Chapter 7, Drive and Turn - Moving Motors with Python

• Why do we use the atexit.register mechanism?
  • To register a stop function, so the robot's motors will stop when the code stops, even if there is an error
• How can we correct a motor going the wrong way?
  • We can swap the two motor-lead connections for that motor at the screw terminals.
• What are the main advantages of a common interface for a Robot object?
  • We can build new behaviors on top of the object without writing setup and translation code repeatedly.
  • We can move our behaviors onto other motor controllers by wrapping them in the same interface.
• How must the motors move (left and right) to make this robot turn?
  • To turn, one motor must be going at a different speed from the other. ...
