The B2 is Unitree's pinnacle legged robot, designed for the most demanding industrial and defense applications. With IP67 waterproof rating — meaning it can survive full immersion in 1 meter of water for 30 minutes — the B2 operates in rain, snow, mud, and flooding conditions that would disable other robots. The 360N.m joint torque provides the raw power needed to climb 45-degree slopes, traverse rubble fields, and carry 20kg payloads through any terrain.
IP67 means the B2 is completely dust-tight and can be submerged in 1 meter of water for 30 minutes. In practical terms: the B2 can operate in torrential rain, wade through flooded areas, and be washed down with a hose — making it the only legged robot suitable for all-weather outdoor industrial deployment.
The B2 (60kg, 360N.m, IP67, from $120,000) is nearly 50% heavier with double the torque and full waterproofing compared to the A2 (42kg, 180N.m, IP56, from $52,000). Choose the A2 for standard industrial inspection, and the B2 for extreme environments where failure is not an option. Detailed comparison.
Yes. The B2 can be configured with ATEX/IECEx certification for operation in potentially explosive atmospheres. It can carry gas sensors, radiation detectors, and thermal cameras for comprehensive hazmat assessment. Contact RobotMall for certification requirements.
