Abstract
In revisiting the Principles of Robotics — as we do in this special issue — it is important to carefully consider their full meaning. The meaning of communication depends both on the context in which that communication is embedded and the author’s intent. Here I address first the meaning of the document as a whole, then of its constituent parts. I address this as one of the experts invited to the EPSRC robot ethics retreat, and present at the Principles’ conception.
