Motivate Discussion
Q: Ask the students what they think would happen if they added a stop driving block to
their project. (Have them record their answers in their engineering notebooks).
A: With this project, the robot would not move at all. This is because the project is telling the
robot to drive forward, but then it is immediately telling it to stop. This happens so quickly that
the robot does not move.
If students did answer that Autopilot would move forward and then stop, the students could
then be asked how far the robot would move forward before it stopped. This could lead into
the discussion that the project moves very quickly through the commands and eventually
lead the students to realize that because the project does move so quickly through the
commands that the robot does not move.
The discussion could then be a good introduction to the use of the wait block:
