Depending on how you install the motor mounts to each motor will dictate how the motor can be installed on the
base plate.
Note: Do not worry about the motor orientation as you will determine proper motor operation in
how you connect the motor leads to the SparkFun Serial Controlled Motor Driver.
Notice how in the picture
below one motor has the label facing up, while the other has the label facing down.
Place the other circular robot chassis plate on top of and align the two "+" and the motor mount tab recesses. Hold
the sandwiched chassis together with one hand and install the remaining Phillips head screws included with the
Circular Robotics Chassis Kit through the top plate & into the threaded standoffs.
Your main chassis is now assembled! The Circular Robotics Chassis Kit also contains a very small caster wheel
assembly, but we have included a larger metal caster ball to increase the stability of the SparkFun Jetbot. We will
cover the installation of this caster ball later in the tutorial.
Utilize three of the included 1/4 in 4-40 Phillips Screws through the top chassis plate with threads facing up &
install the 2-3/8 in #4-40 Aluminum Hex Standoff until they are finger tight.
