Thanks to movies and TV, the notion of the robot as a mechanical companion and servant has become a common concept. As interest in robots grew, a number of books showing how to build robots at home began to appear. These books, however, were very technical, showing how to build computer-controlled mobile platforms that are considered by most to be true robots. My interest in robots leaned more toward the popular concept of robots as humanlike friends and servants. I did not have the technical skill or funds to build a computer-controlled robot, so I decided to develop a robot that would fit the popular image of robots and not be too difficult to complete or expensive to build. The result was Questor. While working on Questor, I tried to develop a project that I, as a beginner, could complete with little technical skill, using tools I had in my workshop. Also, I wanted Questor to look and function like a robot butler, a form I felt best fit the friend/servant theme. For this reason I needed a people-sized robot that would have great presence. I concentrated more on form than sophistication to develop an impressive looking, but relatively simple-to-build, project—a beginner’s project. Later, when I decided to write a book about the project, I wanted to avoid weaknesses I found in other how-to robot books. This book is heavily illustrated, helping to take the guesswork out of Questor’s construction. Next, the book deals only with the construction of the robot, and not the theories on which it is based. This type of information is best derived from specialty electronics and robotics books. I have included I ix Copyright 2002 The McGraw-Hill Companies, Inc. Click Here for Terms of Use.
