A high-deformation electric soft robotic gripper via handed shearing auxetics
… robotic actuators built from handed shearing auxetics (HSAs). Soft robots - robots made out of more compliant materials such as rubber and silicone - are significantly more robust and safer than their rigid-bodied counterparts due to their intrinsic compliance. However, existing soft robots …

Vision-based Proprioceptive and Force Sensing for Soft Robotic Actuator
… interiors of actuators based on handed shearing auxetics (HSA) to record their deformation. Using external motion capture data as ground truth, we train a convolutional neural network (CNN) that maps the visual feedback to the pose of the actuator’s tip. Our model provides predictions of tip pose …

Experimental and Numerical Study of Ductile Metal Auxetic Tubular Structures
… based on their geometric configuration. Cellular auxetics are light-weight and cost-effective materials that have the potential to demonstrate high strength and resilience under axial forces. Existing research on metallic auxetics is scarce and based mostly on analytical studies. Apparent NPR …

Function Follows Form: An Exploration of Robotic Embodiment through Geometry
… When complex metamaterials (ex. handed shearing auxetics) are sensorized, fully proprioceptive soft robotic systems can be created as structure, actuation and sensing are embedded into one single geometry. These examples demonstrate not only the power of using geometry as a design tool, but also …

Simulation informed design of stimuli responsive structures and higher-order assemblies in DNA nanotechnology
Nanoscale structures can be manufactured using a top-down or bottom-up approach. Top-down techniques fabricate a desired structure by imposing an external source of order (such as specific patterns of light in photolithography). This contrasts with bottom-up approaches, which exploit molecular …

A kinetostatic conceptual framework to design deformable mechanical metamaterials
"Mechanical metamaterials have been gaining much interest in the field of material design for their unique attributes such as light weight, high strength, enhanced energy absorption, high impact, and fracture resistance. The behavior of such materials is governed by their structural geometry rather …
