1. The machine must be stationary.
2. The machine must operate without human aid – only the pushbutton and potentiometer may be touched in order to launch the ball.
3. The machine should be able to re-load and launch a second ball without the need of human aid other than touching the pushbutton or potentiometer.
Here is one of the catapult kits (the potentiometers have not arrived yet):
The Arduino catapult competition was held on Friday, November 16. There were four working catapults, but all four violated the rules in some way.
Fourth Place: 7' 10.5"
Third Place: 9' 11"
Second Place: 12' 5.5"
First Place: 12' 8.5" (the ramp was damaged after testing)
