About B1

B1 is a 50-kilogram industrial quadruped with IP68 protection for wet, dusty and outdoor environments. It carries approximately 20 kilograms while walking and substantially larger static loads, supporting sensor, communications and field-equipment integration.

The robot crosses stairs, slopes, loose ground and confined infrastructure through adaptive leg control. Unitree offers autonomous-navigation, inspection and developer configurations with lidar, cameras and onboard compute. B1 has been used for patrol, rescue, mapping, industrial inspection and research, with a removable battery supporting extended field operations.
