John,
My thought was that my light detector would be on the front of my car. The servo searching capability could be done by steering right and left just a little bit. This way the car goes directly to the light.

I imagine that once it gets there, the student operating he RC transmitter will be able to see it and retake control. These things go way fast under RC control. I image it creeps when autonomous.

Make sense to you?

I am having a difficult time figuring out what Basic Stamp starter kit is the best for me. I am USB oriented. I am guessing that I should spring for the 160 bucks for the BASIC Stamp Discovery Kit - Serial (With USB Adapter and Cable)

Your thoughts please. I'm going to bed now. It is eleven o'clock out east.

Ken
