General Description: We plan to make an automated drink mixer system that mixers based on pre-loaded recipes. This device would have preselected drink supplies that uses a pump to make various drinks. This automation will solve long lines at bars. Solution: The user would scan a RFID card on a RFID sensor to provide identity, then use a controller to navigate through the mixed drinks on LCD screen and select one. The recipes will be pre-loaded onto microcontroller memory as a file. Through this user interface, our microcontroller will store who ordered which drink and keep a tab. A solo cup would be positioned on a rotating disc (using a step motor) below pouring nozzles evenly spaced out in a circular formation. Peristaltic pumps would pour out the right amount into the cup as required by the recipe. When different liquids need to be poured, the disk will rotate and position the cup below the needed liquid. The positioning will be precise through using a stepper motor, preventing movement of the disc beyond desired angular movement. The pouring will be done with high precision through using flow gauge sensors. Additional features include a warning system to identify which ingredients are getting low (using weight sensors and LEDs), sensors to verify that there is a cup in place to avoid spills, and wifi/bluetooth enabled. While using water may be a concern with electronics, our implementation does not use high pressure (minimizing potential sprays) and can be tested/demoed keeping water components a safe distance away. The machine shop confirmed our mechanical structure is easy to build.
