Steve,

I had hoped that I could prototype with Microchip's PICkit 2 Debug Express. That may not be practical.

First off FEDEX or whatever has to deliver my PICBASIC PRO software package. Then I need the DPDT switches I'm getting from Newark. Then I need to master the programming. I want to use the DPDT switches to toggle the signals into the rear wheels electronic speed control (ESC) and the steering servo between the radio receiver and the PIC.

I also may need two battery packs. The ESC uses a 7.2 volt Ni-Cd pack. The PIC needs a 5 volt arrangement. I could put a 5 volt regulator in front of the PIC. Trouble is the 7.2 volt batteries do not last very long when at the track. Two voltage sources would be preferable but more difficult to physically install.

I need to be able to draw a schematic. The PIC will control the DPDT switches guided by a binary (PWM?) signal from the third channel in the RC system. The PIC will also have to react to whatever sensor interrupts (light for one and maybe touch in front) as well as generate steering and ESC signals when autonomous.

The RC racing will as original. Its speed and flexibility will not be compromised. Autonomous mobility can be slower. It is still part of the race, but speed will be less important than good programming.

It would be nice to program the autonomous actions with a simple language like LOGO or ROBOlab or whatever is used for VEX. I have not the faintest idea how to accomplish that without direct help from one of those organizations.

Little by little with you guys help==>
