On a test run on Telegraph Avenue, a busy retail street near the UC Berkeley campus, Paulos controls the ProP (Personal Roving Presence) from a short distance away, via a remote link. One amused man in a wheelchair even stops and asks it for a light. Berkeley graduate student Eric Paulos describes his (PRoP) as "a simple, inexpensive, Internet-controlled, untethered tele-robot that strives to provide the sensation of tele-embodiment in a remote real space." Berkeley, CA. From the book Robo sapiens: Evolution of a New Species, page 169.
