Query: Missing Parts

Cute book. If you want learn about the history of robots and to learn how to make only 3 of them then this is the book for you.The part list should be revised to include all parts used and recommended. You should read the projects carefully unless you want to spend time travelling back and forth to your local electronics store. Although the projects start with a parts list, the author tends to add parts to a project in the middle of the text.
