How to Make a Homemade Robot in Under 5 Minutes with a Toothbrush

This is really cool, today we’re going to learn how to make a little robot out of a few very small, simple, and cheap parts you likely can find around the house. Honestly, I’ve found that once you get the stuff together it takes less than 5 minutes to do, and believe me you don’t need to be a mechanical engineer to do this, this is something that could be a cool science project for a 5th grader or something, for real, it’s just that

would be so cool to have on your desk if you’re in any kind of technical field–just hold up your homemade bristlebot and tell clients it’s the latest cutting edge technology from your company

Ok, here’s what you need:

• The head from a toothbrush (must have slanted bristles)
• A watch battery




• A “pager vibrator motor” (this is the thing in cell phones that makes them vibrate when a call comes in if you’ve got your phone in vibrate mode–you’ll likely have an easier time extracting one from a cheap old cell phone than a pager as no one really uses pagers anymore). Also, a pager motor is just a small DC motor with an offset weight on the axel, so you could just make one yourself out of any type of DC motor that’s small enough.
• Foam tape

And here’s what you do once you’ve got that stuff:
