The Glaucus

The Glaucus is a soft robotic quadruped composed of a single seamless silicone part. It has a complex network of interior channels, created via a lost wax process, that turn into actuators when pressurized with air. It’s able to walk with a diagonal gait, similar to a gecko or Glaucus Atlanticus sea slug, using only two input channels.

quad_03The Glaucus was created to demonstrate a method for fabricating soft robots of nearly any geometry with arbitrary interior structures. It’s been my goal, since beginning my research into soft robotics, to simplify the process of prototyping and refining designs. Often the barrier between an interesting bench prototype and practical application is how it scales into production. If methods for experimenting with the core concepts, evaluating them in a context that represents their final manufactured state, and refining them for mass production don’t exist, the idea is very likely to languish on the bench.
