Erle Robot's work with the Pixy camera (CMUcam5).
Documentation of the camera can be found here.
This code provides images from Pixy. This code is based in the orginal code of pixymon
In order to communicate with Pixy over USB as a non-root user you must set permissions for Pixy.
To do this copy the 'pixy.rules' file to '/etc/udev/rules.d'
sudo cp pixy.rules /etc/udev/rules.d/
