Roboticists at the Rensselaer Polytechnic Institute in New York have
built a trio of robots that were put through the classic 'wise men
puzzle' test of self-awareness - and one of them passed.
In the
puzzle, a fictional king is choosing a new advisor and gathers the three
wisest people in the land. He promises the contest will be fair, then
puts either a blue or white hat on each of their heads and tells them
all that the first person to stand up and correctly deduce the colour of
their own hat will become his new advisor.
Selmer Bringsjord set up a similar situation
for the three robots - two were prevented from talking, then all three
were asked which one was still able to speak. All attempt to say "I
don't know", but only one succeeds - and when it hears its own voice, it
understands that it was not silenced, saying "Sorry, I know now!"
However,
as we can assume that all three robots were coded the same,
technically, all three have passed this self-awareness test.
