Here is an example...
Let's say that I am at work, and I leave the robot on all day. Now when I
come home do I want to watch 12 hours of recorded video? I think not... Your
"eyes" wouldn't be closed, you just wouldn't be remembering what you saw,
unless it met certain criteria.
You could do this on the RCX side, the computer side, or both. For example
from the robot side, lets say the robot is sitting stationary and detects
movement using the Infrared transmitter as a motion detector. This would be
grounds to tell the computer to record what it is seeing. On the computer
side, the bot could move to one of several security look-out points and
signal the computer that it is in position. You could then take a reference
frame, and use that to determine if something in the scene has changed and,
if it has, start recording....
Do you see where I am going with this? I would like to just see the
interesting parts of a robots day. I am assuming that the "interesting
parts" would contain movement of some type.
I'm not sure what kind of lag you would encounter while all of these
decisions are being made. If it turns out interesting stuff is getting cut
off at the beginning, a buffer could be used to compensate.
