Multiple-degree-of-freedom motion data transmission using audio signal and its application in a presentation robot system

Employing an audio signal as a data carrier, we study a wired data transmission method for a multi-degree-of-freedom robot. In this paper, we propose a frequency division multiplexed amplitude modulation method and its demodulation parameter design method to minimize the processing time. To verify the proposed method, an experimental system is implemented on a single PC with a 3DOF robot. As a practical application, a presentation robot system synchronized with a slide show in PowerPoint is introduced.
