Picture of Make a Vibrobot

A vibrobot is perhaps one of the quickest and easiest bots that you can build. In almost no time you can make a fun little bot that makes its ways to and fro across the floor. It is so easy, in fact, that it wouldn't be hard to make a few at once. And then, you can have your own mini private army of vibrobots to do your bidding (assuming that your bidding is to have a bunch of tiny little bots moving randomly to and fro).

Step 1: Go get stuff

Umm... can anyone please tell me if toothbrush with criss cross bristles(like the one used in this instructable) or toothbrushes with flat bristles work better?

You can make both and make them fight to see and let us know the result. :)

I added a switch to mine because the battery was a pain off the "bug to put in," so I figured it'd be harder on. http://www.youtube.com/watch?v=yB8HidxsM7I

Mine just fall over after about 2 seconds and go around in circles. I used a different toothbrush and it would fall about .5 seconds after I set it down. Any help?
Sure man, its all about the weight balance. try glueing something heavy enough from the side opposite to where it falls.
check mine out
I had to balance the bug on it....
i dont know as i haven't made one but what if you tried and did 2 toothbrush bottoms? or maybe used something to cut it so it was completely flat on the bottom?

just a thought
