Mathematics of sea slug movement points to future robots

Mathematicians recently discovered a lot of new, powerful geometries involved in frilly surfaces. They developed the mathematics to describe these surfaces — inflected nonsmooth surfaces, which change the direction in which they bend — and the combination of new geometry insights and age-old slugs might just be the right combination for a new generation of flexible, energy-efficient soft-bodied robots.
