Psx Library and dc motors, possible power issue?

Hi everyone! First let me just say I love this site.It's an enormous wealth of information for an enthusiast like me. I have a few concerns with a project I am working on and would love a little input.

An Arduino and a Playstation 1 Controller

I'm having trouble interfacing a playstation 1 controller with the arduino. the project will eventually be to use it  wirelessly to control a simple robot.

I was wondering if anyone has actually gotten the PSX Library on the arduino website to work and if so how, even if it turns an led on and off.

here are some links

A Playstation controller as remote controller

So, suppose i have a couple of those wireless radio serial modules.. I'd like to hook the receiver to my robot, and install the transmitter on a playstation controller. Now, given that i can make a protocol of my own, the question is: how can i interface with the controller buttons&joysticks ? i'd like expecially to read the analogic joysticks.. is it hard ? How is it build inside ?
