Performance objectives

• Explain the role of the controller as the 'brain' of a robot.
• Identify mechanical parts like motors, grippers, and wheels.
• Understand how sensors provide data to a robot.
• Describe real-life examples of how sensors are used.
• Analyze the impact of robotics in Ghana.

Lesson summary

This lesson introduces the exciting world of robotics. We will explore the fundamental principles that make robots work. We often see robots in movies, but they are also becoming very important in real life here in Ghana and around the world. From the traffic lights that control cars in our cities to the machines that help package fufu powder in factories, the principles of robotics are everywhere. Understanding how robots "sense," "think," and "act" helps us understand the technology that is shaping our future in agriculture, healthcare, and industry.

Lesson notes

The operation of any robot can be broken down into three simple principles, which we can compare to how a human being works: Sense, Think, and Act. SENSE (Input): The Robot's Senses THINK (Process): The Robot's Brain ACT (Output): The Robot's Muscles

Let's break down each part. Part 1: SENSE - Using Sensors to Gather Information

Just like humans use their five senses (sight, hearing, touch, smell, taste) to understand the world, robots use sensors. A sensor is a device that detects or measures a physical property and records, indicates, or otherwise responds to it. What they do: Sensors convert physical information (like light or heat) into an electrical signal that the robot's brain can understand.

Here are some common types of sensors:

Evaluation guide

• Explain the controller as the “brain” of the robot.
• Demonstrate understanding of mechanical parts such as motors, pistons, grippers,
• wheels and gears that make the robot move, grab, turn around or lift
• (Actuators).
