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).

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.

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
