Lesson 1: What is a Robot? Defining Autonomous Machines

Learning Objectives Define the term 'robot' using the Sense-Think-Act cycle. Identify the three core components of a robot: sensors, a controller, and actuators. Differentiate between an autonomous machine and a remote-controlled device. Explain how a robot uses a program (a set of instructions) to make decisions. Analyze a given machine and determine if it qualifies as a robot based on a set of criteria. Provide at least three examples of robots in the real world and describe their functions. Is your family's robot vacuum cleaner truly a robot? What about a remote-controlled car? 🤖 Let's investigate what makes a machine autonomous! In this lesson, we will uncover the true definition of a robot. We'll learn the three essential parts all robots shar...

TermDefinitionExample RobotA machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer.A robot vacuum cleaner that navigates a room, avoids obstacles, and cleans the floor without human control. AutonomousHaving the freedom to act independently. For a machine, it means making decisions and performing actions without direct human control.A self-driving car stopping at a red light on its own is acting autonomously. SensorA device that allows a robot to perceive its environment. It's like the robot's senses (sight, hearing, touch).The bump sensor on a robot vacuum tells it when it has hit a wall. ControllerThe 'brain' of the robot. It's a computer that processes information from sensors and runs a program to...

The Sense-Think-Act Cycle Sense -> Think -> Act This is the fundamental pattern of how an autonomous robot operates. Use this cycle to test if a machine is a robot. It must perform all three steps on its own to be considered autonomous. Rule 1: Sense The machine must use sensors to gather information about its environment. Does the machine have a way to 'see', 'hear', or 'feel' what's happening around it? Examples: cameras, microphones, touch sensors, distance sensors. Rule 2: Think The machine must use a controller (a computer) to process sensor data and make a decision based on its program. Does the machine make a choice without a human pressing a button for every action? This is where programming and control structures like...
