2098B (first year middle school team from Waukesha STEM academy in WI) went to 2011 Vex worlds with zero autonomous modes working correctly. By Thursday morning they had a 5 ring score working. By Thursday afternoon it became clear that more modes were needed. Plan C was a quick score with a preload that also blocked the floor goal. The kids were particularly pleased because it was conceived and developed in the space of one day.
Congrats to all of the great teams at Worlds and hope to see you guys next year.
