I always want to build something like this and finaly I had some free time. This is simple drawing robot arm.

It is not very precise because of the servos. But it works.
The software reads plt files (you can create it using ie Corel Draw).

This is what I have used to build it:

1. Arduino
2. three hobby servos
3. pencil
4. paperboard
5. glue

And this is what I get:
