Complex motions for simple actuators

An extra node (yellow) that pops in or out if a certain amount of negative or positive pressure is supplied gives this origami-inspired building block bistability. By combining these building blocks, researchers built an actuator that can bend, twist and move in complex, distinct ways from a single source of pressure. Credit: Bertoldi Lab/Harvard SEAS

Inflatable soft actuators that can change shape with a simple increase in pressure can be powerful, lightweight, and flexible components for soft robotic systems. But there’s a problem: These actuators always deform in the same way upon pressurization.

To enhance the functionality of soft …
