Gordon McComb is helping us out on the site this month in support of the release of MAKE Volume 27, our latest robotics issue, and for our monthly Robotics theme here online. Gordon has also just release the fourth edition of his groundbreaking book, Robot Builder’s Bonanza. The first edition of this book was released in 1987 and pretty much launched the hobby robotics field. This was the book that got me into robotics, which lead me into electronics (and Forrest Mims’ book), hardware hacking, and most of my high-tech making interests.
