We are pleased to bring out our first edition of “ Mechatronics” for engineering and technology students. This book is written to serve the needs of undergraduate students embarking on an introductory course in Mechatronics. This book is designed to meet the requirement of revised syllabus prescribed by the Anna University, Chennai, Tricky, Coimbatore & Tirunelveli for 7th semester Mechanical engineering students of its affiliated colleges.

This book consists of 5 units as follows.

Unit 1 Deals with the introduction to mechatronics systems such as concepts, need, emerging areas, and classification of mechatronics. It also deals with different types of sensors and  transducers such as potentiometers, LVDT, capacitance sensors, strain gauges, eddy current sensor, Hall effect sensor, Temperature sensors, light sensors with simple illustrations, examples, advantages, disadvantages and applications.

Unit 2 Is concerned with Microprocessor system, architecture, pin configuration, addressing modes. Instruction set helps to design a system and timing diagram shows how the operations are performed. Further it deals with basics of microcontroller.

Unit 3 Addresses the representation of various systems and their knowledge. Block diagrams representation, interfacing mechanism and their functions are covered with simple description. It also deals with the temperature control and stepper motor control, their operation and implementation with programs.

Unit 4 Provides introduction to programmable logic controller, basic structure of PLCs, input and output devices, ladder programming and practical examples.

Unit 5 Illustrates construction and working principle of different types of stepper and servomotors with its advantages and disadvantages. It also covers design concepts of mechatronic systems and case studies such as pick and place robot, engine management system, and automatic car park barrier.
