Abstract

See full text

Pneumatic soft actuators, and methods and machines capable of modifying their performance and mechanical characteristics. Such a pneumatic soft actuator can be used to connect mechanical components and include an inflatable pouch formed by an airtight, flexible, non-stretchable membrane. The inflatable pouch has oppositely-disposed ends adapted to couple to the mechanical components, and has two lateral edges in which symmetrical folds are formed and define end geometries at the ends of the inflatable pouch. Inflation and deflation of the inflatable pouch increases and decreases, respectively, a distance between the ends of the inflatable pouch to induce relative motion between the mechanical components coupled to the ends of the inflatable pouch.
