Picture of Big $3 Solderless Bristlebot

Toothbrush sized bristle bots are for kids. Lets take these bots one size bigger and see if we can get them to clean our floors.

Only $3 and takes all of five minutes. Completely solderless to boot.

For a smaller bristlebot kit thats great for adults and kids, visit BrownDogGadgets.com. You'll have a little bristlebot running around your place in no time.

What is a "switch"? It says they're 50 cents at Radio Shack.I searched their website and got many hits, but none looked like what i need.

How long does it really works???

Building them larger is much more fun interesting, in my opinion, the building them small. Plus you can always use it to clean your floor.
cool bristlebot, im gonna make this one too! the only one i have made was from a small toothbrush head and a pager motor! thanks :) !

The motor I pulled out of the dollar store electric toothbrush was surprisingly powerful. I keep forgetting to go and pick up another one.

Post a photo of your finished bot here! I'd love to see.
