Well, it looks like in the 11th hour I'm going to have to abandon my
differential drive for Project Y....there is WAY too much play in the
differential gear train, which makes tracking the light with the whole
bot virtually impossible...

Guess tonight I'll gut it and replace it with a boring old A/B drive.
Good thing I coded so all I should have to change is some drive declares
and some tuning parameters :)
GRRRR.
If that doesn't work it might be time for a last minute rebuild (nothing
like a cram session).
