Unitree B2
Unitree B2 is a robot for inspection and security.
Unitree B2 is an industrial quadruped for applications including inspection. The manufacturer lists approximately 60 kg including battery and IP67 protection. Unitree reports more than five hours of walking without a load and more than four hours with a 20 kg load. The stated walking load exceeds 40 kg; the much higher standing load is not a transport capacity. Autonomous charging and wheeled feet are optional. Some functions require human operation or custom development.
