Final
For my final project I wanted to create a drink dispensing machine. While doing research to see what has been done before I did find a lot of designs that varied in construction and how it worked. There is also some commercial products for bars and home use but have extremely high cost. For this design project the most important part of the system is the when to dispense the liquid. My ideal project is to create a drink dispensing system that is expandable and have the ability to have a menu based on what types of liquids are in the system. After a lot of research for the pump I choose to use a peristaltic pump to dispense the liquid because the liquid does not touch any of the moving parts and can keep items sterile.
