There are a few popular textbooks out there for mechatronics. Given the diversity of opinion in the field as to what mechatronics is, let alone how it should be taught, the approaches that are taken can be quite varied.
What is your favorite mechatronics textbook, and why?
Personally, I've always been partial to Bolton, perhaps since it was the first book I used. Nostalgia aside, I really like the depth of complexity and slant towards a more practical and hands-on approach. That being said, I also have The Mechatronics Handbook by Bishop, and Introduction to Mechatronics and Measurement Systems by David Alciatore and Michael Histand in my collection.
