“…Origami inspired structures can be used as flat sandwich panels, and as cores in cylindrical structures [51]. One of the most commonly studied origami patterns for structural applications is the Miura structure [52][53][54][55]. Liu et al used the Miura pattern to create carbon-fibre-reinforced cylindrical foldcore sandwich structures [56].…”

Origami patterns can be used to inspire the designs of structural materials with beneficial properties, such as low strength-to-weight ratios. This study explores the design, manufacturing, and mechanical properties of three different origami-inspired shapes, as well as three different material combinations for each shape, through dynamic impact testing and quasi-static compression testing. The commonly studied Miura origami pattern will be compared to two uncommon patterns: a square-based pattern and a triangular-based pattern. The samples are 3D printed and the material combinations include one rigid and one flexible polylactic acid (PLA) sample, and one multi-material configuration with flexible PLA crease areas and rigid PLA origami faces. The rigid square sample was the most effective at absorbing a single drop-weight impact load and the flexible Miura pattern was most effective at absorbing impact loads when multiple drops were performed on the same sample. The rigid triangular structure withstood the highest loads during the quasi-static compression testing. A finite element model of the quasi-static compression test was built to enhance the analysis of the various tested configurations.

“…Research work in these areas can be accomplished through hierarchical programming, from modelling and fabrication to the operation of the finished device [21,22]. The dynamic displacement of the material structure can be controlled (and to a much greater extent than before) by changing the geometric and material parameters through a combination of techniques for selecting the shapes of individual elements, the way they are connected, and the properties of composite structures [23]. This makes it possible to create stretchable electronics, deformable devices, self-assembled fabrication, etc.…”

The problem of computerising the design and development of 3D-printed chainmail with programmed directional functions provides a basis for further research, including the automation of medical devices. The scope of the present research was focused on computational optimisation of the selection of materials and shapes for 3D printing, including the design of medical devices, which constitutes a significant scientific, technical, and clinical problem. The aim of this article was to solve the scientific problem of automated or semi-automated efficient and practical design of 3D-printed chainmail with programmed directional functions (variable stiffness/elasticity depending on the direction). We demonstrate for the first time that 3D-printed particles can be arranged into single-layer chainmail with a tunable one- or two-directional bending modulus for use in a medical hand exoskeleton. In the present work, we accomplished this in two ways: based on traditional programming and based on machine learning. This paper presents the novel results of our research, including 3D printouts, providing routes toward the wider implementation of adaptive chainmails. Our research resulted in an automated or semi-automated efficient and practical 3D printed chainmail design with programmed directional functions for a wrist exoskeleton with variable stiffness/flexibility, depending on the direction. We also compared two methodologies of planning and construction: the use of traditional software and machine-learning-based software, with the latter being more efficient for more complex chainmail designs.

Compared to many rigid robots, emerging soft robots possess higher adaptability and safety owing to their compliance, [1,2] making them a promising solution for human-robot interaction, [3,4] manipulation, [5,6] and search and rescue. [7] Instead of only having one state (soft or rigid) in a robot, many scenarios necessitate both soft and rigid properties. For example, when picking an item of varying softness, shape, and weight using various motions, such as grasping and fiddling, a packaging robot should be rigid enough to grasp heavy items but soft enough to grasp fragile or irregular items while also being capable of quickly switching between these two states. [2,8,9] While exploring dangerous and confined environments (e.g., post-earthquake rescue and industrial pipeline inspection), the robot should be sufficiently compliant to adapt to the cluttered environment and rigid to transport a large gap. [10,11] Moreover, if a robot approaches a rugged surface with a heavy payload, it should be sufficiently compliant to move on the surface and rigid to support the payload. [12,13] To circumvent this problem, researchers attempted to integrate rigid and soft robots. One approach is to convert a robot from a rigid to a soft state and vice versa, which requires a variable-stiffness mechanism. This mechanism has been widely used in wearable robots, [14] manipulators, [7,15] and continuum
