Building a Tic-tac-toe Playing Robotic Arm

The aim of this paper is to create a robotic arm with artificial intelligence to play tic-tac-toe against a human player. The robotic arm would actually place X or 0, when will be its turn. The human also places X or 0 when will be his turn. The robotic arm should have a tic-tac-toe algorithm implemented to try to beat the human player. The whole setup it a fusion of robotics, computer vision, artificial intelligence, electronics and mechanics. The main task is to beat the human player as much times as possible. The hardest part seems to be the artificial intelligence or the tic-tac-toe algorithm, but actually the mechanical building of such a robotic arm can be a challenging task too.
