I'm an author of 8 books in Robotics. Here are some of the lessons I have learned from this.
Pros
1) Great visibility in the robotics community
2) Started getting good consulting projects
3) Started getting Royalties(Passive income)
4) People start identifying me in conferences
5) Got the invitation to do research in good universities
6) Got good patience which is very useful while working with the robots
7) Knowledge also doubled (I have to do a lot of homework in order to write things in the book).
8) Self-satisfaction to became an author
Cons
1) Time consuming
2) Need full-time dedication
3) Royalties are very low (only 17% of the book price)
4) Books will easily come online for free download. This will definitely demotivate us to write another book.
5) Books will outdate very easily (Technical books), so you may have to update it by writing a new edition.
6) Getting good income from books is like getting a lottery. It will only happen to a few people.
