Step 3: Add markers
Hmmm...What colors to use?
After you have decided what colors to use, simply insert the markers in the holes.
If your markers are like mine you will find that as you insert the markers, they will start to fit tight in the holes. This is another way that you can continue experimenting with DoodleBot360. You can insert the markers in at different heights to get it to go different directions.
You can make an arena using video cases, and watch it work its way around.
Have fun with your DoodleBot360!
