The Trebuchet


Here is our trebuchet, which we made from the Lego Mindstorms. it uses the NXT brick as the counterweight, and flings little pieces. It has a very simple design, and uses only 1 Servo motor, and the sound sensor. although I have added the 2 extra servo motors to the wheels, and also changed the wheels to treads, I got the design from a website called NXTprojects.com, It is actually called a catapult, but I think it is more like a trebuchet. It is sound activated, so when you make a loud enough noise, it will launch the projectile. So you can yell FIRE!! and it will launch without you even touching it.
