Note:
In programming, flag bits distinguish various states in order to make the robot execute different commands.
(1) Objective: Returns “True” when two values are not equal; otherwise, “False” is returned
(2) Returned Value: Boolean
(3) Example: Indicate successful identification of one person
If no person or multiple people appear in the robot's field of view, the “scanning” sound effect will play; if
exactly one person is identified, however, the “identified successfully” sound will play.
