Unitree B2

The B2 is the working machine of the three. 120kg maximum payload and 6 m/s are industrial figures, and the 45Ah battery gives more than four hours of continuous walking while carrying 20kg, which is what determines whether a shift can be completed without an intervention.

The realistic applications are inspection and carriage over ground a wheeled platform cannot cross: substations, plant, construction sites, anywhere with stairs, kerbs or debris. Endurance is what makes those viable, not speed.

At 60kg it is not a machine to move casually, and at 1098mm long it needs real storage and transport arrangements. Worth planning for before delivery rather than after.
