OverviewBristlebots are fun little robots that you build on the head of a toothbrush, that buzz around a tabletop like little bugs. You can use them to introduce basic concepts about circuits and engineering. They are easy to build and neither you nor your students need any previous experience with building robots.

Learning ObjectiveAs a result of this activity, students will be able to:
1-2 students. These small robots are ideal for an intimate exploration as individuals or in pairs.
For young students, cut the heads off the toothbrushes and cut small squared of double-sided foam tape in advance.
Follow along with the pictures in this slideshow to assemble your bristlebot:
Disconnect one pair of wires to turn the robots off and prevent the batteries from draining when they are not in use. For long-term storage, cover the exposed metal ends of the battery wires with tape. This will help prevent short circuits if you store the robots together in a box or a bag.
TroubleshootingThe robot stops moving suddenly.
