Friday Fun: Party robot bartender

Bartenders beware: A robotic drink-dispensing rig is aiming to steal your customers while pouring cocktail creations at the push of a touchscreen button. This Open Source Robot Bartender Pours the Perfect Mix article tells about bartender robot that the creators call Bartendro: Operated through an iPad interface, this device holds up to 15 bottles of beverage plumbed into custom-designed, Raspberry Pi+microcontroller-controlled peristaltic pumps.

As simple as the concept seems it’s actually the result of a lot of R&D. But the designers say that the software testing has never been more fun: Drink Testing Gets You Drunk.

Partyrobotics page has more information on the robot, including a video. The designers have raised funds to put the Bartendro into production. The system uses open source hardware and software.

    Robotic bartender assembles personalized drinks, monitors alcohol consumption, and takes social mixing to a whole new level

    The ‘mixology system’ tracks your order from start to finish: a large display behind the bar shows you the number of drinks ahead of yours in the queue, the current wait time, and lets you know when your drink is ready to be picked up. It also shows you what’s popular to drink tonight among both the ladies and the gents in the crowd, and lets you influence drinking trends in realtime by incorporating your suggested tweaks on popular recipes.

    Makr Shakr is one of MIT’s SENSEable City Lab projects, where the goal is to study and anticipate how sensor technologies can inform and transform our built environments. The project’s creators say that it’s not about trying to replace bartenders with robots, or even about drinking; it’s about exploring the dynamics of consumption and social networks in the context of sensor and digital fabrication technologies. In other words, its a mini-lab for learning about how we, the social creatures that we are, might interact with each other and our environments in the sensor-augmented cities of tomorrow.

    “Drinking happens to be a very social activity,” Turgeman said. “At a bar, you’re looking to meet people. You might think ‘hey that’s a great drink I just invented’ and want to share it or iterate on it … by exploring the realtime behavioural dynamics in this situation, maybe we can learn something about how people interact with and influence each other’s consumption habits.”

    Roboxotica (Barbot Festival in Vienna)

    Just this past week was this year’s Roboexotica 2013! The annual event was the world’s first and is perhaps the finest festival of cocktail serving robotics out there!

    Founded 15 years ago in San Francisco, Roboexotica brings together scientists, hackers, and artists from all around the world to build the most awesome drink dispensing technologies. It’s also an opportunity to discuss innovation, science fiction, and the world of robotics to come — after utilizing some of the robots of course!

    Barbot Mixes Drinks Perfectly with Web Interface

    Are you good at mixing drinks? We think this Barbot might give you a run for your money!

    Not only does this Barbot have room for 5 different liquors, but you can combine them any way you want with an extremely slick web interface that you can check out for yourself.

    The hardware behind this build is a BeagleBone Black running Ubuntu 13.04 with Apache2, MySQL, and PHP to host the web interface — bind and DHCP are used to create the web portal using a USB WiFi dongle. The online interface directly controls the pumps using PHP via the GPIOs.

    Make me a Drink, Drinkmo.

    [Cabe Atwell's] latest project is a work of art. Let us introduce the Drinkmotizer: a Raspberry Pi Drink Mixing Robot.

    As [Cabe] says, almost every engineer has a drink-mixing robot on their project todo list. We’d probably have to agree; they’re functional, cool, and useful at parties.

    The Drinkmotizer – a Raspberry Pi Drink Mixing Robot
    Posted by Cabe Atwell in Raspberry Pi Projects on Jan 18, 2014 12:52:54 AM–aka-the-drinkmotizer

    “Make me a drink, Drinkmo.”

    On every engineer’s senior design short list is/was a drink mixing robot. One of the few projects that’s fun at parties. You want the Drinkmotizer at your party… You need the Drinkmotizer at your party… At some point, dexterity for drink mixing is lost at a gathering. Drinkmo is your designated, sober, mixologist. Your enabler. Your friend.

    I know what you are thinking, “hey, there are other drink mixing bots out there, what makes this one different?” This one doesn’t break the bank. It’s DIY, Open, expandable. Artistically speaking, It isn’t just a nozzle that sprays alcohol at objects, it uses the actual bottle, and gravity.

    Here were my requirements of

    - Use the original drink bottles
    - Be expandable
    - Single button interface
    - Be inexpensive (relatively to the other bot options)

    Barobot Serves Cocktails While Using Open Design the Right Way

    Oh for the day when we can stop repeatedly looking up our favorite drink recipes on Wikipedia. Those may be just around the corner and you’ll have your choice of single-click delivery or toiling away in the workshop for a scratch build. That’s because Barobot is satisfying both the consumer market and our thirst for open hardware goodness. They’re running a Kickstarter but to our delight, the software and mechanical design files are already posted.

    Margarita Drip Infuser Ensures a Perfect Mix

    n order to get a margarita just right, the various ingredients need to be mixed together quite vigorously to over-come the different viscosity of the fluids. Looking to create his own barbot of sorts, [TVMiller] decided to make a Margarita Drip Infuser to help make margaritas a bit easier.

    Using various chem lab supplies, [TVMiller] has cobbled together something pretty awesome. The Infuser can take up to 8 different ingredients into its test tube reserves, and after the drink ingredients are programmed on the computer, the magic begins.

    Margarita Drip Infuser
    Drop by drop to a smoother cocktail

    A semi-traditional Margarita pour requires vigorous agitation in an attempt to blend the varying viscosity fluids constructing the cocktail. As an alternative, less abusive and theoretically smoother method, we affixed an Arduino Uno to an 8 channel relay controlling 8 solenoids to drip each ingredient, of any varying recipe, one drop at a time; allowing the blend to occur in real time. The glass is held in a copper wound that a coolant fluid is pumped through. Forgive the impoverished components, both mechanical and delicious.

    HardWino Takes The Effort Out of Happy Hour

    A personal bartender is hard to come by these days. What has the world come to when a maker has to build their own? [Pierre Charlier] can lend you a helping hand vis-à-vis with HardWino, an open-source cocktail maker.

    The auto-bar is housed on a six-slot, rotating beverage holder, controlled by an Arduino Mega and accepts drink orders via a TFT screen. Stepper motors and L298 driver boards are supported on 3D printed parts and powered by a standard 12V DC jack.

    Barbot is an open source Arduino cocktail mixing robot controlled with the hybrid mobile app via Bluetooth.

    The Barbot has been designed to hold up to 9 bottles of ingredients for making the cocktails, dispensing the correct amount from each to mix your cocktail of choice.

    Cocktails can be chosen using the mobile app (available for iOS and Android) that connects to the Barbot via Bluetooth.

    Open Source Barbot Needs Only Two Motors

    Most drinkbots are complicated—some intentionally so, others seemingly by design necessity. If you have a bunch of bottles of booze you still need a way to get it out of the bottles in a controlled fashion, usually through motorized pouring or pumping. Sometimes all thoe tubes and motors and wires looks really cool and sci fi. Still, there’s nothing wrong with a really clean design.

    [Lukas Šidlauskas’s] Open Source Barbot project uses only two motors to actuate nine bottles using only a NEMA-17 stepper to move the tray down along the length of the console and a high-torque servo to trigger the Beaumont Metrix SL spirit measures. These barman’s bottle toppers dispense 50 ml when the button is pressed, making them (along with gravity) the perfect way to elegantly manage so many bottles. Drink selection takes place on an app, connected via Bluetooth to the Arduino Mega running the show.

    Trinket Chills Your Drinks

    Who wants warm drinks? Well, coffee drinkers, we guess. Other than them, who wants warm drinks? Tea drinkers, sure. How about room temperature drinks? No one, that’s who. It’s silly to buy a refrigerator to cool down a single drink, so what option are you left with? Ice cubes? They’ll dilute your drink. Ice packs and a cooler? Sure, they’ll keep your drinks cold, but they’re hardly cool are they? No, if you want a cold drink the cool way, you build a thermoelectric cooler. And if you want to build one, you’re in luck, because [John Park] has a tutorial to do just that up on AdaFruit.

    The device is capable of mixing three liquids, which in GreatScott’s case consist of vodka, cranberry juice, and grapefruit juice (also known as a Sea Breeze), in a drink size selected via a rotary encoder and LCD screen.

    An Arduino Nano provides the brains for this operation, and each component is poured using a series of three peristaltic pumps. Meanwhile, a load cell underneath the glass holder ensures that the correct amount of liquid is dispensed.

    Beautiful Pi-Powered Cocktail Machine

    Science fiction has long had the idea that a good drink should just appear from a sliding panel in a wall. Bartending is to be the preserve of robots and AIs – manual control is for the past, and in an effort to continue our progress to towards that sci-fi future, Reddit user [HighwingZ] has built a beautiful machine that mixes and serves drinks.

    Over the past few years, Reddit user [callingyougoulet] has created Boozer, a DIY beer dispenser that keeps track of how much of your brew you have left in your kegs.

    Inside the freezer is the Raspberry Pi and four flow sensors, each one connected to a GPIO port on the Pi. After some calibration, the Python code running on the Pi can calculate a pretty close estimate of the amount of liquid poured. There’s also a temperature sensor in the freezer, so that you can tell how cool your beer is.
