Arc-heating actuated active-morphing insect robots

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 27, 2025

In nature, insects can swiftly move and actively morph to adapt complex varied conditions. However, replicating this capability in insect-scale robots requires sophisticated structural designs, which are difficult achieve at such a small scale without fundamental hardware innovations. This work proposes coupling mechanism between actuation morphing by combining an arc-heating actuator shape memory alloy wires, presenting fast robot (83.4 body lengths per second) capable of active self-recovery. The is designed provide the kinetic energy thermal essential for deforming wires. compress its thickness traverse through gap 70% height smoothly within 2.2 seconds amphibious. Furthermore, after enduring pressure 5 million times weight, flattened, but fully recovers original size performance just few seconds. Replicating swift movement small-scale challenging. authors developed using achieving rapid movement, morphing,

One-degree-of-freedom flat-foldable thick-panel origami-kirigami structures: modular arrays and closed polyhedra

Communications Engineering, Год журнала: 2025, Номер 4(1)

Опубликована: Апрель 1, 2025

Origami structures hold promising potential in space applications, such as ultra-large-area solar arrays, deployable stations, and extra-terrestrial modular foldable buildings. However, the development of thick-panel origami has been limited, relying on a few typical patterns without comprehensive design theory for multi-crease, multi-vertex configurations. Additionally, realizing closed Polyhedra presents substantial challenges. Here, we introduce methodology inspired by kirigami principles one-degree-of-freedom (one-DOF) flat-foldable origami-kirigami structures, including scalable arrays polyhedral structures. The incorporate mixed four-crease vertices (2n + 4)-crease vertices, enabling one-DOF flat-foldability expansion units. tetrahedrons, square pyramids triangular prisms, possess inward-flat-foldability structural closure after unfolding. This novel framework is capable from centimeter to meter scale, validated kinematic analysis prototype experiments.
