***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.

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?

haha that's awesome.Does anyone know if I can make a bristlebot with my toothbrush? (it's a malibu bright 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.

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.
