This machine can mix up to six liquid ingredients, which allows for a wide range of cocktails. The user can decide which bottles to use in order to accommodate their drinks of choice. One could also expand Schwartz’s design to include additional bottles if they want more cocktail options. The only downside is that the bottles aren’t cooled and there is no automatic ice dispenser, so users have to fill their glass with ice by hand. But BoozeBot takes care of all of the hard work of mixing cocktails in the correct parts.

BoozeBot is a bartending, drink-mixing, cocktail-making robot! Load the machine with ingredients of your choice, select a cocktail from the list shown on the touchscreen, and watch as BoozeBot dispenses the right amount of each required ingredient into your glass.

Six peristaltic pumps, controlled by an ESP32 microcontroller, are turned on and off at precise times to move ingredients directly from their bottles, out the dispenser nozzle, and into your glass via food-safe flexible tubing. The ESP module communicates with a cheap android tablet running a react-native app that displays the menu to the user. The app also allows for direct manual control of the pumps (which is useful for cleaning).

The VK-01 Off-World Bartender is the coolest looking cocktail robot we’ve ever seen, and we’re sure it makes some pretty tasty drinks, too.

Every year, San Francisco’s DNA Lounge hosts the Cocktail Robotics Grand Challenge. This annual event exists solely for makers to show off their robotic bartending machines, and is basically a Maker Faire for the kinds of people who enjoy a nice labor-free adult beverage. Exhibitors are free to express their creativity, so long as their creations are capable of automatically making alcoholic drinks.

While this year’s event was canceled due to COVID-19, Bell decided to go ahead and assemble another machine anyway. The result is this VK-01 Off-World Bartender inspired by Blade Runner.
