This use case shows how image vision can give the normally dum robots intelligence. The robot is mounted behind a acrylic glass screen with a pencil added to his arm, and he can play against the user Tic Tac Toe.
The user must start and put the first cross with a pencil writing on the acrylic glass. The robot has a built in camera, so that his AI working form the can analyse where is cross is and give feedback in real time and react on the user, with painting his circle.
As the robot has access to large database of human behaviours he also can predict the next move of the user. After one turn the robot changes the marker for a sponge and wipes the screen clean.
