Abstract [en]

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.

Abstract [sv]

Syftet med denna rapport var att utvärdera genomförbarheten av en autonom dryckesautomat där den kunde komplettera servitören i sina många uppgifter. Prototypen kan med hög noggrannhet hälla upp en stor variation av drycker utan behovet av en mänsklig operatör.

 Projektets fokus var att kunna hälla ett stort antal drycker med så hög precision som möjligt. Genom automatisering kan detta uppnås utan behov av utbildad personal.

Många olika slags komponenter krävdes för att göra prototypen så konsekvent och säker som möjligt. Det visade sig att denna variation skapade problem och hade en negativ effekt på det önskade slutresultatet.

Den slutliga prototypen kan hälla upp vätskor från sex olika källor. Många tester gjordes med en maximal avvikelse från den förväntade volymen på 7.7%. Detta var en stor förbättring på standardavvikelsen i alkoholhaltiga drycker, vilket är 42%. Prototypen kan hälla upp till 116 drycker per timme.
