Ideas in this flowchart

• A Python example implementing a basic distance-based decision rule
• The rule is implemented by the choose_action function
• The distance value is assumed to come from a working sensor driver
• The function evaluates the distance and selects an action
• Is distance_cm less than 20?
• If the condition is true, return STOP
• If the condition is false, return MOVE_FORWARD
• The example assigns distance the value 15
• The selected action is stored by calling choose_action(distance)
• The program prints the selected action
• Because 15 is less than 20, the expected output is STOP
