Abstract

Conventional robots usually use heavy rigid components, such as engines, gearboxes and linkages that are made of high-density materials. Although they can perform complex movements and processes, they are typically not able to perform movements similar to those of living animals. Dielectric elastomer (DE) actuators,  in contrast, allow animal-like behavior of soft robots with large natural strokes. However, these advantageous features are often limited by the requirement for modulated high voltage signals and connected bulky and expensive electronics.

We present a novel approach to integrate charge control, external sensing and high voltage signal processing into DEs. Since all necessary electric components are integrated and only consist of common DE materials, such as polymer membranes and carbon grease,  soft robots developed using this approach are self-controlled and do not need any conventional, external electronics. The biomimetic structures only need constant direct current to supply suitable charge to the functional components.

We show our latest developments like crawling electronics-free robots, concepts for flying robots and concepts for dielectric high voltage Boolean logic. Furthermore, we give an overview of a joint project with TU Dresden that will develop these laboratory processes to modern mass production scale technologies.
