Hello Lentin,
I have your 1st edition book for 2 years now and like to know “what has changed”.
I like your 1st edition very much, but I did not agree 100% with the extension “using python” .
Do you have added more python samples ?
Last but not least, this book is a MUST HAVE for all ros users.
Cheers
Christian
