1) This book explains the complete design methodology of autonomous systems in three simple rules, so designing a autonomous systems are on your finger tips just 1-2-3 and it's complete. 2) Very little knowledge of programming languages, assembly, microcontrollers etc are required, so pre-requisites of this book are very less, so anyone can just start and learn it from the beginning. 3) Two case studies are presented along with the source codes, circuit diagrams, datasheets etc that add the understandability of the user of the book. 4) It is tried to focus more on the concepts rather than merely making the reader to know how to design the autonomous systems. 5) Several examples,tutorials are presented at to increase the creativity and familiarity of the user. 6) Hardware and software modules are separately explained, that makes the clear picture in reader's mind,about the usage of different technology.
