Abstract:

Prof. Ravi Banavar

From the mobility of living creatures to the motion of mechanical systems like robots, automobiles and autonomous vehicles, locomotion is fundamental to many aspects of life. From a physics viewpoint, the mechanism of locomotion provides a rich area of study, intertwining many physical laws and phenomena; from a mathematical viewpoint, the area illustrates the application of many new theoretical paradigms to analyze the problem, and from an engineering viewpoint, understanding locomotion of organisms enables us to build gadgets that seek to emulate such organisms. In this talk I shall begin with an introduction to the macro view of this area, followed by the natural geometric framework to study these problems, then introduce the notion of locomotion in the micro (and nano) world. In particular, I shall introduce the area of locomotion in low Reynolds number (E-coli, sperm cells), the salient mechanics associated with such environments, followed by a topic of particular interest, controllability of these organisms.
