EV3P_cover_new-webProgramming can be some of the most difficult and most exciting parts of working with LEGO MINDSTORMS. Seeing a creation come to life can simply be magical (#mindstormsmagic), but is a daunting task for many. With a slew of books on the market for EV3, few focus almost completely on programming. The Art of LEGO MINDSTORMS EV3 Programming by Terry Griffin does a good job of making programming something anyone can do.

First the quality of the book is simply awesome! No Starch Press has an excellent pulse on the MINDSTORMS community and the durable book in full color goes a long way in helping you learn how to program a robot. Great content can often be impaired by back and white images or cutting corners in the publishing process. This book, like The LEGO MINDSTORMS EV3 Discovery Book and The LEGO MINDSTORMS EV3 Idea Book, is made well and will last a long time. (Comes in handy since I suspect you will referring to the book more than a few times.)

The author guides you though building a basic bot and programming it to complete various tasks. These range from things like line following and navigation. Griffin also goes over sensors in both the education and retail kits of EV3, making it a good resource for just about anyone.

Like any good MINDSTORMS reference, there is good discussion on each sensor and how that relates to programming. Griffin also discusses each programming block in good details. This helps create the logical links for any new programmer. One of the unique parts of the book is how practical it is. Most books present turnkey bots and programs. This does wonders for getting you started, but might not be as much help in the classroom or on your FIRST LEGO League team. The author walks the reader through the process of experimenting with some of the basic sensor views as you can see in the picture, left. These sorts of skills work well there is no one correct solution to the challenge.

Overall I was really impressed with the book. My only criticism is that it very much revolves around one robot. Sometimes how you use a sensor in software varies on physical construction of the bot. Take my latest bot Creep3r for example. While I use the IR and touch sensors in a straight forward way, the use of the color sensors detecting the doors and acting as part of the explosion is quite unique. It makes for a slightly more complex program, but makes the bot more exciting. That said, when you begin to use sensors in more unique ways such as sensing internal robot functions instead of the environment, that is a bit more complex. I would say this is a very minor drawback of the book, but would certainly be an exciting topic for a future book to explore.

Hands downs this is one of the best programming references on the market. I would say that The Art of LEGO MINDSTORMS EV3 Programming is a must have for anyone who is getting starting creating robots. Couple this book with The LEGO MINDSTORMS EV3 Discovery Book and you have an excellent set of references for any new EV3 owner!

This book review has taken me longer than usual. I have had a copy of this book for a while now, but I literally just finished it. The reason is not what you might expect. To put it simply, I got caught up in the book. I cant recommend this book enough. Laurens Valk did it again!

The LEGO MINDSTORMS EV3 Discovery Book is an essential book for both new and old MINDSTORMS builder alike! First off, the print quality off the book is excellent and this is key. As I spent hours building and referencing the diagrams in the book, it was helpful to have full color and high resolution images. As any LEGO builder knows, some parts are hard to see and the high quality images, coupled with Laurens’s excellent building instructions made constructing each bot a breeze.

If you have read any of Laurens’s other books, some of the bots might seem familiar. (SNATCH3R for example) EV3 is an awesome new platform and seeing the bots upgraded to take advantage of all the updates.  Laurens has bots for everyone, from cars to bugs. Each bot is an extreme joy to construct and program. The book provides excellent programming instructions to get you started, but like any LEGO set, the true excitement comes from building on that idea. For each bot, there were countless moments of “oh I bet I could made it do that!”. For example, I added a marker and had it drawing shapes on the floor (and then had SNATCH3R following the line!).

This would be super useful for teachers and FIRST LEGO League students.  One of the most innovative things Laurens presents is the use of graph paper with LEGO. As you can see in the image left, the grid really works well for figuring out angles and layout bot designs. This makes building complex mechanical designs or even super large robots significantly easier. Laurens uses this technique for more than just triangles, but you will need to get the book to see those!

In case it wasn’t clear by this point, I have really enjoyed this book. The book is a few hundred pages of LEGO MINDSTORMS awesome. I have been building robots with LEGO MINDSTORMS for well over a decade and a half and yet I still learned new techniques from The LEGO MINDSTORMS EV3 Discovery Book. I cannot recommend this book enough. Every LEGO MINDSTORMS builder will find something they enjoy in this book.  Don’t be surprised if you spend countless hours building, programming, and playing. It is an excellent reference that I am sure you will be visiting multiple times. In fact, this book hasn’t made it to my shelf yet. I think it might have a permanent home on my desk. Play well!
