Abstract

Small animals, such as worms, snails, and insects use interfacial phenomena to propel and perform locomotion. These phenomena emerge at the liquid–air, solid–liquid, and liquid–liquid interfaces. With robots becoming smaller and lighter, interfacial phenomena become central in their design, and withhold potential solutions for adhesion, locomotion, and dynamic transitions between environments.
