I make robots that are soft and floppy. If you can change your shape, you can go anywhere—you can squeeze through small holes in a rubble field and navigate unstructured terrain like forests. The problem is that if you’re soft, you’re slow, because when you push against something, your body deforms rather than creating forward motion. So we looked to the caterpillar as a model.
