I went a little further and installed a VNC server on the Pi and a VNC client on my iPhone, now we have an autonomous EggBot which needs no external computer, keyboard, mouse or monitor — it is all controlled wirelessly from iPad or iPhone. Please see the video at http://www.instructables.com/id/iPad-controlled-Raspberry-Pi-powering-an-EggBot/ .
1) On the Pi terminal, run:
sudo apt-get install inkscape
2) Browse to the Evil Mad Science Labs EggBot wiki page and download the Linux Eggbot extensions and examples.
3) In terminal, run:
sudo apt-get install tightvncserver
4) Follow the directions at http://www.penguintutor.com/linux/tightvnc to add the VNC server to the startup of the Pi.
5) Install the free app “Mocha VNC Lite” on your iPad or iPhone. Now run the EggBot from your iPad/iPhone.
