Want to make a robot? Watch as Design Squad shows you how to make a mini robot that skitters around the room! For step-by-step instructions visit the Design Squad website.

Here's what you'll need to build your own Bristle Bot!

-1 pager motor with two wires (1-volt to 3-volt motor) No pager motor? Buy one at an electronics store or remove one from a broken electronic device that buzzes or vibrates (e.g., cell phone, electric toothbrush, pager, etc.).

-1 button cell battery (1 volt to 3 volt, to match the pager motor)

-1 toothbrush with bristles set at an angle. No toothbrush with angled bristles? Put a book on top of a head with straight bristles. After a few minutes, the bristles will stay angled back.

-Attachment materials (e.g., rubber band, twist-tie, zip-tie, tape, or double-stick foam tape)

-Pliers/wire cutter

-Wire stripper (optional)

For step-by-step instructions visit the Design Squad website.

Step 1: Cut off the toothbrush head

Snip off the head, using pliers or wire cutters.
Cut the handle close to the bristles.

Step 2: Test the battery and motor

Strip the end of the pager motor’s wires so about half an inch of the metal wire shows.
Touch one wire to the top of the battery and the other wire to the bottom.
The motor should spin vigorously.

Step 3: Attach the motor

Fasten the motor firmly to the top of the toothbrush head.
Use a rubber band, twist-tie, zip-tie, or piece of tape or double-stick foam tape.
Make sure the weight can spin without hitting the toothbrush.
