“…Such phenomena are illustrated on intrinsically 2D structures like a classic kirigami pattern, where the bi-stable spherical kirigami [31] and multi-stable flat kirigami [32] are demonstrated respectively, and a similar type of multi-loop truss structures [33]. In terms of multi-stable origami, there are three common types, the first one is Kresling-tube-like structures [20,34], the second type is by stacking Miura patterns with symmetrically invertible layers [35,36], and the third one is by inverting a vertex and causing self-lock [37,38] which requires an additional pressing actuation. The comparison in terms of the generality of these three types is provided in Fig.…”

Multi-stable morphing structures can be self-locked, easily actuated, and generate impulsive motion, and origami mechanisms with thick panels have the practical combination of morphing ability and load-bearing capacity. In this paper, we combine the two and propose a method to design multi-stable thick-origami (MSTO) structures, where the stable configurations can be arbitrarily prescribed. Bi-stable degree-4 and tri-stable degree-6 vertices with the corresponding tessellations are designed, analyzed, manufactured, and experimentally tested. Compared to the original one-degree-of-freedom thick-origami mechanisms, the multi-stable/multi-compatible version in this paper has a larger design space with more achievable configurations due to the relaxation of compatibility constraints. In addition to the existent multi-stable origami designs, such as Kresling-ori tubes and vertex-inverting locking designs, this work provides a new form of multi-stable origami with 2 to 3 arbitrarily prescribable stable configurations. Preliminary applications like self-locking deployable furniture and an impulsive gripper are demonstrated, which suggest a promising and potential prospect in many engineering fields such as deployable architectures and robotic devices.
