I'm sorry Sherene.  I don't have any answers, just to say that our robot is
doing weird things at times too.  Like we will run a certain program and
then it just starts skipping steps that are in the program, for seemingly no
reason.  It will do that three or four times, then suddenly start working
again.  I have no idea.  We are getting it to work most of the time though.
 It sounds like what you are going through is really frustrating!  I would
encourage you to not pull the plug on your team competing though.  That
seems unfair to them with all their hard work.  The robot game is only 25%
of their total score.  They will still be able to talk to the judges about
their robot design and programming, even if their robot does nothing on the
actual table.  And they will give their presentation, and show their
teamwork!  Good luck, and I hope someone can answer here!
