The process is painless with a solderless breadboard. Also covered in this chapter are: wire strippers, solid wire, jumpers, and pliers. A good setup for your breadboard is to connect a rechargeable 9 V battery and a switch, extend the buses, and add a power indicator.
This chapter shows you how to do it, along with methods of testing voltages throughout the board with a multimeter.
This chapter details variable resistors, such as fine-tuning potentiometers and photoresistor sensors. Just like the Robot Room web site, each circuit described in this book is first shown in schematic or wire diagram form and then illustrated on an actual breadboard. A comparator is a really useful chip. Often it is a supplemental component used to preprocess sensor data for a microcontroller on a robot.
In this case, the comparator is the brain of the line-following robot. A working knowledge of transistors is necessary to drive robot motors. What robot book would be complete without a close look at DC motors? This gave me an excuse to obtain and dissect a number of different motors and gearheads. I was even able to put most of them back together again. Possibly the longest chapter in the book, it lists the many characteristics of motors and how you might go about selecting the proper motors for your robot.
A table provides formulas for converting between different units of rotational force torque. Learn about the significance and phases of motor current usage. In this chapter, a particular gearhead motor is selected for the line-following robot. Additionally, flyback diodes are added for the protection of the transistors. From motors, we move on to wheels.
The type of wheel makes a bigger difference to a robot than most people think. This chapter describes some of the factors to consider, along with my favorite wheel manufacturer. I use this kind of coupler on nearly all of my robots. In fact, many people joke that they first look for the coupler whenever I present one of my robots.
After you read this chapter, you'll learn the simple secrets to making a coupler yourself without fancy machinery. And, as always, step-by-step instructions are provided. You can only proceed so far in robot building without soldering. This chapter describes some popular soldering tools and supplies, such as a soldering iron, stand, sponge, desoldering bulb, flux, and of course solder.
In fact, some parts are best left to removable connectors. This chapter describes my personal favorite, the Molex KK-series connector, along with the pieces and tool you need to attach connectors to your robot. This chapter also begins the soldering process for the line-following robot. Heat-shrink tubing, the hallmark of a professional, is also discussed.
The soldering section finishes with the complete schematic of the line-following robot. The choice of point-to-point wiring versus printed-circuit boards is covered, as well as expert tips for successful soldering. This chapter discloses a timesaving, yet uncompromising, body material. An easy technique for cutting holes in plastic is explained.
Also discussed: standoffs, screws, nuts, washers, nutdrivers, switch hardware, and acetone. Tweaking and adjusting often make the biggest difference between an ordinary robot and a great robot. Frame by frame analysis shows how the line-following robot is able to follow both light and dark lines. The limiting factors are revealed, as well as interesting ideas for enhancements.
This is one of my favorite chapters. In Robot Building for Beginners, Third Edition, any motivated person can be taught the basics so that they will learn to build a robot the size of a lunch box to autonomously walk.
Along the way you will learn the basics of wiring, electronics, mechanics and tooling so that you have the necessary skills to create more and more advanced robots. Finally you will learn an optional bit about 3D printing, as some of the parts can be 3D printed. Robot Building for Beginners, Third Edition provides basic, practical knowledge on getting started in amateur robotics.
There is a mix of content: from serious reference tables and descriptions to personal stories and humorous bits. The robot described and built in this book is battery powered and about the size of a lunch box. It is autonomous; that is, it isn't remote controlled. The characteristics and purposes of each major component resistor, transistor, wire, and motor are described, followed by a hands-on experiment to demonstrate.
Not only does this help the reader to understand a particular piece, but it also prepares them with processes to learn new parts on their own. An appendix offers an introduction to 3D printing and parts of the robot can, as an alternative, be "printed" using a 3D printer. Skip to main content Skip to table of contents. Advertisement Hide.
