DESCRIPTION:Abstract:\n\nMy group is developing a roadmap to replace bulky
  electric motors in miniature robotic functions requiring large mechanical
  work output.\n\nFirst\, I will describe the mechanics of hierarchical sup
 er-\, and hyper-coiled artificial muscles which generate contractile motio
 n during actuation. I will explain our current understanding of the interp
 lay between their nonlinear mechanics and material microstructure. Next\, 
 I will describe their use to actuate the dynamic snapping of insect-scale 
 jumping robots. The combination of strong but slow muscles with a fast-sna
 pping beam gives rise to dynamic buckling cascade phenomena leading to eff
 ective robotic jumping mechanisms.\n\nThese examples shed light on the fut
 ure of automation propelled by new bioinspired materials\, nonlinear mecha
 nics\, and unusual manufacturing processes.\n\n\nBio:\n\nSameh Tawfick is 
 a Visiting Professor in the University of Cambridge and a Beaufort Visitin
 g Fellow in St John’s College. Prof. Tawfick's home institution is the U
 niversity of Illinois Urbana-Champaign where he is currently an Associate 
 Professor of Mechanical Science and Engineering\, having received the Dean
 ’s Award for Excellence in Research. Sam obtained his PhD from the Unive
 rsity of Michigan and was a Postdoctoral Associate at the Massachusetts In
 stitute of Technology. He studies advanced materials\, nonlinear mechanics
 \, and manufacturing processes. He is the recipient of young investigator 
 awards from the US Air Force\, ASME\, and SME.  His teaching awards at the
  University of Illinois include The Everitt Award for Teaching Excellence\
 , The Two-year Alumni Teaching Award\, and The Engineering Council Stanley
  H. Pierce Award for Empathetic Student-faculty Cooperation.\n\n\nJoin Zoo
