Project
Project description
The livMatS Demonstrator project aims to build three lines of demonstrators, which are supposed to perform simple decision-making. My aim is to develop mechanisms that enable this decision-making through stimulus-response-systems, which I will implement on the material level. Since this requires the rapid prototyping of complex geometries, I am currently constructing a multi-material 3D-printer capable of combining up to eight substances.
Project outcomes
In my work, I designed a tool-changing multi-material 3D printer and used it to research components for pneumatic soft robotics. A particular focus here, in addition to air-driven actuators, was on electronics-free logic devices. These are capable of switching binary signals on a pneumatic basis and mimicking the function of electrical logic gates. Based on these components, several electronics-free compliant machines were implemented as part of my work, highlighting their potential for livMatS and the further development of 3D-printed soft robotics.
