A.D.D : Autonomous Drink Dispenser

Abstract: The purpose of this report was to evaluate the feasibility of an autonomous drink dispenser where it can complement the waitstaff in their many duties. The prototype can accurately dispense a wide variety of drinks without the intervention of a human operator. The focus of the project was to pour a wide variety of drinks as accurately as possible. This can be achieved without the need for trained staff through automation. Many different components were required in order to make the prototype as consistent and safe as possible. It was discovered that so many components negatively affected the end result. The final prototype can dispense liquids from six different sources. Numerous different tests were done with the maximum deviation from the expected volume being 7.7%. This was a vast improvement on the standard deviation in alcohol content in drinks, which is 42%. The prototype can dispense up to 116 drinks per hour.
