Apparently it only works with the Lego cam. Using any other camera (USB or
not) will
not work as several people here tried it already. I have both the lego
camera and the XCam2.
XCam2 is great as long as you have plenty of light! Otherwise, the image is
dark. Whenever I
need a TRUE mobile robot, I use the XCam2 with my ATI All-in-Wonder video
card which has
a built-in framegrabber. For all my other SEMI mobile robots (where I am
stressing lego purity),
I use the Lego Cam...
Cheers,
Ram

| I think I didn't mention that there is an addition for XCam2 called XRay which makes XCam2 a usb webcam. My question was if it could be used. Can you select which camera you would like to use in VC software or does it only work with the LEGO cam? (...) (24 years ago, 8-Jan-01, to lugnet.robotics.rcx)
