Re: Lego minstorms elastic band gun help

The point of a competition is to design it yourself, isn't it?  wink

The simplest design would just be to have a little hook that holds the rubber band and a second one that holds the other end and releases it. You could also use the ultrasonic sensor to make the bot aim at a target and shoot when it's within range in you wanted.

Good point but his one can fire 20 shots per seconds and hold up to 100 bands
So not going to work your idea

And I only have 1 week to do it
EDIT: 6 days  sad  *AAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHH*

Just make 2 gears on either side of the 'barrel'. Load tons of rubber bands, and connect the gears to motors. There you go. BTW, he probably got it off of youtube. That's soft of unfair.

Look in the official nxt website. There is a community similar to the one in scratch, but smaller.
