Robotics is a fascinating field that is gaining importance in the recent decades. Robots have so far been controlled through a pre-programmed way and also through sensor based feedback. In this book, I have focused on controlling robots through a computer via a microprocessor. Moreover, you can make these robots at your home. There are six projects in this book that teaches you how to build various aspects of a robot. By doing these six projects, you will get confidence to build robotic projects that have graphical user interface with it. It took nearly 1 year for me to conclude that Processing IDE can be used as a good graphical user interface for robots. Back in the year 2018, I started building my own robots using Processing IDE as my graphical user interface. I have build manipulators and mobile robots using it. In this book, I am sharing a few of my projects that seemed to be interesting for people around the world. I posted my videos of the robots with GUI on the YouTube and I received E-Mails from countries like China, France, Turkey and India. These mails were regarding the code that I have used for making the robot. Hence, I have decided to write a book that would help people build their own computer controlled robots at their desktop. My vision is to make people build their own computer controlled robots at their home and use it in their day-to-day life. I hope my vision comes true by 2030! -Rajashekhar V S
