Who says that your robot always has the same weight? I seem to recall that there was a game in which robots extended a ramp to lift their alliance partners. I also "blue skied" a robot for Ultimate Ascent which would have literally grappled its alliance partners and made a 90 point outside climb (code name Fezzik, for fans of The Princess Bride). If you wanted that same robot to also fly around the field scoring frisbees for the first hundred seconds of the match, having a multi-speed PTO transmission with a total span of 20+:1 would have been epic.
