    Thanks for the information. I had already put a little thought into this and have already purchased a linear actuator with feedback. Here is the link to the site http://www.pololu.com/product/2319 and the part number Concentric LACT4P-12V-5.

    I want to use a PID loop to control the steering and drive motor speed, so I decided to go with the linear actuator above and I plan to use a Hall effect switch to get a RPM signal from the drive train.

    Any suggestions for some information on a script or other application to pipe the signal from the game controller (USB connection to the PC) to the Wi-Fi port on the PC?

    Thanks for the warm welcome and advise Jason. As you can see from my reply to WYLDHUNT, I am moving in the direction you are suggesting. Also thanks for the links to resources, very much appreciated. I am sure I’ll be back with more questions.

    I think I should also mention that this is the first forum that actually responded to any of my questions; Hats off!!

    Thanks for the encouragement and information WYLDHUNT, truly much appreciated. I was probably not clear enough on a few details, so allow me to clarify.

    I had planned to have three different communication networks; PC to microcontroller Wi-Fi, RC tx/rx (with wired communication from rx to microcontroller), and separate wireless IP camera.

    Since I posted this a few days ago I determined (and you have concurred) that using the RC system was going to be disjointed and clumsy. I am leaning toward using a game controller with USB connection to the PC and then pushing that message to the microcontroller via wi-fi. I should add that I will probably be using a Freescale Tower microcontroller system because I already have one and am somewhat familiar with C language.

    Trust me space under the shell won’t be a problem, do a quick web search for Power Wheels cars. The steering is a concern, but not as much because the car is not going to be autonomous. If I did do the steering with the rear wheels I would need to come up with some way to control how the front wheels turn. I have seen some other folks use a linear actuator to control the steering, that is the route I plan at the moment, but we’ll see : )

    Thanks again, I’m sure I will have plenty more to ask!
