3.0 out of 5 stars
doesn't actually show you how to build a robot, September 5, 2005
This review is from: Robotics Demystified (Paperback)
The folks at McGraw Hill graciously sent me a copy of Edwin Wise's new book, Robotics Demystified, for me to review. Unfortunately, I got it right around the time that I left for Hong Kong (study abroad) and I'm just now getting around to actually reviewing it.
The title calls it a "self-teaching guide" and the back cover reads; "Now anyone with an interest in robotics can gain a deeper understanding - without formal training, unlimited time, or genius IQ." So, I cracked open the book to find out if this is true or not.
Demystified is a relatively short 295 pages and contains 18 chapters. Example chapter names include, "Simple Machines", "Starting with Electronics", and "Intelligent Behavior." It is clear from the beginning that Wise is targeting this book to the complete novice. He says in the Preface, "There is no one 'robot technology,' so this book breaks the study of robots down into technology categories: the mechanics and framework of the robot, the electronics that make up its brain and nerves, and the control systems and programming that gives the robot life." Each chapter concludes with quiz questions to test your knowledge of each chapter.
The book starts off at a pretty low level (mechanical forces) and slowly (very slowly) builds on the knowledge. The forces chapter, and the following, "Simple Machines" discuss basic mechanical systems. All the mechanical systems described in the book deal only with LEGO pieces, so the reader never actually sees any other type of building materials. The mechanical systems are also presented as individual units and aren't ever assembled into a comprehensive "overall" system (aka, an actual robot).
After an introduction to mechanical systems (which is where Wise really shines) the book turns towards electronics and spends an entire chapter discussing the building blocks of electronics (electrons, electric fields, magnetic fields, etc.) in what seems a bit too low level for most robot hobbyist's needs. Another disappointment was the chapter on circuits, which was sadly lacking in basic tools for analyzing circuits and their behavior (it only contained a brief description of Ohm's law).
Another chapter dealt entirely with sequencing and programming, including Cam Control and Card Control - who seriously uses this anymore? The discussion on binary systems was also brief. The chapter on control systems didn't even mention block diagrams and discussed closed-loop feedback systems without any good examples in robotics (a good one would be a motor driver).
Another chapter was devoted to semiconductors, with discussion of BJT's and FET's, but this was sadly disconnected from real-world applications and circuits. Which, is the biggest problem I have with this book - there isn't any real world applications in robotics. The book lacked any discussion of sensors or microcontrollers, and only mentioned programming in a high-level way. There were no pictures of actual robots anywhere in the book.
I would say this book is definitely not for true beginners. It will only leave them more frustrated and confused. It builds a very nice foundation, but stops there, leaving the beginner to find yet another resource to link all the pieces together. Robotics Demystified only succeeds in clouding the really difficult part - putting everything together into a working robot.
If you're an "advanced beginner" this book might be for you, to enhance your knowledge, but if you're completely clueless, stay away.

4.0 out of 5 stars
an introductory text, January 29, 2005
This review is from: Robotics Demystified (Paperback)
A breezy little book that gives a general explanation of how to make your own robots. Very much a hobbyist's flavour, with a hands on approach emphasised. Wise tries to take a lot of the mystique out of the subject. He downplays any complexity in the design. This may ultimately limit what you can get out of the book. But if you have never had any prior exposure to robotics, it is still not a bad choice for a first text.

What was the Author Thinking?, April 28, 2008
This review is from: Robotics Demystified (Paperback)
Mr. Cox writes a very good review and, while I of course enjoy the warm glow of 5-star reviews, his 3-stars make sense in his context. You might even say three stars are generous, if you wanted this book as a hands-on guide to making a full robot right now.
In his review he asks the rhetorical question "...including Cam Control and Card Control - who seriously uses this anymore?", and I have a practical answer.
Everybody! Cams can be found everywhere!
Okay, now a serious answer. I took the title seriously; I wanted to demystify robotics -- so I tried to find basic, fundamental illustrations to show the concepts involved in robotics. Cam control? To illustrate sequential control, a form of programming. Punch cards? As the camel's nose into the tent of information representation, or some such thing.
Was this the right approach or not? Only the individual reader can decide; as an author, I take a chance, I shoot my ideas out into the air, and sometimes I hit the target and sometimes I miss.
The main problem Mr. Cox seems to have with the text is the lack of complex circuits, examples, robot programming, or any actual complete robots! For these needs there are lots of excellent existing books on the shelves... in fact, any one robotic technology requires a full book to do it justice.
I didn't want to write yet another robot or electronics cookbook. Instead, I wrote this -- a book with a different goal and perspective than what I already saw on the market. A book that tries to demystify what it means to be a robot, and to provide a look at the technologies and ideas that go into the making of a robot, with a number of simple examples to illustrate them. A book not targeted so much at the experimenter or builder, but to the curious and to the person who may be getting their very first look at the topic.
As for the cover descriptions and marketing blurbs -- alas, an author doesn't have much to say about those, and they often miss the intent of the book.
Edwin!
