Soft tubular actuators can be widely found both in nature and engineering applications. The benefits of include (i) multiple actuation modes such as contraction, bending, expansion; (ii) facile fabrication from a planar sheet; (iii) large interior space for accommodating additional components or transporting fluids. Most recently developed soft are driven by pneumatics, hydraulics, tendons. Each these has limitations including complex fabrication, integration, nonuniform strain. Here, we...
Smart shape-changing materials can be adapted to different usages, which have been leveraged for dynamic affordances and on-demand haptic feedback in HCI. However, the applicability of these is often bottlenecked by their complex fabrication challenge programming localized individually addressable responses. In this work, we propose a toolkit designing fabricating programmable morphing objects using off-the-shelf epoxies. Our method involves varying crosslinker epoxy resin ratio control...
Robot and mechanism designs inspired by the art of Origami have potential to generate compact, deployable, lightweight morphing structures, as seen in nature, for applications search-and-rescue, aerospace systems medical devices. To folding these origami-inspired designs, previous work has demonstrated several actuation methods (e.g. pneumatics, electrical motors, artificial muscles). However, it is challenging obtain self-folding machines that patternable, reversible, made with a scalable...
Robots composed of soft materials can passively adapt to constrained environments and mitigate damage due impact. Given these features, jumping has been explored as a mode locomotion for robots. However, mesoscale robots, lightweight compact actuation are required. Previous work focused on systems powered by fluids, combustion, smart materials, electromagnetic, or electrostatic motors, which require one more the following: large rigid components, external power supplies, components specific,...
Recent work has used self-folding origami inspired composites to produce complex, scalable, affordable, and lightweight morphing structures [1]. These characteristics are of interest for engineering applications, in fields including aerospace [2] medical devices [3]. Due these advantages, research on smart grown, with a particular focus the use laminate manufacturing techniques that stack layers heterogeneous materials generate functional composites. Previous this approach manufacture robots...
We present FlexTure, a method for creating pop-up kirigami structures with selectively bonded bilayer. These surfaces enable new design space accessible and rapid prototyping of dynamic surfaces. Using flexible material attached to stretched substrate, we can create metamaterial that change texture. The tactile aesthetic effects these be tuned through the configuration cuts in top layer material, as well selection layers themselves. provide workflow methods achieve target experimentally...
The designs of origami-and kirigami-inspired robots enable configurations from 2D to 3D shapes, lightweight systems, and take advantage rapid fabrication techniques. These features have been explored for robotics in applications ranging aerospace medical devices. However, achieving reversible reconfigurations that sustain/lock between shapes without requiring constant energy input allow system integration (e.g., sensing, assembly) is challenging. This letter proposes a design approach uses...
