Abstract

Origami, the ancient art of paper folding, has inspired the design of engineering devices and structures for decades. The underlying principles of origami are very general, which has led to applications ranging from cardboard containers to deployable space structures. More recently, researchers have become interested in the use of active materials (i.e., those that convert various forms of energy into mechanical work) to effect the desired folding behavior. When used in a suitable geometry, active materials allow engineers to create self-folding structures. Such structures are capable of performing folding and/or unfolding operations without being kinematically manipulated by external forces or moments. This is advantageous for many applications including space systems, underwater robotics, small scale devices, and self-assembling systems. This article is a survey and analysis of prior work on active self-folding structures as well as methods and tools available for the design of folding structures in general and self-folding structures in particular. The goal is to provide researchers and practitioners with a systematic view of the state-of-the-art in this important and evolving area. Unifying structural principles for active self-folding structures are identified and used as a basis for a quantitative and qualitative comparison of numerous classes of active materials. Design considerations specific to folded structures are examined, including the issues of crease pattern identification and fold kinematics. Although few tools have been created with active materials in mind, many of them are useful in the overall design process for active self-folding structures. Finally, the article concludes with a discussion of open questions for the field of origami-inspired engineering.

  • Understanding the full space of crease patterns as a function of folding energy is crucial for self-folding origami applications.

    “Understanding the full space of crease patterns as a function of folding energy is also crucial for self-folding origami applications13”

    From Self-folding origami at any energy scale (2017) · cites this paper as [13]

    Section 4, “Crease pattern/fold kinematics design” (page unavailable), says identifying a suitable crease pattern and folding sequence is important for active self-folding structures. It does not say that understanding the full space of crease patterns as a function of folding energy is crucial; searches for that relationship and for “folding energy” found no supporting passage. (LLM, conf=0.83)

  • The proposal is conservative-it does not require specific directional information at hinges, temporal staging, or using nonflat sheets.

    “Thus, our proposal is conservative—it does not require specific directional information at hinges6, temporal staging45, or using nonflat sheets37.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
