Instructables
Picture of Arduino Drawbot
In some of my previous Arduino instructurables I have show to the Arduino beginers on how to control servos in different ways.
And in my last instructurable I have show the modification of a Parallax servo for a 360º rotation.
So in this one I will show Arduino beginers the use of those 360º rotation servos.
With that in mind we will make our first ROBOT. It will be a simple bot called The DrawBot
For the some of the materials just look around the house and recycle it for the DrawBot to be made
NOTE: The code and the idea was taken from around the internet. And again there are tutorials showing you this simple DrawBot or the 5 Minute Drawbot but they're not clear enough for the beginner. All the electronics were bought @ RADIOSHACK.

Enjoy ;

The following will be divided in categories and in no particular order:

Tools:
          1.  Drill with a drill bit (size depends on the diameter of the marker)
          2.  Screwdriver to attach the wheels to the servos.

Hardware:
          1. (X2) spray paint can caps.
          2. (X2) small screws
          3. (X3) rubber bands
          4.  Piece of wood ( size, shape and thickness could be any to fit all the parts)
          5. Arduino UNO Rev3
          6. Breadboard
          7. (9V) battery
          8. (9V) connection harness to provide power to the Arduino.
          9. (X4) wires for all the connections.
         10. A marker ( any color)
         11. (X2) Parallax Servos with the 360º MOD
         12. 12 pin connector         
         13. USB cable to prgram the Arduino.
         14. Something to add traction to the wheels ( I have use from lego, two rubber tires, but you can use any electrical tape also).

Software: 
               Arduino software (to upload the code)

this is such a good idea! could try 4wd + rotating pen. keep up the good work!

The code was from the arduino web site

Great, thanks!

very interesting and amazing. Can't we develop this project with a 3D scanner. It means first scan the image and draw it. I think you have a idea. I am waiting from your response.God Bless and Grate day.

umm!!! interesting I will try something like that

where did you get the code from?

You are very right JoshuaZimmerman
Or you could just buy a really small 9V to 2.1mm plug connector. Simple and easy to use.

You can also find connectors with built in switches and hard cases.

How do you go about plugging a nine volt into the arduino? Which ports do I use?
biomech75 (author)  ElectroFlex2 years ago
1. You need this connector for the battery look at the link for a clear picture
http://www.radioshack.com/product/index.jsp?productId=2062218
2. And this picture will help you see the connector to provide power to the arduino.
3. And here is were you connect the 9V battery to the Arduino.
