DESCRIPTION:Speaker: Katia Bertoldi\nhosted by Scott Waitukaitis\nAbstract:
  Multistable structures can reversibly change between multiple stable conf
 igurations when a sufficient energetic input is provided. While originally
  the field focused on understanding what governs the snapping\, more recen
 tly it has been shown that these systems also provide a powerful platform 
 to design a wide range of smart structures.In this talk\, I will first sho
 w that pressure-deployable origami structures characterized by two stable 
 configurations provide opportunities for a new generation of large-scale i
 nflatable structures that lock in place after deployment and provide a rob
 ust enclosure through their rigid faces. Then\, I will demonstrate that th
 e propagation of transition waves in a bistable one-dimensional linkage ca
 n be exploited as a robust mechanism to realize structures that can be qui
 ckly deployed. Finally\, while in the first two examples multistability is
  harnessed to realize deployable architectures\, I will demonstrate that b
 istable building blocks can also be exploited to design crawling and jumpi
 ng robots. Unlike   previously proposed robots that require complex inpu
 t control of multiple actuators\, a simple\, slow input signal suffices to
  make our system move\, as all features required for locomotion are embedd
 ed into the architecture of the building blocks.
