Bartendro is a modular and open-source cocktail dispensing robot!

Welcome to the future of cocktails!

What is it?

Bartendro is a precision cocktail dispensing robot! It makes tasty drinks quickly and repeatably without the mess. It's light and portable so that you can easily take it to events, conferences, weddings, parties, or wherever!

It's easy for one bot to serve more than 200 drinks in an evening.  

A tasty cocktail is less than 10 seconds away.

Bartendro is easy to set up and cleans up in about 5 minutes. Liquids only pass through food-grade tubing, not moving parts! Fill up a pitcher with warm soapy water and turn on the cleaning cycle. Run another cycle with clean water and sanitizer and the bot is good as new.

The user interface is intuitive and can be customized for the different types of events you host.

Special admin screens let you manage dispensers, ingredients and drink recipes. This is where calibration, customization and cleaning take place.

You can also view reports of the drinks made and quantities of ingredients used.

Check out one of our latest blog posts to get an idea of Bartendro's drink making capabilities.

Why did we make it?

Have you ever made or had a cocktail that was really perfect but was elusive to recreate? Have you ever wanted to know more about cocktails without drinking a lot to acquire the knowledge? We did. We wanted a machine that could pour complex cocktails in any size, including small tasters, that are proportionally accurate.

We were also fed up with precision dispensing technology being prohibitively expensive and wanted a more affordable solution that we and others could start using to make fun and interesting things.

We wanted to build a community where users could create, rate and share new drinks from around the world. 

How does it work?

We use peristaltic pumps which dispense a known volume with every revolution of the motor to precisely meter our drinks.

Each pump combined with our custom electronics is called a "dispenser." The dispenser boards use the same processor as an Arduino and connect through a RJ-45 connector to a "router board" which carries the Raspberry Pi (RPI) computer. Any normal networking cable will work, but we've custom made the cables that come with Bartendro to be just the right length. 

Router boards can handle up to 15 dispensers, while miniRouter boards can handle up to 3 dispensers. 

The RPI sets up a wireless access point and creates a WiFi network called Bartendro.

To get started, simply connect to this network from any device and go to a web browser. Regardless of the web address you type, you'll be directed to Bartendro's main drink menu screen.

What can you do with it?

Every time we set Bartendro up, we get a flurry of ideas suggested to us. Can it accept credit cards? Can you make it detect if someone is intoxicated? What about RFID or facial recognition. These are all possibilities we'd love to see implemented, but our resources are limited. That's why the software and the hardware are open source. 

Add a Microsoft Kinect to the top of the bot, or a card reader for payment or age verification, a breathalyzer, social networking or drink suggestions. Integrate stirring/shaking, an ice dispenser or a conveyor belt to move several glasses through the bot. You can even put the whole thing on wheels and make it a mobile robot! The ideas are almost endless and this is a great platform to build on. 

Check out our source code on Github.

Ideas we've received for pump uses:

  • pancake/crepe bot
  • coffee bot
  • juice bot
  • garden watering bot
  • aquarium nutrient dosing 
  • automated chemistry/biology experiments
  • recirculating pump for fast infusions
  • new foodie creations
  • beer brewing / wine making

These pumps are not to be used for medical applications, but they're good for just about everything else. Different types of tubing must be used for heavier solvents, or bio-diesels. Send us a note if you want more info.

What you get!

Stickers, t-shirts and glassware will just contain our logo unless you, our backers, vote on having something more fun like, "I love bots that get me drunk!"

Disclaimers:

The current design doesn't handle carbonated liquids well, but we see this as a solvable problem that we'll tackle in the near future. 

The quality of drinks depends on what you put in the bot. Garbage in equals garbage out. We like quality drinks, so we make simple syrup and squeeze fresh limes and lemons for every event. We think it's totally worth it.

What you see in the pictures may be slightly different than what you get. We may have to make optimizations to build much larger quantities. The final colors of the enclosure are not finalized. The black frame will remain black, but the sheet metal parts will likely be a light metallic silver.

Bartendro is not fully sealed; the electronics are intentionally visible because we think they're cool to look at. The drink-pouring action doesn't happen near the electronics, but you will still need to be careful to not get liquids on them! 

We know first hand how easy it is to get carried away when a drink can be made at the press of a button. Please drink responsibly and always have a designated driver.

Please Support Us!

We've worked very hard to get the cost as low as possible without sacrificing quality and commercial level functionality. We've also sacrificed our livers to make sure the quality of drinks in our database is excellent.

We need to place several large minimum-quantity orders and purchase expensive pieces of tooling to keep this project going. Please back us today and help us get there!

Risks and challenges Learn about accountability on Kickstarter

We have our suppliers and vendors lined up, but we've never produced large quantities yet, so quality in volume has yet to be seen.

We need to ship bots and have them show up safely at your door, but the proper protection and packaging has not been figured out yet.

FAQ

  • The current dimensions of Bartendro, which are subject to change slightly, are:

    ShotBot: 6" W x 19" H x 11" D

    Bartendro 3: 13" W x 19" H x 11" D

    Bartendro 7: 19-1/2" W x 25-1/2" H x 12" D

    Bartendro 15: 35-1/2" W x 28-1/2" H x 12" D

    Last updated:
  • Not really. The miniRouter is designed to plug into the Raspberry Pi's header, there isn't an easy way to add more pumps unless you get a full router board, which can handle 15 pumps. We'll make these available if our Kickstarter funds.

    Last updated:
  • Yes! If you are in the contiguous 48 states, we'll cover your shipping costs!

    International shipping is extra and is listed under each reward if available.

    Last updated:
  • In theory. The hardware is not limited to prevent this, but there is no software written to make this happen. We can't guarantee that this will be something we address immediately, but maybe third-party developers can help us make it available sooner.

    Last updated:
  • No. This is part of what our tooling funds go towards, and will be included in the built Bartendro 7 and 15. We want to make plastic/rubber caps that allow tubing to slip through, while covering the bottle openings. The tops cannot seal the bottles however, there will need to be a small vent hole so that when the pump begins pumping, we don't create negative pressure in the bottle.

    Last updated:
  • Yes! LEDs are an important aesthetic component of the bots and we want you to be able to tailor them to your tastes. We'll have more details and how-tos on our website soon.

    Last updated:
  • The router and miniRouter boards will be made available individually when we get funded. They will likely be bundled with the high power 24V power supplies that are needed to drive the pumps. Dispensers (pumps + electronics) will also be available. We will do our best to offer these to you at the lowest prices possible.
