Mechatronics is a rapidly developing interdisciplinary field of engineering, which comprises the development of various computers integrated electro mechanical systems.

It is an integration of mechanical engineering, electronic engineering, computer engineering and control and instrumentation engineering.

This integration facilitates the production of complex engineering systems with a high level of performance, reliability and value at a low price.

Due to these aspects, industrial sector is rapidly adopting such integrated systems in manufacturing processes.

Hence it is essential for the students to have knowledge of this multidisciplinary field. This course covers sensors and actuators, develop simple control algorithms and use or develop advanced functional materials for the design of mechanical systems such as anti-lock brakes, engine control units, disk drives, cameras, service and surgical robots and artificial hearts.
