If you are short enough that it handicaps you, then this counts as a "disability" (magic word!) and you can bring whatever equipment (such as a stepstool) is needed to overcome this disability.

"An individual with a disability is defined by the ADA as a person who has a physical or mental impairment that substantially limits one or more major life activities, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment." - ada.gov

Decide whether your height substantially limits your ability as a robotics coach. If it does, then talk to the Head Referee. He/she will ask you if you are disabled. Answer "yes" and you can use the stepstool.
