-   what follows is a high level description of the contents of the most
-   important top level directories in the class content.
-*** 3d-printables
-    the parts of the robot that are 3d-printed are in this directory.
-    use openscad to open the parts in this directory.
-*** build-stages
-    all the wiring diagrams and arduino code live in this directory.

-    under this directory, there is one subdirectory for each

-    each build stage is prefixed with a letter to make it appear in
-    order.
-    for example, =a_serial= contains the first build stage.
-** troubleshooting
-    to troubleshoot a misbehaving robot, go through these stages
-    in order until you find a stage that does not work correctly.

-    first, in =a_serial=, you'll check whether the arduino can
-    communicate over the serial connection with the computer.

-    in each stage, make sure the wires shown in the fritzing
-    diagram are correctly connected on your robot.
-    then load the corresponding arduino sketch to your robot
-    and either check the serial monitor, or turn on the motor battery.
