About B2

B2 is a roughly 60-kilogram industrial quadruped capable of running at up to six metres per second. Joint torque reaches approximately 360 newton-metres, supporting repeated stair climbing, 40-centimetre obstacles and slopes above 45 degrees across uneven or slippery terrain.

The robot carries more than 40 kilograms while walking and can operate for over four hours or 15 kilometres with a 20-kilogram load. Lidar, cameras, communications and payload interfaces support inspection, patrol, sensing and transport configurations, while an optional wheeled version extends range on prepared surfaces. B2 is sold as a civilian industrial platform requiring application-specific autonomy and payload integration.
