A cocktail dispensing robot. Controlled over the Internet or a local WIFI network, it is capable of mixing a variety of drinks from up to five different ingredients.
The device is based on a BeagleBone Black with a USB WIFI adaptor. The BeagleBone takes inputs from 5 sets of switches, one to toggle the pumps and another to select the direction of flow, which allow the user to prime and purge the pumps. The pumps are standard peristaltic pumps which are driven by a H bridge for direction control. The control buttons and pumps are all set in a laser-cut plexiglass control panel. The control panel and other plywood panels are all mounted on a sturdy angle iron frame.
