WhiteBoard Robot
My roommates and I have over 64 square feet of whiteboard on our wall — a perfect place to build a semi-autonomous drawing robot. We have been improving the mechanical design and adding features very slowly, but it's come a long way:

First Update (Early 2014)
We've finally ordered all the parts and assembled the basic hardware required. There are two stepper motors in the top left and right corners of the whiteboard, each with a pulley and string connected to the marker holder. The motors are controlled by an Arduino Uno, sitting on top of the cupboards.

A closer look at the stepper motor and electronics.

It still needs a bit of work, both in software and an improved marker holder but the general concept is coming to life. The video below shows an early test, where the marker has difficulty returning to its initial position (The shifting pattern was not intentional).
Second Update (Summer 2014)
We've added the ability to draw DXF files and also write any text. More about this later...
