Absolute beginner's guide to building robots / Gareth Branwyn.

Enhanced descriptions from Syndetics:

Finally, a robots book for people who don't know the first thing about robotics! Absolute Beginner's Guide to Robots is well-written, inviting, and action-packed, with engaging ideas and fascinating factoids about robots and robot-related arts and sciences. You are led gently into the intimidating world of robotics, but nearly 400 pages later, you emerge with a respectable knowledge of robot history, the major fields and "schools" of robotics today, and the basic skills and resources needed to create hobby robots. By the end of the book, you will be the proud owner of three bots, the first two of which demonstrate key robotic principles. The third is a programmable/expandable robot, which serves as a platform for future experimentation. And best of all, these robots are built with simple to get and inexpensive parts - many of which you already have around the house!
