1. An actuatable structure, comprising a set of discrete units, wherein the set of discrete units is assembled into the structure according to a lattice geometry that allows for reversible deformation without compromise of the strength of the structure, wherein a majority of the discrete units are each connected, or are connectible, to at least two other units in the set according to the lattice geometry, and wherein a coordinated reversible spatially-distributed deformation of at least part of the structure occurs in response to changes in load or actuation.
