Smart Robotics with LEGO MINDSTORMS Robot Inventor

By: Aaron Maurer

Overview of this book

LEGO MINDSTORMS Robot Inventor is the latest addition to the LEGO MINDSTORMS theme. It features unique designs that you can use to build robots, and also enable you to perform activities using the robot inventor application. You'll begin by exploring the history of LEGO MINDSTORMS, and then delve into various elements of the Inventor kit. Moving on, you'll start working on different projects which will prepare you to build a variety of smart robots. The first robotic project involves designing a claw to grab objects, and helps you to explore how a smart robot is used in everyday life and in industry. The second project revolves around building a working guitar that can be played and modified to meet the needs of the user. As you advance, you'll explore the concept of biomimicry as you discover how to build a scorpion robot. In addition to this, you'll also work on a classic robotic challenge by building a sumobot. Throughout the book, you'll come across a variety of projects that will provide you with hands-on experience in building creative robots, such as building a Dragster, Egg Decorator, and Plankton from Spongebob Squarepants. By the end of this LEGO book, you'll have got to grips with the concepts behind building a robot, and also found creative ways to integrate them using the application based on your creative insights and ideas.

Writing the code

The code for this project needs to solve a few key issues when it comes to sumobot battles and the strategy we are focusing on. Here are the three main goals of the code that you will be writing:

  • The robot needs to stop when it sees white to keep it from driving out of the arena.
  • The robot needs to detect when another robot is close so that it can push them forward and drive them out of the arena.
  • The robot needs to be steady and consistent to avoid any unnecessary movements that may cause our robot fall out of the arena.

Let's double-check our ports and start writing the code to achieve these goals.

The ports

Before you write your code, it is good to make sure all the motors and sensors are plugged in properly. Using Port View, you can double-check the proper ports. The wheel motors will need be plugged into ports E and F. The distance sensor needs to be plugged into port A. The color sensor will need to be plugged into port C.
