• Robot's brain and programming applications, which is where to start the adventure with LEGO robots
• Engines and sensors, or how to ensure proper robot operation in the real world
• My own robot, or how to build and program a robot depending on the needs

Robotics is one of the rapidly growing areas in the modern world. Robots work well in a wide variety of conditions, and the ability to program them is more and more appreciated on the job market. That's all true, but you can not forget that programming robots can also be great fun. Especially if it concerns LEGO MINDSTORMS robots! You do not have to be a child to feel the excitement associated with the independent design of the behavior of the robot that will perform all the activities required from him. So - do it!

In this book you will find all the elements necessary to start working with LEGO MINDSTORMS. The author will show you how the EV3 cube works and what applications you can use to program your robots. Will lead you through the land of numerical data, logical operations, arithmetic and other, as well as control instructions. You will be familiar with the possibilities of creating subroutines and multithreaded programming . Thanks to it, you will get to know the motors and sensors and the blocks used to program them. You will see how you can combine EV3 cubes, and then look at the author's three favorite robots. This will surely inspire you to come up with your own LEGO designs and software that controls them!
