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

You will need

- 3VDC Micro-Vibration Motor (Model: 273-107 | Catalog #: 273-107)
- CR1220 Coin Cell Dip Type Battery Holder (Model: 270-008 | Catalog #: 270-008)
- EnercellĀ® 3V/225mAh CR2032 Lithium Coin Cell Battery (Model: CR2032 | Catalog #: 23-802)
- Toothbrush

Step 2: Strip Wires

Trim the wire leads of the vibrating motor shorter. Strip away a bit of the protective jacket to expose the copper wires.

Step 3: Solder

Solder the red wire of the 2032 battery holder to the positive pin of the battery holder.

Solder the black wire to the ground (minus) pin of the battery holder.

Step 4: Cut

Use your diagonal cutters to cut the toothbrush head from the toothbrush handle.

Step 5: Hot Glue

Hot glue the motor and battery holder to the flat plastic part of the the toothbrush head.

Step 6: Power!

Insert the 2032 battery and watch it go.

    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

    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. :)

    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 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
