Decision-Making: Using Conditional Statements to Control the Robot's Behavior

Learning Objectives Define what a conditional statement is and why it's used in robotics. Explain the purpose of `if`, `else`, and `else if` keywords. Write a simple `if` statement to make a robot perform an action based on a sensor reading. Construct an `if-else` statement to give a robot two different choices of action. Use comparison operators (like <, >, ==) to create a true/false question for the robot. Trace the logic of a simple program to predict a robot's behavior. Have you ever wondered how a robot vacuum avoids bumping into walls or falling down stairs? 🤔 It's all about making smart choices! In this lesson, you'll learn how to give your robot a 'brain' using conditional statements. These are special instructions that let your...

TermDefinitionExample Conditional StatementA command in programming that performs different actions depending on whether a condition is true or false. It's like asking a 'yes' or 'no' question.`IF` the distance sensor sees an object less than 10 cm away, `THEN` stop the motors. ConditionThe 'question' part of a conditional statement that can only be answered with true or false.`distance < 10` is a condition. It's either true (the distance is less than 10) or false (it's not). BooleanA data type that has only two possible values: `True` or `False`. Conditions always result in a Boolean value.The statement `5 > 3` is `True`. The statement `light_sensor_value == 'dark'` could be `False`. Comparison OperatorsSymbols used to compare...

The `if` Statement Structure if condition: # Code to run if condition is True Use this when you want the robot to do something special, but only in one specific situation. If the situation isn't happening (the condition is false), the robot just skips those instructions. The `if-else` Statement Structure if condition: # Code to run if condition is True else: # Code to run if condition is False Use this when your robot has to make a choice between two different actions. It will always do one or the other, never both and never neither. The `if-else if-else` Statement Structure if condition_A: # Code for condition A elif condition_B: # Code for condition B else: # Code for all other cases Use this when your robot needs to check multiple cond...
