Robotics Introduction
Discover how robots work and how they think. Learn what makes a machine a robot, meet its core parts (sensors, actuators, and a controller), and write the kind of sense-think-act logic robots run, right in your browser. Beginner friendly, no hardware needed to start.
What you’ll learn
- Explain what makes a machine a robot: sense, think, act
- Identify the core parts: sensors, actuators, and a controller
- Understand how a microcontroller runs a robot in a loop
- Turn a sensor reading into an action with simple control logic
- Plan your own first robot build around one sensor and one action

What is Robotics · Lesson 1 of 11
Welcome to robotics
Welcome
A robot is a machine that can sense the world, make a decision, and act on it, on its own. From factory arms to delivery drones to a line-following toy car, every robot does the same three things: sense, think, act.
Robotics brings together electronics, mechanics, and code. In this course you will learn how robots are built and how they think, and you will even write and run the kind of logic a robot uses, right in your browser. No hardware needed to start.
By the end you will understand:
- What makes something a robot
- The main parts: sensors, actuators, and a controller
- How a robot turns a sensor reading into an action
- How to plan your own first build
Practice
Look around you. Name two machines that sense and react on their own, for example an automatic tap or a phone that rotates its screen. What does each one sense, and what does it do in response?
