Pneumatically controlled lattices with tunable mechanical behavior [PDF]

Communications Engineering
Buckling is a common failure mode in lattice structures, limiting their use in some applications. The tendency of a strut to buckle is related to the local nodal connectivity. In this work, we introduce a pneumatic actuation strategy to actively tune the

Soft, Rotating Pneumatic Actuator [PDF]

Soft Robotics, 2017
This article describes a soft pneumatic actuator that generates cyclical motion. The actuator consists of several (three, four, or five) chambers (arranged around the circumference of a circle surrounding a central rod) that can be actuated independently using negative pressure (or partial vacuum).
