The Arch section quickly agreed alcohol was the only answer to "What machine should we make"
After a couple hours of discussion, we decided on a basic concept and divided the tasks betweeen hardware, software, rack, and pouring mechanism.
To pour the different liquids from different resevoirs into the target cup, the mechanism team tried out several passive pour mechanisms.
They tried a "hamster" drip method in which pushing up on a water stop would allow water to flow.
They tried a syringe injection method.
They settled for a simple method of adjusting the height the alcohol resevoirs and allowing gravity to pull the liquid into the target cup.Your browser does not support the video tag.
The rack team was tasked with designing something to hold the alcohol and the recieving cup. Over the course of several weeks the rack slowly took form beginning with CAD, laser cutting a prototype, making alterations, milling a full scale rack, and then a series of improviations to secure the motor to the spinnning tray.
The software team came out of a mix of several different teams. In the end came down to those doing the backend programming to move the alchohol tray up and down and to spin and a team that built the frontend interface for people to order a drink online via a webpage. More info here!
