Acknowledgements

I would like to express my gratitude to the readers of my previous two books on ROS (ROS). Actually, they encouraged me to write one more book on ROS itself.

I would like to thank the Packt Publishing team for giving support for publishing my books. It may have been a distant dream without you all.

I would especially like to thank Amedh Pohad and Namrata Patil of Packt Publishing, who guided me during the writing process. Thanks for all your suggestions.

A special thanks to Ruixiang Du and all other technical reviewers for improving the content and giving good suggestions. Without your suggestions, this book may not have become a good product.

The most important thing in my life is my family. Without their support, this would not have been possible. I would like to dedicate this book to my parents, who gave me the inspiration to write this book. This is my third book about ROS. Thanks for the constant support.

I would also like to mention my previous company, ASIMOV Robotics, who provided components for a few projects in this book. Thank you very much.

I thank all the readers who made by previous books successful. I hope you guys also like this book and make it successful.
