This DIY robot was fun to make and surprisingly easy to make. It went off without a hitch, except for cutting the toothbrush end off.
My husband came up with an ingenious way to use friction and heat while bending it back and forth with pliers to cut it. My son trimmed the rough edge with scissors (not really necessary) and then we started the project.
Brush Bots: Turn a Toothbrush into a Robot!
- cell phone vibrating motor
- toothbrush (used is fine)
- 3-volt battery (we used these for our Homopolar Motor project)
- double sided foam tape
- small rubber band
- decorations (googly eyes, pipe cleaners, pom poms)
It might seem hard to find a cell phone vibrating motor, but I found one at Amazon. 5 pieces for $6.
The 3 volt battery is the flat lithium kind. 2 for $1.50 at Amazon.
These are our few hints to build your Brush Bot:
- Make sure red wire is touching double stick tape and blue wire to the side.
- Positive side of battery faces down.
- Now put blue wire on top.
- Tape down.
- Decorate. The decorations help balance the Brush Bot.
Create a maze for you Brush Bot too using a cardboard box.
