Robots can do some pretty cool things. Some sing and dance, others sweep your floor and mow your lawn. Unfortunately most are so complicated that the average person couldn’t dream of building one from scratch. Don’t be too dismayed though, you can construct your own bot from items sitting around your house. Sure, it might not serve any functional purpose, but that doesn’t diminish the fact that you made it with your own two hands.

The Bristlebot it a little robot built from a Pulsar Oral B Toothbrush. If you happen to have one of these that you’re about to discard, then this is the perfect little project to work on. Just be sure to clean it first. You’ll only need a few tools, some double-sided tape and a 1.5V button cell battery. When you’re finished, you’ll have a little bot that can move itself about, thanks to the vibrating motor of the toothbrush. If you’re feeling artistic, you can dip the bristles in some paint, and let it work its magic on a canvas.
