DESCRIPTION:Kinematical reconfigurable structures can be used as morphing 
 platforms. They can be integrated with multi-physics functional elements t
 o achieve reconfigurable properties associated with electromagnetic\, opti
 cal\, acoustic\, thermal\, and mechanical performances. However\, one fund
 amental problem for such platforms is the lack of a systematic design appr
 oach to practically achieve arbitrarily prescribed geometric reconfigurati
 on. Designs based on high degree-of- freedom (DOF) mechanisms can achieve 
 almost arbitrary reconfiguration but struggle with actuation and control. 
 Pneumatic control\, smart materials with shape memory or magnetic properti
 es\, and structural multi-stability have been applied to alleviate the pro
 blem\, but the resultant accuracy and achievable configurations are limite
 d. Designs based on low DOF mechanisms can be actuated easily but can only
  deform in a simple way. A robust design framework that can achieve invers
 e designability\, easy actuation\, and high accuracy/stability is yet to b
 e established. This talk proposes a design method for arbitrarily prescrib
 ed geometric reconfiguration considering actuation and manufacturing feasi
 bility. It employs a new multistability design method and a novel path- fi
 nding algorithm. 2D and 3D examples are demonstrated\, which can be design
 ed for 2-3 prescribed configurations with high stability and easy actuatio
