A BrushBot is a mechanical toy powered by a simple circuit with a pager motor that vibrates and moves the bot across many surfaces, like tables and floors. Toothbrushes may be inexpensively purchased, and in bulk, online. For stability of movement, try lashing two toothbrush heads together with sticky tape. Unlike real robots, this version of the BrushBot isn’t programmed; but, it could be with Arduino. Start simple and then surprise yourself and others by inventing a completely new version of this fun toy! See the links below for more inspiration. See “How To” on Maker Kids for a video demonstration of BrushBot making.
Check your kits: four toothbrushes, two pieces of double-sided tape and four batteries with wires
If the bristles are uneven, trim with scissors until they stand flat on a surface.
- After you build your BrushBots, mod them for more fun!
- Connect 2 bots together with tape or a bit of wire.
- Trim or bend the bristles to make the BrushBot change direction.
- Add stabilizing wire legs. This way the BrushBots can crash into each other without tipping over.
- Make up a racetrack and see whose BrushBot wins!
