How do I give a radio control car autonomous control

[Kenjones1935]

I have the car. It uses a Tomahawk Reverse Electronic Speed Controller(http://www.nosram.com). I want to use that system directly from the RC receiver for racing. It is proven and its response is sure. It would be nice if I could get the same three wire sockets that this device is accustomed to plug into, but that seems more than I can expect.

I plan to use DPDT switches to toggle between RC receiver control and PIC control. I plan to use the third channel on the RC system to tell the PIC to flip the DPDT switches.

The attached pictures of the car show that it is four wheel drive (there is a drive belt down the middle). This limits my ability to attach the PIC and attendant devices. Once the PIC control works I will be able to get more appropriate 1/10 scale cars or trucks.

I hope the pictures came out OKAY.
