A cocktail robot is exactly what you would expect it to be: an automated device that can mix drinks for you on command. And believe it or not, my final project for my senior microcontroller class in college was a cocktail robot. The project was a complete disaster! In hindsight, it's very possible that more time was spent sampling the product than working on the project. The final demonstration didn't go well at all. In fact, whenever you exclaim "Oh Sh*t!" during a recorded final demonstration, things aren't going very well...at all. However, for some reason, the professor generously gave us a passing grade.
Anyway, I was reminded of this project when I came across an online story of a similar project (although considerably more creative... and working). Apparently, there is quite a community out there that builds these types of projects. In fact, there are several annual competitions to demonstrate your robotic (and possibly drinking) chops.
So anyway, you absolutely need to check out the cocktail robot that was created by the folks over at Evil Mad Scientist Laboratories. Pay close attention to the devices they used to pump the ingredients! Funny! The fact that they are making white russians with the robot makes it even better!

"White Russian? Coming right up, heavy on the irony!"
