Just add a pot for throttle to your pad switches. I am sure you will be unhappy with it, but it can be done. You will need some software intervention for the switches since you do not want to go from forward to reverse at speed. (This tends to tear the tranny out and leave it in pieces on the floor.) The joysticks are something most people have already learned and translating to robot movement come fairly easily for most drivers.
