I would expect the scoring rules would be literally interpreted. The rule says nothing about how the robot is supported, IE another robot, anitgravity, He-balloon, hovercraft. How ever all other rules most be followed.

They do say you have to touch each level in sequence, not supported by. So a brush of an appendage would suffice. G33 allows one robot to be supported by another as long as one of them is in contact with the pyramid. So a robot supported by another could potentially get to zone 3

If you are using a hovercraft, remember that it will power down at the end of the game & come crashing down if not otherwise supported.
