In the past few years, we have covered plenty of cool robotic cocktail makers here. The Mix Master is also worth a look. It is a tabletop automatic cocktail maker with Arduino that comes with up to 8 pumps and 12 optics (depending on the model). An Android tablet is available to control the machine.
You can use the cocktail editor on the tablet to prepare drinks. As the developers explain, everything is connected to an Arduino Nano.
