I will try to answer your questions here:
Andrew- ROBOLAB is a great program. NQC is also a great program. I have
used them both. It depends on which you prefer. In my case, I do not use
(say) C++ elsewhere and I find ROBOLAB easier to remember, that is, I don't
forget how to do it between projects. Also, it seems to be in the spirit of
LEGO, (fitting blocks together).
Serge- I bought Vision Command for the parts, with hopes of using the
camera as a sensor in a future project. But it does have a built-in
microphone on a dandy long 5m USB cable and the high background actually
enhances 'machinery noise'. So I'm not disappointed.
Jean-Philippe- If you want a compact good-looking movie, buy QuickTime Pro.
It lets you take a series of still images (jpegs) and turn them into a movie
at whatever frame-rate you want. You can splice in a sound-track. For LEGO
machines, 6 fps is adequate. My digital camera, a Nikon 950, has a setting
that, when you hold down the button, will take VHS (640 x 480) images at 1/2
sec intervals. Why that should look realistic at 6 fps... is a mystery to
me... but it does. All of this is made easier with Thumbs Plus software
from Cerious Software, www.cerious.com. They have a wizard that lets you
batch-process hundreds of frames in one operation. Typically: Increase
brightness by 30% and resample to 320 x 240. The entire subdirectory is
done in seconds.
Robert- You need lots of light to drive the lense-opening small and the
exposure high. I recommend a 500 w halogen construction lamp, much cheaper
than a fancy photo-flood equipment. LEGO machines don't require careful
color-balance and shadow control, they need lots of light.
Thanks again to everyone for your nice notes!
Jerry
