A practice of picking up the ball and launching it.  The catapult design is not our final version.


After we finished the catapult we wondered why it was shooting so high with not very much range.  It runs out the ball was rolling off the back edge thanks to footage from an iphoto slo-mo video.  So we just added an extension to the back of the basket and we were then shooting at about a 45º angle.


Autonomous practice with the revised catapult basket.
