Development of new robot arm using artificial muscle driven by EHD pump without mechanical drive unit

Abstract

We developed new pump named EHD pump which has no mechanical drive unit and this pump used the EHD phenomenon. The EHD (electro-hydro-dynamics) phenomenon is a phenomenon which generates the flow in insulation fluid by applying a high voltage electric field. We are developing new robot arm using artificial muscle driven by EHD pump. In this study, new robot arm which used EHD pump as the frame was made as a trial production, and that evaluation was done.
