Unitree B2

Description

The B2 is Unitree’s flagship heavy-duty industrial quadruped for inspection, rescue and heavy carrying in extreme environments. At about 60 kg with IP67 sealing, very high joint torque and a hot-swappable battery (autonomous charging available), it is built for power/industrial inspection, emergency response and all-terrain work on stairs, slopes and wet surfaces. Perception and user compute expand with configuration, so price is quoted per order. A wheeled variant, the B2-W, is also available on request.
