i made a catapult that lunched 4 foot high use axles as the arm and for the basket and program it to go about 155 degrees and go backward as fast as it can and it will luanch that high and if you have a new nxt kit it doesnt com with the right angle thing that join ales so you may buy some or there are several ways to with out but not very good
That is unimpressive, sorry to say. You need to not use a motor and use rubber bands, an arm about 1 foot, and a stopping axle instead. In this way it could fire 4 times as far as that one you made. Give it a try. You will like the results.
Would you please send me instructions? david.tarvin@gmail.com. Thanks!

yea nice now you should modify it to make it move and shoot wheneveer it senses some body is close via light sensor or the ultrasonic sensor
