[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.
