1. the Vision Command Camera and writing software for the camera
2. interfacing your software with a legOS powered robot.
1.
The Lego Vision Command is actually a Logitech USB camera repackaged inside
some lego pieces.
There is a [mostly inactive] newsgroup for this
lugnet.robotics.vc
Unfortunately, most of the information you'll find there is out of date.
After some more digging, you will find that Logitech released an SDK for its
QuickCams, a boon for anybody wanting to write software for the Vision
Command Camera.
I highly recommend looking at what Paul Oh did last year. We used this web
page as a reference to do some vision projects, and were highly successful.

To do this, you will need Visual C++ 6.0
2.
So keep in mind that the RCX is not nearly powerful enough to do any sort of
real-time processing. That, and it doesn't have a USB port. So
communicating with the RCX and getting it to do what you want becomes a
matter of including some LNP commands in your image processing code, so that
it instructs the robot to do whatever it wants.
I hacked up some of the legOS source files to make a half-implementation* of
LNP for windows. I don't like WinLNP because that's really bulky and
confusing. You can get the two C++ files for this at
http://www.cs.brown.edu/~ashuang/misc/lnp_host_win32.cpp
http://www.cs.brown.edu/~ashuang/misc/lnp_host_win32.h
good luck,
Albert
*I say half-implementation because in this version, I didn't implement any
listening procedures for LNP. You can send via the logical and the
addressing layer, but no listening.
