G. K. Ananthasuresh has taught this course once and has extensive presentation material based on numerous workshops he has conducted on the subject in the US and India. The instructor has been working in this field right from the inception of the field. He is associated with it for nearly 25 years and has contributed to its development and identifying applications. He has also played a major role in defining systematic design methods for compliant mechanisms.
