I'm working with my son to build a Mars rover for a school project. We are trying to setup a mindstorms rover w wireless X10 camera remotely controlled via the IR tower by some simple forward/back/left/right buttons on a PC app or browser.

I thought that Web Brick was going to do the trick (http://popbubble.com/Lego/WebBrick/) but it seems incompatible w XP. Any other low/no programming required ideas?

Thanks! Chris Curran

I created a rig for my webcamera such that it can be rotated and tilted.
I managed to control it from a PC, via the IR tower, using Java.

To do this I had to install a Java VM on the lego brick (http://lejos.sourceforge.net/).
Once you've got that working you can use the rcxcomm packages to communicate between a Java app on your PC and the lego brick.

I managed to get this to work fine under XP. If you want to be able to control it from a web interface you should be able to use a webserver running server-side Java (JSP/servlets) to send & receive messages. I haven't tried this, but I think you can use applets to communicate asynchronously with Java on a webserver so you can put some buttons on a web page to control it.

Let me know how you get on.
