I'm looking at building a control system for electric go-karts at an
entertainment complex I'm currently involved with (Arnold's Family Fun
Center, http://www.arnoldsfamilyfuncenter.com). I have experience
working with micro-controllers and I do
a good bit of programming (mostly c) for a living.

I pretty sure Mr Robot has everything I need. I'm just finding it
difficult to figure out what the packages include and which ones I need.

Essentially I'm looking to build the following:

Customer Service pointed me here with technical questions, so I'd
thought I'd pick some brains a bit.

Any help is very much appreciated. Let me know if anyone needs more
info.
