Final Catapult By Ethan, Evan, Omar, and Jayesh

Task: Finish up the catapult before Arkansas

Today marks six days until Doomsday (AKA Little Home, Arkansas), so we needed to finalize everything. For the catapult, Jayesh and Omar fixed my catapult "fixes". However, with the new fixes, the catapult was more powerful, and required recalibration. To adjust to the new fixes, we removed the old stop-mechanism, and replaced it with a wooden one that stops it on the 2nd level of the robot.

As a result of these changes, the arc of the catapult is more horizontal while preserving the height of the launch. This actually gives us a slight advantage in where we can fire the balls from. The only downside of the new design is that it tends a bit to the left.

Reflections

The catapult is good for this tournament, but we need to pursue alternate designs, such as the flywheel in the future. We should also make better prototypes to test.
