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 5'6". Anybots QB weighs about 35 pounds and can have the camera at 6'2".

It also enables added mass without changing the drive system. So instruments and equipment can be added.
