From raspberry pi pod:
Junya Sakamoto wanted a little help with the later levels of Puzzle & Dragons (which is big in Japan). So he added a Gertbot to his Raspberry Pi and then hooked up some motors and a rig to allow the Pi to press the touch screen of his iPhone. He then created a program to scan the game ‘board’ and then work out the best moves to make, which the Pi interprets as commands for the motors.
