Course Overview

Before diving into the projects, let's take a look at the course overview to understand what you'll be learning and the skills you'll acquire.

Skills you'll acquire:

  • Understanding of C++ programming language
  • Familiarity with robotics concepts and principles
  • Hands-on experience in coding and building robots

Course duration: Approximately 8-12 weeks

Prerequisites: Basic programming knowledge (preferably in C++), understanding of robotics concepts, and familiarity with basic electronic components.

C++ Basics

In this section, we'll cover the basics of C++ programming to ensure a solid foundation for your robotics projects. Topics include:

  • Variables and data types
  • Control structures (if-else statements, switch-case)
  • Loops (for, while, do-while)
  • Functions and function overloading
  • Pointers and memory management

By mastering these fundamentals, you'll be equipped with the necessary skills to tackle more complex robotics projects.

Conditional Statements and Loops

Conditional statements and loops are essential concepts in programming. In the context of robotics, they allow you to make decisions and control the behavior of your robot. In this section, we'll explore:

  • If-else statements for making decisions based on conditions
  • Switch-case statements for handling multiple cases
  • For loops for iterating over a sequence of statements
  • While and do-while loops for repetitive tasks

Understanding and implementing these concepts will enable you to create more dynamic and intelligent robots.


Functions play a crucial role in modularizing your code and making it more organized and readable. In this section, we'll delve into:

  • Function declaration and definition
  • Parameters and return types
  • Function overloading for creating multiple functions with the same name but different parameters

By utilizing functions effectively, you'll be able to break down complex tasks into smaller, manageable components.

Arrays and Pointers

Arrays and pointers are powerful tools in C++ programming, particularly in robotics projects. In this section, we'll cover:

  • Arrays for storing and manipulating collections of data
  • Pointers for accessing and manipulating memory addresses
  • Dynamic memory allocation for efficient memory management

Understanding arrays and pointers will enable you to work with sensor data, control motors, and interact with external devices in your robotics projects.

C++ Classes

Classes are an integral part of object-oriented programming, and they play a significant role in robotics development. In this section, we'll explore:

  • Class declaration and definition
  • Member variables and member functions
  • Constructors and destructors
  • Inheritance and polymorphism

By utilizing classes effectively, you'll be able to create modular and reusable code for your robotics projects.


Now that you have a solid understanding of C++ programming and robotics concepts, it's time to put your skills to the test with a hands-on project. In this project, you'll design and build a line-following robot using C++ and basic electronic components. The project will involve:

  • Designing the robot's chassis and wiring the components
  • Implementing sensor readings and motor control
  • Programming the robot's behavior to follow a line

This project will provide you with practical experience in robotics programming and give you a tangible result to showcase your skills.

Course Summary

Congratulations on completing the C++ robotics projects course! Throughout the course, you've gained a solid understanding of C++ programming and its application in robotics. You've learned essential concepts such as conditional statements, loops, functions, arrays, pointers, and classes. By completing the hands-on project, you've demonstrated your ability to apply these concepts to build a functioning robot.

Remember, robotics is a vast field, and there's always more to learn and explore. Keep experimenting, building, and expanding your knowledge to unlock new possibilities in the world of robotics.
