Bristle Bots: An Electric Beginning

Posted on

So, we all know electricity is everywhere and we would have a hard time living without it, But do you know what electricity is and how it works?  No?  Well, sit back and enjoy!

Electricity is the flow of electrons that have moved out of its path.  The electrons normally just kind of hangout around tightly packed protons and neutrons.  The magic of electricity doesn’t happen until you give it a pathway to flow called a current.

Unfortunately, our body can be a pathway for electricity to travels.

Our class has been learning about electricity so we can understand how bristle bots work.  Basically, a bristle bot uses a closed electrical circuit to power the motor that causes the bristle bot to work. 

Using a pager motor, two wires (the current), and a double A battery (the electrical source) we made an electrical circuit.  We hot glued this to two toothbrushes.  Then we had to put our personal stamp on it and added pipe cleaners and google eyes.  Wah-la!  The birth of a bristle bot.  Take a look:

Ahhh, cute, right?  So, what do we plan on doing with them?  Well, we are going to race them!  Stay tuned for the races…you won’t want to miss them.

What do you think would happen if we didn’t have electricity?  

What would be some ways we would have to adapt?
