The servos we have available in FRC aren't quite up to that task, I think--not enough power. You could try using several working together, but that gets complicated in a hurry.

On the other hand, you did get a window motor in the KOP; those are fairly good "high-power servos" if you program them to run for a very short time on a Spike relay. A short-throw, small-bore, pneumatic cylinder may also be a good option.
