The intelligent cocktail machine 'Lazybar' by Jonas Autenrieth (19) and Nikolai Braun ((17)) mixes different cocktails quickly and precisely at the touch of a button. Via an LCD display and menu structure, the user can choose from a constantly updated range of drinks, which are mixed from up to ten possible ingredients. The young researchers researched bars and designed a user-friendly housing. They selected the appropriate components - including special dosing pumps and turbulence technology -, designed circuit diagrams and circuit boards and programmed the automatic processes: from the detection of glass sizes and fill levels to a constant mixing ratio and 150 recipes to the maintenance procedure and billing system.
