The MixRMastR, a creation of Cybot Galactica, represented a line of droids. Dominating the bartender droid market, it was closely followed by the C5 model from LeisureMech Enterprises. Exhibiting a vaguely humanoid form, the MixRMastR was a frequent fixture in taverns situated in or around bustling starports, where efficiency outweighed the importance of cultivating repeat clientele.

Standing at just under one meter tall, this droid was designed for secure attachment to a table or counter. Equipped with a basic vocabulator and audio sensors, it could engage in simple interactions with patrons. The MixRMastR received its supply of soda water and various alcohols through a network of tubes connecting it to the storage area. Its rapid processor analyzed drink orders, matched them against its extensive database of beverages, and dispensed the required ingredients into a glass. The completed drinks, along with payment collection, were handled via a retractable tray at a pace considerably faster than a biological, or organic, bartender could achieve.
Furthermore, Cybot Galactica engineered a version incorporating a repulsorlift, granting it the ability to move around the premises and serve beverages. This particular model was conceived as a cost-effective solution for establishments unable to afford installing a dedicated droid at each individual table.
An additional advantage of deploying these mechanical servers was their capacity to cross-reference a customer's order with their species' unique bio-chemistry, thereby preventing accidental self-poisoning.
