Page 1: The LEGO MINDSTORMS EV3 Idea Book: 181 Simple Machines and Clever Contraptions

The LEGO ® MINDSTORMS ® EV3 Idea Book explores dozens of creative ways to build amazing mecha-nisms with the LEGO MINDSTORMS EV3 set. Each model includes a list of the required parts, minimal text, and color-ful photographs from multiple angles so you can re- create it without the need for step-by-step instructions.

You’ll learn to build cars with real suspension, steerable crawlers, ball-shooters, grasping robotic arms, and other creative marvels. Each model demonstrates simple mechanical principles that you can use as building blocks for your own creations.

Best of all, every part you need to build these machines comes in one LEGO set (#31313)!

IntroductionThe LEGO MINDSTORMS EV3 set is designed to allow builders of any age to create robots, vehicles, and other contraptions with moving parts.

Each model in this book is only a small mech-anism, but you can make an infinite variety of larger models by combining these ideas. LEGO bricks aren’t designed to fit in just one specific place or in one particular way. Your imagination is your guide when building with LEGO, and I hope that you will create your own wonderful masterpieces using this book as inspiration.

To build the models in this book, all you need is the LEGO MINDSTORMS EV3 set (home edition #31313).

Where Are the Words?Other than this brief introduction and the table of contents, this book has almost no words. Instead, you’ll find a series of photographs of increasingly complex models, each designed to demonstrate a mechanical principle or building technique.

While the book lists the pieces needed for each model, it does not include step-by-step building instructions. Look at the photographs taken from various angles and try to reproduce the model. Building in this way is something like putting together a puzzle. You’ll get the hang of it after a little practice.

This is an idea book; it’s about imagination. Rather than tell you what to see or think when you study the models, I encourage you to interpret them in your own way. Your interpre-tations will lead you to invent your very own models or use my mechanisms in entirely new ways!

What About Programs?This book is about exploring the mechanical side of EV3 and robotics, rather than program-ming. You’ll need only a few simple programs to test out your mechanical creations. Prepare these three simple programs in advance.

A few of the models in this book require spe-cial programs. Take note of these programs, as they are written to avoid damaging parts by overextending a mechanism’s range of motion.

This program will rotate the Large EV3 motor, then rest for a period.

This program will rotate the Medium EV3 motor, then rest for a period.

This program will rotate two motors, then rest for a period.
