I thought my original question was fairly clear, but I guess not! I want to
program some "random" behaviors for my robot and download them into the RCX.
This being the case, I assume that I need to use the "random" register in the
RCX, as opposed to generating one inside VB.
Specifically, I want to program the robot to, for example, turn it's head
left and then right "X" times, where X = a random number between 1 and 5.
At other times, I'd like to tell the robot to go into "explore" mode for
anywhere from 10 to 250 seconds.
What is the best way to do this using SPIRIT.OCX commands?
Also, if anyone has any commented source code (for the Mindstorms RCX) I'd
love to see it!
Thanks for the replies.
