anyone have any suggestions on a low cost method to send the user

(maybe a CAT5 cable)?

make the cat5 a crossover

put a mini ITX motherboard on your robot

have a laptop computer at the other end of the cable.

run a video server on the bot.

That is an interesting idea. But a little more expensive than I was
thinking of.

It's far cheaper than the alternatives you are talking about.

Used pentium II laptop: $50 on eBay

Mini-ITX board: $100

Webcam: $40

I do understand how the laptop would save me money by not having to
use the case and all of the mechanical pots., switches, also it would
have a screen already.
It would be pretty compact also.

But I am wanting to make more than just one of these robots. So,
hoping on good laptop prices on E-bay isn't going to help me with
this.
Also, I want the system to be more robust and be able to withstand a
little abuse. I don't know how many drops a laptop might take.

The communication between the robot and operator panel I was hoping to
base on a couple inexpensive ICs.

Thanks for your ideas. It gives me something to chew on.
