ok, so what I'm understanding, is that you want an RC Robot, right?
Well, I'm an RC expert! I have numerous hobby level RC cars (nitro cars, electric cars, and 50+ mph cars!)
What you need to do, is buy your self a reciever and remote (RX, and TX) If you only want to run two motors/servos, you will only need a 2 channel set, but if you want to run more (ie, controlled lights, more motors/servos) you need more channels. You can buy these remotes fairly cheaply, but if you are running motors, you are going to need a ESC (electronic Speed Control).
This is most likey making no sense to you, but if you are interested in what i'm saying, just pm me, and I can get you links to these parts.
