Balancing enables it to be any height without increasing footprint or hence weight. The camera can be at human height, but only take up as much floor space as a human. As an example, the Beam Pro does not balance, has 4 wheels and weighs over 100 pounds with a camera at 5&#x27;6&quot;. Anybots QB weighs about 35 pounds and can have the camera at 6&#x27;2&quot;.<p>It also enables added mass without changing the drive system. So instruments and equipment can be added.
