Abstract

The bending stiffness of a structure is highly dependent on its shape, and this relation can be utilized to allow for a structure to morph into different shapes during deformation. This paper focuses on shape-morphing into multiple shapes (Multi Shape-Morphing), and presents a design method for a parametric
structure consisting of beams, that is able to approximate a set of objective shapes during deformation by exploiting its geometry. Several designs are generated with this design method and experimental validation has been performed on several physical models verify the multi shape-morphing performance. A sensitivity analysis has been conducted on relevant design vari-
ables of generated designs to identify their relative importance concerning the structure’s multi shape-morphing performance. To demonstrate the feasibility of the proposed design method for use with exoskeletons, a human-scaled prototype has been designed, and validated.
