Introduction: How to Make a Pocket-sized Bristlebot

In this Instructable, I will show how to make my version of a bristlebot.

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 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)

Step 2: Assembly

Take your piece of foam tape, and put it on top of your toothbrush head.Then place your motor on top of the toothbrush head, making the weight stick out over the top of the toothbrush head.Then stick a wire from the motor on to the foam tape and put the battery over it (any way). Stand it up and make sure it is well balanced. You are done!

Step 3: How to Use It

Just place the other wire over the battery and it should work. Enjoy!

    hey can u send me a link to buy tht pager motor?

    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.

    i never knew that also did it

    its still cool though-- i like how he used a toothbrush head O_o

    Rick Harris- this robot has been around LONG before 'Ibles and to credit the first maker would be virtually impossible. Seriously! Are you the official you-didn't- make-it-first-so-you-suck person on instructables? stop with your sarcasm and think- did kill1234 REALLY offend the world by not crediting the original builder? Is the original builder going to care enough that the entire world's going to explode because he wasn't credited? (This is assuming the Original builder isn't already DEAD.) I'm sure if kill1234 knew who built it first he would have said. Seriously... oh yeah- thankyouandhavaniceday. -AdmiralCubie
