Now-a-days, automated machines can be found everywhere in our everyday life. For example, automated machine can be found at the train stations selling train tickets. In the schools and offices automated machine provides drinks and snacks which is providing facilities to human being. And sales of goods and services via automated machine are growing strongly in India provides easiest lifestyle. Automated machine modeling is the crucial part in developing proposed model as this reduces the human resources and has been modeled using. This dissertation describes a model of an automated machine totally based on Mealy concept of FSM. The proposed model will increase the efficiency of automated machine and will also lead to cost reduction, saving time and ease of usage. The first phase involves selection of items to be purchased by consumer. In next phase, the machine generates the respective total amount required to be paid. At last the vendee enters the amount to get their products dispensed and the extra amount will be returned back by machine. Keywords Automated machine, FSM, Mealy, Product dispensed, and Vendee. 1. INTRODUCTION The first commercial coin operated machine was introduced in London and England used for selling post cards [11]. Sometimes automated Machines are used to dispense various products when money is inserted into it, in the absence of salesperson. The automated machines are more accessible and practical than the convention purchasing method. In banks as ATM machine is the best example of automated machine. 1.1 Operation of Vending Machine [10]  When user presses the button the machine will tell the user that the product is available or not, for that it will display a message  When users select the product and quantity of product, it will automatically calculate the net amount required to be paid/insert.  User will have to now insert the specified amount for purchasing the product. Then machine will verify the amount provided.  If extra amount is provided then it will check for change to return. If it available then it will return the change and will dispense the product. Otherwise it will cancel the product and return the amount inserted.
