Robotic Car follown an object

[KChampion]

I am trying to figure out how to have a robotic car follow and object. The Distance would be 3 feet between the car and the object. It would be on hardwood floor, no carpeting, it would be indoor just flat hardwood floor, i also am trying to avoid obstacles and interference so i would wanna use RF. The maximum speed would be walking speed and i am using the PIC16F84A chip and program. Also I am trying to figure out how to have the car turn so it would not tip over. I would need the car turn left and right and possibly reverse.

Thanks Hope someone can help.

I made one using a PIC16F628 and two cds and it kinda worked. I wanted to make it follow dark areas but when I stood infront(3 inches away) of it and moved left or right it followed me and I was supprised. But Im still working on it.
