How to Make a Better Bristlebot!

A bristle bot is a fun little robot that you can make out of a few things around the house.
They are really quite easy to make and are a lot of fun!

Many Bristlebots are the same, mine is different!

I will be teaching you how to make a Bristlebot using a Pulsar Oral B Toothbrush!

These new Bristlebots also look really cool!

Step 1: Supplies & Tools

Picture of Supplies & Tools
Supplies

1. Pulsar Oral B Toothbrush
(the reason we need this brush is because there is a tiny vibrating motor inside which will be powering our little robot!)
2. Double Sided Adhesive Tape
3. 1.5V Button Cell Battery

Tools

1. Wire Stripper
2. Scissors
3. Tiny Scissors
4. Pliers/Wire Cutter
5. Heavy Object (book)

Step 2: The Toothbrush

The first thing you will do it take your toothbrush and remove the battery cover and take out the battery inside it.
Hey! Now you have a spare AAA battery! (Figure 1.1 & 1.2)

Use your pliers to remove the guts of the toothbrush. This may take some force but don’t worry you won’t break the motor. (Figure 1.3 & 1.4)

Once you have removed the guts of the toothbrush take your pliers and use the wire cutting part to cut the head of the toothbrush of off the body. (Figure 1.5)

The bristles are facing strait down but we wish for the to have an angle.
Place a book on top of the toothbrush head.
(Make sure the bristles are facing towards the uncut end.) (Figure 1.6 & 1.7)

Step 3: The Guts!

Now take the guts of the toothbrush and bend back the plastic encasing the motor, and also pull off the plastic covering the blue wire. (Figure 2.1 & 2.2)

Should you cut the blue wire or the red one?... Both!
Cut both of the wires with your small scissors and remove the motor from the plastic. (Figure 2.3)

Now that you have the motor you will need to strip the plastic off the wires. Do this using a wire stripper. (Figure 2.4)
