Pneumatic Networks for Soft Robotics that Actuate Rapidly
Bobak Mosadegh,Bobak Mosadegh,Panagiotis Polygerinos,Christoph Keplinger,Sophia W Wennstedt,Robert F. Shepherd,Unmukt Gupta,Jongmin Shim,Katia Bertoldi,Conor J. Walsh,Conor J. Walsh,George M. Whitesides,George M. Whitesides +12 more
TL;DR: In this article, a pneumatic actuator can bend from a linear to a quasicircular shape in 50 ms when pressurized at Δ P = 345 kPa.
Journal ArticleDOI
Flexible mechanical metamaterials
TL;DR: In this article, the design principles leading to these properties are identified and discussed, in particular, linear and mechanism-based metamaterials (such as origami-based and kirigami based metammaterials), harnessing instabilities and frustration, and topological and nonlinear metam materials.
Journal ArticleDOI
A 3D-printed, functionally graded soft robot powered by combustion
Nicholas W. Bartlett,Nicholas W. Bartlett,Michael T. Tolley,Johannes T. B. Overvelde,James C. Weaver,Bobak Mosadegh,Katia Bertoldi,George M. Whitesides,George M. Whitesides,Robert J. Wood,Robert J. Wood +10 more
TL;DR: Using three-dimensional printing to fuse together multiple materials to manufacture a combustion-powered robot whose body transitions from a rigid core to a soft exterior, which is able to perform untethered jumping and also enhances performance.
Journal ArticleDOI
Negative Poisson's Ratio Behavior Induced by an Elastic Instability
TL;DR: Negative Poisson's ratio behavior has been uncovered in cellular solids that comprise a solid matrix with a square array of circular voids that results from an elastic instability, which induces a pattern transformation and excellent quantitative agreement is found between calculation and experiment.
Journal ArticleDOI
Modeling of Soft Fiber-Reinforced Bending Actuators
Panagiotis Polygerinos,Zheng Wang,Johannes T. B. Overvelde,Kevin C. Galloway,Robert J. Wood,Katia Bertoldi,Conor J. Walsh +6 more
TL;DR: This study provides a set of systematic design rules to help the robotics community create soft actuators by understanding how these vary their outputs as a function of input pressure for a number of geometrical parameters.
