Development of an Automatic Custom-Made Drink Making System Using PLC and Java Applet

Recently, due to the increasing demand on custom-made soft drink, this paper has developed an automatic drink making system by using a networked programmable logic controller (PLC) and Java applet. In the present scheme, a Java-based and cross-platform applet is designed for users to send customized order from a smartphone (or PC) to the PLC through Internet communication. Moreover, a simplified PLC-controlled drink making mechanism is implemented to produce the custom-made drinks. Finally, several application cases are provided to demonstrate the feasibility and practicality of the developed system.
