This paper provides an overview of a new mechatronic loudspeaker system: speaker.motion. The system affords automated positioning of a loudspeaker in real-time in order to manipulate the spatial qualities of electronic music. The paper gives a technical overview of how the system’s hardware and software were developed and the design criteria and methodology. There is discussion of the unique fe...

In this paper we present new design approaches for the positional accuracy improvement of the 4-DOF parallel manipulator PAMINSA. The particularity of this manipulator is the decoupling of displacements in the horizontal plane from its translation along the vertical axis. The positioning errors caused by the inclination of the platform relating to the base are cancelled by means of two differen...

Moving GNSS towards indoor positioning is an important challenge. Increases in receiver sensitivity, the forthcoming increase in number of GNSS satellites and signal design improvements all contribute to addressing this challenge. Another remaining issue for GNSS-based indoor positioning is the impact of signal multipath phenomena in indoor environments. We designed an measurement campaign with...

Abstract − A new cutting device driven by an enlargement mechanism with a PZT drive has been developed to realize positioning the cutting tool from nm to mm. In this study, the mechanical principal of a newly developed enlargement mechanism consisting of fluid chamber, a PZT device, and cutting tool stage is reported. The basic performances of the developed mechanism are also evaluated. This de...
