team 1629 uses two cylinders and two springs to fire the ball.

First the cylinders are charged to extend the springs and lower the scoop (fancy curved catapult) it is then latched with 1 small cylinder. At this point the only force is the springs but as we begin the firing sequence the opposite side of the cylinders is charged (applying force in the same direction as the extended springs) and when the latch is released up the scoop, and what ever may be on it, go. This arrangement gives us gives us the ability to hurdle from ranges back to the end of the lane dividers, as well as the ability to launch diagonally from one homestretch to the other.

Its was a tricky arrangement to control until we discovered that it was much easier to let the programming do the timing required to be efficient.
