***UPDATES!*** (as of July 20, 2009)

I found the perfect toothbrush head!
Use the Exact Cross-Bristle Toothbrush I found at Superstore and it will go straight!

I give most of my credit to http://www.evilmadscientist.com because I discovered his bristlebot after I published this Instructable.

Step 1: Materials

Here are the materials you need:
-1x vibrating pager motor
-1x toothbrush head (bristles have to be angled as shown in picture 2)
-1x cell battery (any type, has to be between 1-9 volts)
-a piece of foam tape (already attached to top of toothbrush head)
hey can u send me a link to buy tht pager motor?
I took apart an old pager...
I am desperate to find a good toothbrush to use!! I have been making them with kids and they don't work right with the average bristles.  I have been searching on the internet for the toothbrush that you recommend, but I can't find it at all! Is 'Exact' the brand?  And what is Superstore?  IF you can help me I will be eternally grateful!! Thanks so much for a great Instructable!
Do you live in US, because I found this toothbrush in Superstore in Canada. Nevertheless, find a toothbrush with bristles that criss-cross with each other.
You can make ordinary bristles work, all you have to do is bend them back to make the bot go forward.This also works with turning, bend the front bristles left to go right and right to go left, for added speed trim the bristles a tiny bit on a slope with the front ones a little shorter than the back ones.
What is the Exact Cross Bristle and What is Superstore?
The simple style <a href="http://www.ugglinks.com/" rel="nofollow"><b>UGG Boots</b></a> is just like the Eskimo fur coat and its style is suitable for all people, that is to say that ugg boots did not have so clearly difference between men and women. Accurate to say, it is the Australian wool workers shaving who wear <a href="http://www.ugglinks.com/ugg-classic-tall-fancy-c-86.html" rel="nofollow"><b>UGG Classic Boots</b></a> first in the earliest time. Winter is so cold and I think there is nothing more important than keeping warm. So ugg boots can be your good decision because it is famous for keeping warm.

haha that's awesome.Does anyone know if I can make a bristlebot with my toothbrush? (it's a <a href="http://www.malibubright.com" rel="nofollow">malibu bright</a> brush, it already has a motor so I'm pretty sure that's all I need, right?)
I took apart a cell phone but no motor. What cell phones work?
Most cell phones vibrate but some have a round vibrator like a small coin rather than a regular motor and weight. It will still work though.
ones that vibrate when you get a phone call
And how is your version different from the original which you don't credit?
Thanks for including the credit and all credit to you for the re-invention. :-)
there are a lot of different instructables out there about bristlebots and it would be challenging to reference them all. he just might not have seen the original.
where is the motor?
Goggle &quot;pager motor&quot; you can buy them online&nbsp;for about a buck
I made two of these last year. one of the motors burned out and stopped working but the other one still works to this day.
Those vibrating motors are also in some electric toothbrushes
yea but I don't know where to get the pager to dissasemble!
where can i get a cheap vibrating pager?
you can either disassemble a pager or buy it from ebay.
I like it. Simple, yet fun.
