"Octothorphe" sounds like a good robot name...
"The term octothorpe was coined by engineers at Bell Laboratories in the early 1960s, who wanted a name for one of two non-number function symbols on the first touch-tone keypads (the other was the *, which they called a sextile). It didn't catch on, and the # key became famous as an ineffectual way of interacting with the robots who work at your bank."
