Universal robotic gripper based on the jamming of granular material
Eric Brown,Nicholas Rodenberg,John R. Amend,Annan Michael Mozeika,E. Steltz,Mitchell R. Zakin,Hod Lipson,Heinrich M. Jaeger +7 more
TL;DR: It is shown that volume changes of less than 0.5% suffice to grip objects reliably and hold them with forces exceeding many times their weight, and opens up new possibilities for the design of simple, yet highly adaptive systems that excel at fast gripping of complex objects.
Journal ArticleDOI
A Positive Pressure Universal Gripper Based on the Jamming of Granular Material
TL;DR: A simple passive universal gripper, consisting of a mass of granular material encased in an elastic membrane, that can rapidly grip and release a wide range of objects that are typically challenging for universal grippers, such as flat objects, soft objects, or objects with complex geometries is described.
Proceedings ArticleDOI
JSEL: Jamming Skin Enabled Locomotion
TL;DR: A new paradigm in soft robots is presented that utilizes jamming of a granular medium and the concept of activators (as opposed to actuators) is presented to jam and unjam cells that modulate the direction and amount of work done by a single central actuator.
Journal ArticleDOI
Particle shape effects on the stress response of granular packings
Athanasios G. Athanassiadis,Marc Z. Miskin,Paul Kaplan,Nicholas Rodenberg,Seung Hwan Lee,Jason Merritt,Eric Brown,John R. Amend,Hod Lipson,Heinrich M. Jaeger +9 more
TL;DR: It is found that particle shape controls the details of the stress-strain curves and can be used to tune packing stiffness and yielding and identify trends among the various shapes that allow for designing a packing's aggregate behavior.

Particle Shape Effects on the Stress Response of Granular Packings
Athanasios G. Athanassiadis,Marc Z. Miskin,Paul Kaplan,Nicholas Rodenberg,Seung Hwan Lee,Jason Merritt,Eric Brown,John R. Amend,Hod Lipson,Heinrich M. Jaeger +9 more
TL;DR: In this article, the authors present measurements of the stress response of packings formed from a wide range of particle shapes, including convex shapes such as the Platonic solids, truncated tetrahedra, and triangular bipyramids, as well as more complex, nonconvex geometries such as hexapods with various arm lengths, dolos, and tetrahedral frames.
