DESCRIPTION:My group is developing a roadmap for elastic morphic materials
  to replace bulky electric motors in miniature robots requiring large mech
 anical work output.\n\nFirst\, I will describe the mechanics of coiled mus
 cles made by twisting nylon fishing lines\, and how these actuators use in
 ternal strain energy to achieve a “record breaking” performance. Then 
 I will describe intriguing hierarchical super-\, and hyper-coiled artifici
 al muscles which exploit the interplay between nonlinear mechanics and mat
 erial microstructure. Next\, I will describe their use to actuate the dyna
 mic snapping of insect-scale jumping robots. The combination of strong but
  slow muscles with a fast-snapping beam gives rise to dynamic buckling cas
 cade phenomena leading to effective robotic jumping mechanisms.\n\nThese e
 xamples shed light on the future of automation propelled by new bioinspire
 d materials\, nonlinear mechanics\, and unusual manufacturing processes.
