This is for 12 and under devision
So i have decided to make a very cool gun. This may or may not hurt depending. Please don't point at eyes or intentionally trying to hurt people.

Step 1: What you need

1 mindstorm engine and the controler item (Scene in the upper right of the picture)
2 gears
2 elbow pieces
2 L shape pecies
4 15 doted pieces
4 round connectors
4 round + cross pieces
2 round extra long pieces
1 long cross stick

Ohh, I will show it to my child!!!
now you just need to rig a targeting system :D<br><br>your using the mindstorms kit so perhaps some kind of scanner with the ultrasonic sensor, having it just revolve aimlessly until it senses something within a certain range
I know but I dont know how to program it like that
i havent used the pregraom in a long time but you essentialy have to have something that says motor a keeps turning , then if ultrasinc detects object motor a stops and fire projectile
I would need to be the other way around
this is cool but it is a little simple
I know but it can win the simple bot division. I entered a walking bot too. I am also gonna enter an rc car whith a propain flamethrower
ok i didnt know that it was going into the simple bot one. It might win in that
Well I dont know witch one just guessing
