DESCRIPTION:Current infrastructure is designed and built such that it must
  simultaneously comply with all possible loads. This leads to overdesigned
  structures that are inefficient in terms energy and cost. A structure tha
 t can self-identify damage\, adapt\, and learn for future events addresses
  the emerging field of intelligent infrastructure and structural health mo
 nitoring through inspiration from biology. To achieve this type of structu
 re requires balance of structural engineering\, architecture\, mechanical 
 engineering\, computer science\, and robotics. Although deployable structu
 res are already fairly common\, deployable active structures that change s
 hape either autonomously or remotely to accommodate challenging environmen
 ts are rare. Tensegrity structures are geometrically non-linear\, they are
  ideal candidates for studying deployable structures (http://youtu.be/FeXx
 jerleZE). Through actuation\, origami-inspired structures can also be repe
 atedly deployed for ease of transportation and installation. The grand cha
 llenge of this work is addressing uncertainties between modeling and exper
 imental testing for large-scale shape changing structures. To address this
  challenge\, SMARTI lab employs optical tracking and computer vision for h
 igh-definition measurement and additive manufacturing for optimized connec
 tions. This seminar will present work on adaptive and deployable structure
 s using sustainable materials and control algorithms for resilient infrast
 ructure.
