I privately considered doing this, but I knew that my team would be against doing it. Too boring for them to build a just-can robot.
A giant fold-out/fold-in polycarb sheet that begins the match out would be enough to drop down onto 4 cans and grab them. I ddon't think any team could grab it faster than that, or at least grab it and pull it with more power than your drivetrain could.
