Cephalopod‐Inspired Swimming Robot Using Dielectric Elastomer Synthetic Jet Actuator

Abstract

In this cover image, Hualing Chen and co-workers, article number 1901130, present an underwater robot utilizing the synthesis jet actuation. As inspired by the cephalopod animal, i.e. octopus, the robot employs a soft artificial muscle actuator with specific study on achieving jet propulsion. Two modes of locomotion, swimming beneath the surface by jetting water and sailing on the surface by jetting air, are recorded, showing a new strategy of underwater robot.
