This lesson introduces learners to the exciting world of robotics. We will explore what robots are and the many ways they are changing our world, from factories and hospitals to farms and even our homes. Understanding robotics is important because these machines are becoming more common in Ghana and around the world, creating new jobs and solving difficult problems. We will look at real-life examples, including some right here in Ghana, to see the good things (prospects) and the difficult things (challenges) that come with using robots.
This section breaks down the essential information learners need to understand the topic. A. What is a Robot?
Many people think of robots as walking, talking machines from movies, like Transformers or Wall-E. While some robots look like humans (humanoids), most do not.
A simple and accurate definition is: A robot is a machine that can be programmed to automatically carry out a series of complex actions.
A good way to understand how they work is the "Sense-Think-Act" cycle: Sense: Robots have sensors to gather information about their environment. This is like our five senses (sight, hearing, touch, etc.). A robot's sensors can be cameras, microphones, temperature sensors, or motion detectors. Think: Robots have a computer or a processor inside them, which acts as their brain. This processor uses the information from the sensors to make a decision based on its programming. Act: Based on the decision, the robot performs a physical action using its actuators. These are the parts that move, like motors, grippers, wheels, or robotic arms.
