The Pixel Writer project started with the idea of art spanning city sized units, created with a  temporary medium, and by an instrument that was cheaply reproducible.

The result is a Flash based sketch system. The sketch information is translated into path data with the use of an A* path finding algorithm. The data is submitted with waypoints to a Processing application. The Processing application converts the resulting path data into a form suitable for the vehicle’s onboard Arduino. The vehicle has two motors directly connected to each wheel. Currently, the onboard Arduino drives the vehicle by translating the path into pre-timed motor on-off intervals without a sensor check. The on–off intervals define whether the vehicle is turning left, right, or moving forward.  The final pipeline travels from Flash to Processing to the Arduino.
