Robotics crash course: Robotics 101

Robotics 101: Build Your First Robot

Have you ever been captivated by robots in movies, or wondered how those amazing machines are used in a variety of fields, from fighting fires with the Kerala fire force to exploring space with NASA, and even creating a humanoid robot named Sophia that can talk like a human? If you’re a complete beginner interested in exploring the world of robotics, you’ve come to the right place! This crash course is designed specifically for you.

By the end of this crash course, you’ll gain a solid understanding of the fundamentals of robotics. You’ll learn what robots are, how they work, and the incredible things they can do. More importantly, you’ll discover if the exciting field of robotics sparks your passion and holds potential for your future! Forget the complicated terms for now! This crash course is your first step towards the fascinating world of robots. We’ll break down the concepts into easy-to-understand explanations, so you can grasp the essence of robotics.


What are Robots and How Do They Work?

Robotics is the branch of engineering that deals with the science, designing and manufacturing of robots. But what exactly is a robot? Think of it as a machine that can sense its environment (like seeing with a camera), process information (like a mini-computer in its head), and take action (like moving its arms or wheels). While robots come in all shapes and sizes, they share some fundamental components that work together to bring them to life. Think of these components like the organs in a human body, each playing a crucial role. 
We’ll focus on the key parts without getting too technical:
  1. The Body(Mechanics): This is the robot’s physical structure, its arms, legs, or whatever form it takes to interact with the world.
  2. The Senses(Sensors): Just like us, robots need to perceive their surroundings. Cameras, LiDAR (like radar but with light), and touch sensors are some ways robots “see” and gather information.
  3. The Movers(Actuators): These are the robot’s “muscles,” motors that allow it to move and manipulate objects.
  4. The Brain(Control System): The control system is the robot’s brain, processing information from the sensors and sending instructions to the movers, telling the robot what to do.
  5. The Power Source: Every robot needs energy to operate, whether it’s a battery, solar power, or something else.
By working together, these components allow robots to perform amazing tasks with precision and speed. Now, imagine these robots performing surgery, assembling cars, or even cleaning your house! The possibilities are truly endless.

See Robotics in Action: Hands-on Project with Wokwi Simulator


Learning by doing is a key to unlocking new concepts. In this crash course, we’ll take you on a fun and engaging journey with a hands-on project using the free Wokwi online simulator. Get ready to build your very first robot – virtually! We’ll guide you through creating a blinking LED circuit, a fundamental building block in many robotics projects.

In this project, you’ll use Wokwi to build a virtual circuit with an LED (light-emitting diode) and an Arduino board (a popular microcontroller platform for robotics). We’ll provide a clear image of the circuit diagram, so you can see how the components are connected. You’ll also learn some basic Arduino code, the language used to give instructions to your robot. By tweaking the code, you’ll control the timing of the LED, making it blink on and off at specific intervals.

This interactive project is your chance to experience the magic of programming a robot, even without any physical components in hand. As your LED blinks to life, you’ll gain a practical understanding of fundamental robotics concepts like programming, circuits, and robot control. It’s a small step with a big impact, potentially igniting a passion for robotics that could propel you further.
