hmm. I was thinking it could push a cruse ship, which is the size of the empire
state building...

My mom and my wife both bought me LEGO sets for X-mas. But there was nothing as
fun as a Bionicle set.

I doubt it can hurt your robot. :)

so, what do you do if you have an "issue"?
I have a couple suggestions for overall programming. Given that the lighting
conditions at the event are not known (at this time) it may be hard to predict
if "empty" will be higher or lower than "black" and/or "red".
I'd suggest creating a range of values for both black and red, and put them in
#define statements at the beginning of your program.
Like:
#define black_min 30
#define black_max 32
#define red_min 40
#define red_max 42
Then make sure all your checks use these constants.
And, (if it were me) I'd just take about 10 readings and average them. I would
expect "empty" readings to be all over the place, and "black" or "red" to be
pretty constant.
But that's just me.
