Abstract (technical / expert description):

The aim of the research project is to provide the basis for a new generation of robotic solutions through the use of Dielectric Elastomer Actuators (DEA) as artificial muscles, covering a broad range of applications from intrinsically safe service robots to highly dynamic mobile kinematics to bionic prostheses. For this purpose, the subareas of automated production of actuators, control electronics and simulation are considered in more detail. On the basis of the aerosol jet printing, a process can be qualified which produces additive and planarized dielectric elastomer actuators and sensors. In the field of power electronics, a simultaneous evaluation and control of DEA based on a central energy source is being developed. This allows the use of multiple DEA as self-sensing actuators. An electromechanically coupled simulation model allows the investigation and optimal control of robotic kinematics that are driven by artificial muscles.
