Buckling Pneumatic Linear Actuators Inspired by Muscle

The mechanical features characteristics of biological muscles are difficult to reproduce completely in synthetic systems. We describes a new class of soft pneumatic structures (VAMPs, or vacuum-actuated muscle-inspired pneumatic structures) that combine actuation by negative pressure (vacuum), with cooperative buckling of beams fabricated in a slab of elastomer, to achieve motion and demonstrate many features that are similar to that of mammalian muscle.
