Andreas Hepp is Professor for Media and Communications at the ZeMKI (Centre for Media, Communication and Information Research), University of Bremen, Germany. In his 2020 article[^paper], mentioned in the introduction to this chapter, he distinguishes three kinds of *communicative bots*: artificial companions, social bots and work bots. For Hepp, communicative bots are characterised through a double embodiment: a *communicative embodiment*, referring to the bots' human-like representation, and an *infrastructural embodiment*, referring to the bots being embedded in the materiality of the infrastructure on which they are active.
