Perhaps you have never been gifted at drawing, or you don’t have the time to do it yourself, so why not let a simple x-y plotter draw for you. This simple two axis device can accurately moves a pen to draw out anything.
The x-y plotter has a two axis control and a special mechanism to raise and lower the pen. The plotter has a hole in its base where the pen goes through. It was designed to print on both paper or any surface such as a wall; simply place the plotter against the surface and the pen will draw away through the hole. Each axis is powered using a single stepper motor and belt. Pen control is achieved using a servo. All electronics are controlled by an Arduino and powered by a 12 volt wall adaptor.
A Demo Video
This video shows a demo of one axis (y-axis) of the plotter moving back and forth. The x-axis was moved by hand to generate curves.
This project was completed by Tommaso Buvoli, Kristina Callaghan, Bruce Deakyne, and Phillip Dunlap for CU Boulder Things that Think Spring 2011.
