Welcome, future engineers and programmers! In our last lessons, we learned how to plan a robot's actions using flowcharts. Today, we will bring those plans to life. We will learn how to translate complex decisions from a flowchart into a real computer program that a robot can understand and execute. This skill is crucial because modern technology, from the Mobile Money (MoMo) system on your phone to automated irrigation systems on farms, relies on making a series of decisions one after another. This is called "nested decision-making," and by the end of this lesson, you will be able to program it yourself.
A. Recap: Simple Decisions (if-else)
Remember that a robot makes decisions using conditions. We use the diamond shape (♦) in a flowchart to represent a question or a condition. In programming, this is handled by an `if-else` statement. `if`: Checks if a condition is true. If it is, it performs an action. `else`: If the condition is false, it performs a different action.
Example: A simple robot cleaner. Flowchart Condition: Is the battery level below 20%? Program Logic: `if` battery is less than 20%, `then` go to the charging station. `else` (meaning the battery is 20% or more), `then` continue cleaning. B. Main Concept: Nested Decisions
A nested decision is a decision made *inside* another decision. It's like asking a follow-up question. You only ask the second question if you get a specific answer to the first one.
