Unitree B2

Unitree's large industrial-grade quadruped, built for heavy payloads, long runtime, and IP67 protection.

B2 is a large industrial quadruped from Unitree Robotics aimed at industrial use, reportedly released in late 2023, positioned to compete with industrial-grade products like Boston Dynamics' Spot. Published specs: about 60 kg including the battery; a standing payload of at least 120 kg and a walking payload over 40 kg; a top speed above 6 m/s, which Unitree calls the fastest among industrial-grade quadrupeds; a 2,250 Wh battery good for over 5 hours and over 20 km unloaded, and still over 4 hours carrying a 20 kg load; and an IP67 dust- and water-resistance rating. It's aimed mainly at power-grid and chemical-plant inspection, emergency response, and outdoor hauling — scenarios that call for heavy payload and long runtime — and can also carry a robot arm on its back for mobile manipulation. The B2-W in the same family is a wheeled-leg version.

ExampleAt a chemical plant, a B2 carries a gas detector and camera to inspect piping corridors in the rain, autonomously climbing stairs to reach an upper platform.
