We have seen some attempts at cocktail robots before, but none that look as good as this one. And this is the first one to operate on a large scale in such a public space. Installed in Singapore's Changi airport by a company called Makr Shakr, this mix bot is currently serving free drinks in the duty free areas of terminals 2 and 3. Drinkers can choose from hundreds of drinks and 150 bottles, and can even create their own cocktails. Then you can watch as the bot-tender shakes your martini and even thinly slices a lemon garnish.
