This catapult is made with the 2016 FIRST Robotics medieval theme in mind to be a handout to other teams at the events. It is lasercut out of a 6.5" x 5" piece of 1/8" thick MDF and requires only a rubber band to function. It also has 3 different pieces that will stop the arm at 15, 30, and 45-degrees away from vertical. The laser will leave partially cut tabs on the pieces so they won't fall out of the board without snapping them out manually so these make great handouts.
