Editor's notes

Max speed '>6 m/s' is footnoted by Unitree as achieved only in special configurations with a safety speed limit in practice. Standing load is 120 kg (Unitree) / 80 kg (Maverick); payload recorded as walking load 40 kg. B2 price is on request. Editor may prefer to split B2-W into its own record (as done for Go2-W) since it is wheel-footed; its facts would be legs 4, wheels_or_tracks wheels, wheel_feet true, mass 75.
