Sorry, two different approaches. The first approach I tried used the ACGI

do JavaScript "window.location.reload()" in front document

Grace, you apppear to be using an applescript to control the browser's
refresh function? Is that to renew the controller or to update the camera
image? If you explain why this is part of the picture, I think we might
'get it' better.
If the camera is delivering a streamed video, I'd suggest using a
frameset, placing the camera view in one frame and the robot controller in
another. Think of the controller as providing one command at a time. Each
time the user clicks a command or hits submit in the controller frame, the
browser, as has outlined, sends that info to the server, which passes it
to the acgi, which does the thing and returns a new form (or a redirect to
a form) to the browser, which updates the display in the controller frame.
As for reloading, you don't really want to use an HTTP or a META-tag
refresh (for example) in the controller frame because that will fire even
if a visitor is in the process of filling out the form. But you might use
a refresh in the "viewer" frame if your camera only delivers stills on
command rather than streamed video.
The scenario described here (and by has) uses a browser as a means of
seeing and controlling the robot, but the browser is not scripted directly
by AS. It may receive JS content from your web site, and you may generate
the JS from an AS acgi on the web site, but from the browser's point of
view, all it sees is normal web content.
HTH.
