Day Four: We're Following the Leader...or the Line.

Today's challenge involved teaching our sciborg, John Silver, how to follow the line.  Let's say that he didn't take to this idea.  We struggled for a whole class, trying to get John to notice the line, which involved much beeping/chirping and circular motion.  John did not want to be obediant.

We were confused as to why our program was not working as we desired.  We tried roughly three different ideas, with multiple substitutions within each idea, trying to find the perfect plan, but none of the ideas worked.  John Silver just wanted to play ring-around-the-rosie, by himself.  Here is the version we finally did get to work after much work.

We realized towards the end of class, that John's disobediance may have resulted in part because two wires were not cut down and so touched each other.  Not a good thing.

These two should NOT be touching.




So second day, we fixed our wires and now the program would run.  John would obediently follow a black line marked on a white surface.  All is good.
