Negshell casting: 3D-printed structured and sacrificial cores for soft robot fabrication.

PloS one
Soft robot fabrication by casting liquid elastomer often requires multiple steps of casting or skillful manual labor. We present a novel soft robotic fabrication technique: negshell casting (negative-space eggshell casting), that reduces the steps re...

Maximal Performance of an Antagonistically Coupled Dielectric Elastomer Actuator System.

Soft robotics
Dielectric elastomer actuators (DEAs) have been shown to produce electrically induced strains beyond 500%. The ability to undergo large deformation allows the DEA to store large amounts of elastic energy by electrical actuation; it also allows the DE...
