Comments

It's called the Glaucus, after the blue sea slug Glaucus Atlanticus. It has hollow interior chambers that interdigitate with one another. When either of these chambers is pressurized it deforms and bends the structure of the robot. This bending produces the walking motion. It is similar to how a salamander walks, by balancing itself on one pair of legs diagonal from one another while moving the opposite pair forward.

The Glaucus is a proof of concept for a method developed here that can reproduce nearly any geometry modeled on the computer as a seamless silicone skin. It is hoped to apply these same techniques to practical problems in medicine and engineering as the technology develops.
