Students from the Florida International University have completed their Arduino based Bartender project. A computer has the menu of drink items, there are 6 solenoids that are controlled by the arduino. The 6 solenoids are able to dump certain drink options. There is a sensor that makes sure a cup is in place before the drink is poured. The system is able to mix a large variety of drinks with the 6 ingredients that it has available. You can see the final version above and the video of the prototype below. It looks like quite a few things have changed from concept to completion.
