To koreabell:
Thanks for taking the time to actually go down the code step by step. I've been a bit busy over the holidays and I've only gotten to read what you wrote now.

To everyone:
One thing I noticed so far in the code, is the use of an "Arcade Joystick". Is that referring to "tank-drive" type steering or to single joystick control of the robot? Also, is it possible to use a different type of steering mechanism, for example a steering wheel, to control the robot? If so, what other resources would I need and how will I be able to implement it in the source code?

Thanks for your time. I look forward to reading your replies.
