Claim 8:
9. A system for self-elevating platform control, the system comprising:
a main body structure;
a payload platform for carrying a payload coupled to the main body;
a main lift coupled to the main body and configured to be actuated to retract and extend, where the main lift includes:
a first set of main wheels attached to the main lift,
a second set of main wheels,
a vertical stabilizer attached to the main lift and configured to be actuated to vertically extend and retract the second set of main wheels;

extensible support beams coupled to the main body and configured to be actuated to extend in first and second directions that are lateral to the main body, where the first direction is opposite to the second direction, and the extensible support beams are configured to support a weight of the system;
a first height support coupled to the extensible support beams such that the first height support can be extended in the first direction by the extensible support beams, the first height support having a plurality of first wheels;
a second height support coupled to the extensible support beams such that the second height support can be extended in the second direction by the extensible support beams, the second height support having a plurality of second wheels and the second height support is configured to be actuated to vertically extend and retract the second wheels; and
a controller module having one or more processors and one or more memory devices in communication with the one or more processors, the controller being configured to actuate the main lift, the extensible support beams, the second height support, and the vertical stabilizer, and the memory devices having computer-readable instructions stored thereupon that, when executed by the processors, cause the processors to perform a method for self-elevating platform control comprising, when the system is positioned on an initial surface with at least first, second and third step surfaces, where the first step surface is higher than the initial surface, the second step surface is higher than the first step surface, and the third step surface is higher than the second step surface:
extending the extensible support beams in the first direction to position the first wheels over the second step surface,
contacting the second step surface with the first wheels of the first height support,

extending the second height support until the second wheels contact the initial surface,
retracting the main lift,
shifting the main body in the first direction on the extensible support beams until the first set of main wheels are above the first step surface and the second set of main wheels are above the initial surface,
extending the main lift until the first set of main wheels contacts the first step surface,
adjusting the vertical stabilizer until the second set of main wheels contacts the initial surface,
extending the main lift to raise the main body up from the first step surface,
retracting the extensible support beams to move the second height support in the first direction until the second height support is adjacent to the main lift, and
extending the extensible support beams in the first direction to position the first wheels over the third step surface,
contacting the third step surface with the first height support, extending the second height support until the second wheels contact the initial surface,
retracting the main lift,
retracting the vertical stabilizer,
shifting the main body in the first direction on the extensible support beams until the first set of main wheels are above the first step surface and the second set of main wheels are above the second step surface,
extending the main lift until the first set of main wheels contacts the second step surface,
if the second set of mains wheels is not in contact with the first step surface, adjusting the vertical stabilizer until the second set of main wheels contacts the first step surface,
extending the main lift to raise the main body up from the second step surface,
retracting the extensible support beams to move the second height support in the first direction until the second height support is adjacent to the main lift and above the first step surface,
extending the second height support until the second wheels contact the first step surface.
