This work analyzes the global stable states of our metasheet by investigating the interrelations between units and their spatial arrangement. We utilized a reduced-order model base on spring lattices to determine the final shape of our metastructure in terms of the number of units, distribution, and unit cell geometric parameters. We further examine the interaction between units and its effect on the final shape and its role in the generation of geometrically frustrated stable states. Furthermore, we examine the effect of inversion path and unit interactions in different applications, such as soft multistable actuators and reconfigurable structures. This opens a route for the fast design of multistable soft robots and shape targeting in soft metamaterials.
