     you used a drill and drill bit to make holes for bolts to go
     through.
     we drilled through the arduino into the deck.

-**** drilling
-     1. what would happen if you used a larger drill bit than the one
-       you used for drilling holes for the arduino?
-     2. why did we use a drill bit that was wider than the body of the
-        bolt used to hold the arduino?
-     3. why do people use drill bits that are smaller or the same size as
-        existing holes in circuit boards, like the holes in the blue
-        arduino?
-     4. why did we drill through the arduino, rather than marking holes
-        and using the drill to make holes where the marks were?
-     5. how does the drill hold onto the drill bit?
-     6. what would happen if the drill bit teeth were not flat on the
-        drill bit?
-     7. how can you break the drill bit when drilling?
-     8. should we drill at full speed?
-        why or why not?
-**** bolts
-     1. the bolts used to attach the arduino are 6-32 bolts.

+*** motor
+    these questions are about attaching the motor to the deck.
+    to attach the motor to the deck, first we attached motor mounts.
+    the motor mounts are the square things with 6 holes of
+    various sizes.
+    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?

-     2. if you see a bolt described as =4-40x1.25=" how long is it?
-     3. on a =4-40= bolt, how many times does the thread wrap around
-        one inch of the body?
-        4 times?
-        40 times?
-        1. how many times does the thread of a =4-40= bolt wrap around
-           two inches of the body?
-           8 times?
-           40 times?
-           80 times?
-     4. what part of the screw does the screw driver go into?
-**** part placement
-     1. name some reasons for the arduinos placement on the deck.

-        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?
-**** misc.
-     1. should you pick up a battery by the wires coming out of it?
-     2. what are the wires coming out of the battery called?
-     3. what's the difference between stranded and solid core wire?
-     4. why are we using solid core wire for plugging into
-        the breadboard?
-     5. why do we put the glue dots on the side of the battery pack
-        without the on/off switch?
-     6. why do we wrap tape around the body of the motors?
-     7. why do we put a zip tie around the motor?
-     8. do you have a ratcheting socket wrench?
-        what is a ratcheting socket wrench?
-     9. what would happen if there were no caster on the back
-        of the robot?
-     10. what is the robot tread made out of?
-     11. why is it difficult to push the sonar into the sonar holder?
-     12. what would happen if the sonar were easy to push into the sonar
-         holder?

+*** breadboard
+    the breadboard is the white thing in the middle of the deck.
+    it has a black thing plugged into it.
+    almost everything with wires plugs into the breadboard.
+    1. where is the breadboard?
+    2. what's the difference between stranded and solid core wire?
+    3. why are we using solid core wire for plugging into
+       the breadboard?
+    4. should the black chip (motor controller) be on the left or the right
+    5. why should the chip be on the right?
+*** batteries
+    there are two battery packs on the robot.
+    one of them powers the motors, and is in the clear battery pack.
+    the black battery pack powers the arduino.
+    1. why are the battery packs between the wheels and caster
+       (roughly)?
+    2. should you pick up a battery by the wires coming out of it?
+    3. what are the wires coming out of the battery called?
+*** caster
+    the caster is the solid metal sphere.
+    it is held in a 3d printed plastic housing called the caster standoff.
+    the standoff is fixed to the deck with 3 nuts and bolts.
+    1. where is the caster?
+    2. why is the caster in the middle of the back, instead of on the
+       left or right?
+    3. why do we put the glue dots on the side of the battery pack
+       without the on/off switch?
