Fun Projects for your LEGO® MINDSTORMS® NXT!
|This catapult works similar to some of the original
catapults back in the days of castles and swords. The NXT brick
acts as a heavy weight that is raised up when the catapult is "cocked",
then when the trigger is released, the NXT brick falling just a few
inches produces enough power to fling small pieces across the room!
In a modern twist, this catapult's trigger is sound
activated. After cocking it, stand back, then clap your hands or
yell "fire" and it fires on command!
