What is Robotics? Exploring the World of Robots
Students will learn about different types of robots and their applications in various fields.
What you'll learn
- Identify and classify at least three different types of robots (e.g., industrial, medical, exploratory) based on their function and design with 80% accuracy.
- Explain the basic components of a robot (sensors, actuators, controller, power source) and their roles in enabling robot functionality, using a diagram with at least 4 labeled parts.
- Apply the concept of algorithms by creating a flowchart or pseudocode to describe a simple task a robot could perform, such as navigating a maze or picking up an object.
- Compare and contrast the advantages and disadvantages of using robots in at least two different real-world applications (e.g., manufacturing vs. surgery), justifying their reasoning with specific examples.

Introduction & Learning Objectives
Learning Objectives
Define 'robot', 'sensor', 'actuator', and 'program'.
Identify the three main parts of a robot: sensors, controller, and actuators.
Write a simple program using text-based code to make a robot move forward and turn.
Use a variable to store a value, like speed or distance, in a robot program.
Explain how a sensor (like a touch or distance sensor) can provide input to a robot's program.
Create a simple sequence of commands to make a robot navigate a small obstacle.
Debug a simple robot program by identifying and correcting errors in the code.

Key Concepts & Vocabulary
TermDefinitionExample
RobotA machine that can be programmed to carry out a series of actions automatically.A robot vacuum that cleans your floor on its own following a programmed path.
SensorA device that detects or measures something in the environment and sends information to the robot's brain.The 'eyes' of a robot, like a distance sensor that tells the robot how far away a wall is.
ActuatorThe part of a robot that allows it to move or interact with its environment, like a motor or a gripper.The wheels on a robot that make it drive, or an arm that can pick something up.
ControllerThe 'brain' of the robot that processes information from sensors and sends commands to the actuators.A small computer chip on the robot that runs the program you write.
ProgramA set of...

Core Syntax & Patterns
Command with Parentheses
commandName();
Use this to tell the robot to perform a specific action. The name of the command describes the action, and the parentheses `()` are required to run it. For example, `moveForward();` tells the robot to start moving forward.
Command with Parameters
commandName(parameter);
Use this to give a command more specific information. The value inside the parentheses is called a parameter. For example, `wait(1000);` tells the robot to wait for a specific amount of time (1000 milliseconds).
Variable Assignment
variableName = value;
Use this to store a piece of information in a variable. The `=` sign assigns the value on the right to the variable on the left. For example, `motorSpeed = 75;` stores the number 75 in the `motorSpeed` variable....

Challenging
You are designing a robot to automatically sort a pile of mixed red and blue blocks into two separate bins. What combination of components is absolutely essential for this robot to work?
A.touch sensor and a speaker
B.Two distance sensors and an LED light
C.sound sensor and a servo motor
D.color sensor, a gripper (actuator), and motors for movement
Challenging
A robot's program uses a variable `batteryLevel`. The robot must return to its charging station if `batteryLevel` drops below 20. This check needs to happen constantly while the robot is operating. Where is the best place in the program's structure to put the `if (batteryLevel < 20)` check?
A.Inside the main, repeating loop of the program
B.At the very beginning of the program, before the main loop starts
C.At the very end of the program, after the main loop has finished
D.Only inside the function that controls the wheels
Challenging
A robot is programmed with `speed = 75;`. A few lines later, the code says `speed = 50;`. After both lines have run, the command `moveForward(speed);` is executed. What speed will the robot use?
A.It will use the speed of 75
B.It will use the speed of 50
C.It will use an average speed of 62.5
D.The code will have an error because the variable was defined twice
