I read the posts and I don't fully understand what you are doing. I get the perception that you want a computer somewhere in the building and the robots f in the hall.

The last time I did this, I put a laptop on the robot, used a free timelife giveaway usb camera, a power wheels 6 wheeler, a car battery ,ran Libranet with apache, and wrote CGI in c to control the 225in/oz steppers I was using to move it.

The stepper driver kept the motors constantly hot so battery life was low.

The forward, backward, etc, etc scripts were called when a button on the web page was clicked.

The robot was a simple build and worked easily from inside the school, getting through the school firewall waws a lot harder.

I probbably have the c cgi source as well as the web pages used, and maybe some documentation. If you want I can take a look and send it along to you.

For a while I had a telerobotic tethered turtle in my office which anyone in school could access. Turns out there are two kinds of people. The kind that spin the telerobotic turtle around 5000 times to wrap up it's teather and the kind that would drive it into you.
