     through.
     we drilled through the arduino into the deck.

 **** bolts
-    1. the bolts used to attach the arduino are 6-32 bolts.

        the bolts used to attach the motor to the motor mount are
        4-40 bolts.
        Are the 4-40 bolts fatter or thinner than the 6-32?

 **** part placement
-    1. name some reasons for the arduinos placement on the deck.
-       1. could it have been placed diagonally?  why or why not?
-       2. could it have been placed in any other location? why or why not?
-       3. could it be upside-down?  why or why not?
-    2. why are the motors between the wheels?
-    3. why are the motors pointed towards the caster in the back?
-    4. why are the battery packs between the wheels and caster
-       (roughly)?
-    5. where is the breadboard?
-    6. where is the caster?
-    7. why is the caster in the middle of the back, instead of on the
-       left or right?
-    8. should the black chip (motor controller) be on the left or the right
-    9. why should the chip be on the right?
