(Phys.org) --Students at Carnegie Mellon University in Pittsburgh have created a Scrabble-playing robot who is quite remarkable, not because it plays well but because it does not play well, and talks with all the human signs of a sneering winner and a sore loser. This robot is Victor, who has been sitting in the school's computer science lounge playing Scrabble with any human who can accommodate Victor's jokes and jibes.
