Step 1: Build the Bot
Video Tutorials Available: http://coffeeforthebrain.com/brushartbot/
Materials:
• 1x toothbrush - choose one with a large surface area and flat bristles.
• 1x button cell battery or coin cell battery. 1.5V or the 3V ones. They should
both work fine.
• 1x vibrating pager motor - buy one with the unbalanced shaft.
• 1x double-sided foam tape – 1ʺ″ x 1ʺ″ - we will use this so you can experiment.
You can use glue or other adhesives, but this is the cheap easy option for
students to explore.
• 1x scissors - Scissors are to cut tape and sometimes I use to strip wires
being they are quite small. Not the safest but works. Also, they are used to
cut the toothbrushes.
Step 2: How Fast Can You Go?
1. Take your bot to the track.
2. How can you tweak your bot to make it the fastest?
3. Record your run and post to http://padlet.com/coffeechug/brushartbot
4. Be sure to share how you tweaked it to go fast and straight!

2. Option 1: Can you make your bot go in a circle?
Option 2: Can you challenge another bot to a battle in the arena?
Option 3: Can you modify your bot to create art?
Option 4: Can you join forces with another bot to create a superbot?
Option 5: Can you create a bot nobody else has designed or create a new
challenge?
