access to terrain that blocks conventional wheeled robots.
