The Makr Shakr is a bartender, social sharing system, and alcohol consumption monitor in one robotic design. Designed by the M.I.T. Senseable City Lab in collaboration with the Coca-Cola Company and Bacardi Rums and produced by Italian firm Carlo Ratti Associati, the robot debuted at the Google I/O conference in May. Guests transmit their cocktail orders via the Makr Shakr app, then watch as three large, orange robotic arms mix up the prescribed combination of liquor, syrups, fruit mixers, and ice. The movements are precise enough to muddle a mojito and thinly slice a lemon. A large screen behind the bar displays a variety of stats, such as number of drinks in the queue, approximate wait time, drinks ready for pickup, and most popular spirits by gender. The app also allows users to see what type of drinks others are ordering, rate the drinks, and share photos on social networks. It also aims to promote responsible consumption by monitoring what a person orders and how often. The developers say for now Makr Shakr is a prototype, intended to be a “social experiment that looks at how people might embrace the new possibilities offered by digital manufacturing.”
