Robot Building for Beginners

Craig Maloney writes "Growing up, I was immersed in the science fiction tales of my time. Space travel and laser guns were fascinating, but even more fascinating to me were the science fiction movies that involved robots; the complicated machines that performed great feats of impossible skill, dexterity, and amazing computation. When Tomy and Heathkit released their personal robots, I tried in vain to con my parents into believing that a personal robot might improve our quality of life in some way (mine more than theirs because I would obviously have been the skillful programmer of these robotic devices). While Robot Building for Beginners won't have you creating anything as complicated as C3PO or even a HERO Jr., it will show you how to build a simple robot from the ground up, and will help those who don't have the rudimentary electronics experience required to master these skills." Read on for the rest of Maloney's review. Robot Building for Beginners author David Cook pages 568 publisher Apress rating 10 reviewer Craig Maloney ISBN 1893115445 summary A complete "back-to-basics" guide to designing and building a simple robot

Beginner means beginner I didn't actually build the robot presented in the book, but after reading it, I feel confident that I wouldn't have any problems building it.

Robot Building for Beginners is not a misnomer. If you have an area set aside in your home that you call your electronics lab, and know how to use breadboards, multimeters, and soldering irons, you may not get as much out of this book. If, however, you have to clear off your project area in order to eat and don't know the first thing about where to begin to build a robot, then this book will be a roadmap on your journey to proficiency. Loads of pictures and very frank discussion make this book a pleasure to read, and a real learning tool.

The book begins with a brief introduction to the robot hobby and some interesting robot pieces and projects. Next is an informative chapter on where to purchase the parts for the robot, with an emphasis on getting parts cheaply. The author also gives some hints on how to order parts cheaply through quantity discounts as well as part substitution. The book then takes a brief detour onto the subject of safety, with such sage advice as using items safe for the reader (lead-free solder, safety goggles, and dust masks) and items safe for the electronics (circuit breakers, grounded plugs, and following instructions). The author also briefly cautions against making dangerous robots (like the ones on BattleBots) because they can not only be very dangerous, but can also be hazardous to test (sorry, guys. :) ).

From there the author dedicates two chapters to selecting and using one of the more important pieces of equipment for electronics projects: the multimeter. The author presents some sage advice for selecting an appropriate, accurate mutimeter within your budget. I used this knowledge to pick out a very nice, affordable multimeter of my own (a Triplett 9025, for anyone who is interested).

Next, a brief discussion on numbers and units, followed by a chapter on robot line-following rounds out the basics section of the book. The sandwich robot (so named because the author uses a sandwich container for the body) is introduced in the chapter on line-following, and forms the basis for the project that is built through the rest of the book.

Parts is parts

The next few chapters form an excellent introduction to the electronic components that make up the sandwich robot. From an informative discussion on batteries (the results may surprise you. It certainly changed how I look at batteries) to components like breadboard, transistors, variable resistors, and IC chips. Each chapter introduces a particular component, describes what it does, and give some very useful tips for using the component effectively. The components are introduced by demonstrating how they fit together in simple circuits. I found myself learning a great deal about each of the components and how they fit together. Next the book tackles the more mechanical aspects of the robot (motors, tires and couplers) and how to select, work, and assemble them into the final project. Two chapters follow, dealing with everyone's favorite topic: soldering. The first chapter handles the equipment needed for soldering, while the next chapter handles how to solder properly. Even the most nervous soldering neophyte will feel right at home with a soldering iron after these chapters.

Putting it all together Time to put the knowledge together! The next chapter tackles the motherboard of the robot. A schematic and lots of pictures with layouts and hints help make what could be a difficult process into something less frightening. Cleaning and testing the motherboard rounds out the last part of the chapter. Then it's on to the body construction and the launching of the robot! The last chapter talks about other goodies such as LCD screens, real microprocessors, and other components worth checking out. There's also a quick mention of robotics clubs and projects the author would like to take on. The author is a robotics enthusiast, and it shows with his candid writing. What's in it for me?

Robot Building for Beginners is a great resource for those who may not have a background with electronics. I found myself learning all sorts of useful information from this book. Those who may not be interested in building a robot will still find this book useful for a good primer in electronics and electronic circuits. They may also be convinced by the author's sheer love for robot tinkering to explore the world of robotics. People with an electronics background may not be interested in this book as much as a rank beginner, but don't let that dissuade you from checking out this excellent book. I can easily recommend this book to anyone with a passing interest in electronic circuits and robotics. The robots you build from this book may not be able to serve drinks, or repair a damaged X-Wing fighter, but you'll definitely have fun building them.

Robots is dying

[Anonymous Coward]

It is official -- Netcraft confirms: robots is dying One more crippling bombshell hit the already beleaguered robots community when IDC confirmed that robots market share has dropped yet again, now down to less than a fraction of 1 percent of all servers. Coming on the heels of a recent Netcraft survey which plainly states that robots has lost more market share, this news serves to reinforce what we've known all along. robots is collapsing in complete disarray, as fittingly exemplified by failing dead last [samag.com] in the recent Sys Admin comprehensive networking test. You don't need to be a Kreskin [amazingkreskin.com] to predict robots's future. The hand writing is on the wall: robots faces a bleak future. In fact there won't be any future at all for robots because robots is dying. Things are looking very bad for robots. As many of us are already aware, robots continues to lose market share. Red ink flows like a river of blood. free robots is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time free robots developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: free robots is dying. Let's keep to the facts and look at the numbers. OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. Robots/Droids posts on Usenet are about half of the volume of NetRobots posts. Therefore there are about 700 users of robots and droids. A recent article put free robots at about 80 percent of the robots market. Therefore there are (7000+1400+700)*4 = 36400 free robots users. This is consistent with the number of free robots Usenet posts. Due to the troubles of Walnut Creek, abysmal sales and so on, free robots went out of business and was taken over by USRobotics who sell another troubled droid. Now BSDUSRobotics is also dead, its corpse turned over to yet another charnel house. All major surveys show that robots has steadily declined in market share. robots is very sick and its long term survival prospects are very dim. If robots is to survive at all it will be among OS dilettante dabblers. robots continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, robots is dead. Fact: robots is dying
