Why your all confused:
-using powered wheels makes your design more like a catapult. Its more about the power you connect to make an engine or a single wheeled catapult.
-making it green makes it more like a trebuchet because your using unattached weight, and using a pivoted arm makes it exactly like a trebuchet. You've been building them all along!
there you go--Nick
