"MAVs should be thought of as aerial robots, as six-degree-of-freedom machines whose mobility can deploy a useful micro payload to a remote or otherwise hazardous location where it may perform any of a variety of missions, including reconnaissance and surveillance, targeting, tagging and bio-chemical sensing."

* The expression originates from the Book of Daniel, Chapter 5, from the handwriting on the wall that was witnessed at a banquet hosted by King Belshazzar. As those at the feast profaned the sacred vessels pillaged from the Jerusalem Temple, a disembodied hand appeared and wrote on the palace wall the words, "Mene, Mene, Tekel, Upharsin." The visionary Daniel was summoned and interpreted this message as the imminent end for the Babylonian kingdom. That night, Belshazzar was killed and the Persians sacked the capital city.
