A power generation circuit and process for providing electrical power and data transfer by means of a module attached to the audio port of a mobile electronic device. The method includes generating first social network data based on the relationship between the first party and each of the one or more additional parties. The power line interfaces contain at least one unique identifier to distinguish the interface and its associated network device from other devices on the same network and thereby enable device message exchange. The robot tool is manipulated into the tool contact point.
