I’d like to thank my family for all their patience while I wrote this book. Special thanks to my wife, Liz, who spent countless hours reviewing the text and tolerated the robots inhabiting the dining room table.

This work would not have been possible without the help and support of Bill Pollock and the staff at No Starch Press. It was a pleasure to work with Seph Kramer, Laurel Chun, and Jennifer Griffith-Delgado. Their knowledge and expertise were instrumental in the completion of this project.

I’d also like to thank my tech reviewers, Daniele Benedettelli and Rob Torok. Their knowledge of the EV3, and robotics in general, was a big help in keeping the material relevant and technically correct.
