[Nick] just finished up bis barbot build that is named after our favorite bartender. It’s an impressively capable even if it was done on the cheap.
The user chooses a libation for iZac to make via an Android tablet. This drink is interpreted by an Android ADK to have the mechanics of the robot swing into action and start making a drink.
The part of the build that moves the fluid was inspired by the Evil Mad Scientist Labs’ Drink Making Unit 2.0. Instead of pumps pulling the liquid through tubing, [Nick] attached an aquarium air pump to an Erlenmeyer flask. A siphon tube draws liquid out of the flask because of the difference in air pressure. The liquid is controlled by a few laser cut pinch valves that he designed.
Once a user selects a cocktail, the robot swings into action and dispenses liquid into a glass sitting on a load cell. Since the glass is being weighed at all times, iZac knows exactly how much alcohol (and in what proportion) is in the cocktail. [Nick] tested out iZac at the Sydney Hackerspace with soda water and flavoring. iZac proved very popular and we’re wondering if we could build something like this in a liquor cabinet.
[John Creswell] built a heck of an automatic bartender in a kitchen island. The image on the left shows a top-down view of the inside of the cabinet. There’s a mini-fridge where the liquids are stored, and around the perimeter of the cabinet [John] mounted sixteen pumps to get the beverage up into your cup. Drinks are dispensed from the lighted serving fixture on the right by selecting your preferred cocktail from a computerized menu. According to his writeup the project was finished about five years ago, making us wonder if he’s tackled any upgrades such as adding support for smartphones.
The friendly robotic bartender we’ve covered a couple of times before hit the airwaves last week. [Jamie], the inventor of Bar2d2 sent in a link to video of the barkeeper in action. The story runs from 0:30-4:40 and covers a bit about the build, the conversion to automatic drink mixing, and plenty of happy liquor-guzzling party goers.
We get a good look at the drink ordering interface called Lazy Drinker. It runs on a laptop and communicates wirelessly with Bar2d2. Looks like you can get your hands on the software for free but the hardware, either in kit form or assembled, is going to cost you. Want to see how the dispenser kits are put together? Don’t miss the illustrated assembly instructions.
[Jamie Price] directed us to this photostream of the build for Bar2D2. Though it isn’t the first bartender bot we’ve covered. It very well could be the best executed. Bar2D2 can travel around the party dispensing bottles of beer, shots, and even cans. The construction looks fantastic. You can follow along in the photostream from the very beginning. It is currently radio controlled and can party for about 8 hours per charge. The next planned upgrade is a system that allows you to choose a mixed drink from a database and Bar2D2 will mix it up.
As you can see from the pictures, Bar2D2 is the life of the party, attracting pretty girls and cheesy sci-fi tv pirate astronauts too.
We love beer and we love robots, so guessing how we feel about this robotic bartender should be a no-brainer. Known as Mr. Asahi, the robot opens bottles and pours beer while taking your orders with aplomb and a jovial British accent. It also has a customized lazy susan with slots for bottles and notches for the robot’s hand to grasp.
Amazingly, this is not Asahi’s first beer pouring robot. That one requires you to do most of the leg work, though, so this one is a marked improvement. Best of all, it won’t ignore you when a person more attractive than you comes into the bar, and it won’t snub you for leaving a lousy tip. We now fear alcohol fueled robot rampages… they get more human every day. Video after the break.
