This is a question not necessarily involving the picture. But are there any rules that specifically state that this right cylinder has to be vertical? Would it not be feasible to say that the robot fits in an (infinitely "tall") cylinder, with the diameter moving vertically, extending into the ground, and above the robot? Basically, just tip the traditional cylinder on its side, and now you have the option for "unlimited" extension, given that you remain under the artificial ceiling imposed?
