Abstract – The project outlines the design and development of a Serving cum Waiter Robot which is considered as a possible solution to address the lack of human resource and to introduce Automation.The Human waiters are replaced by the Robots as Servers and Waiters In cafes, restaurants and Hotels. The lack of human resource can be addressed by automation through an electronically automated system called Serving Robot which does the job of a Waiter, Server as well for ordering food items and beverages. The menu bar comprises of a OLED display screen,4*4 Keypad and a WIFI module. The Patrons can place an order with the help of 4*4 remote/keypad built on the robots body. The robot receives the order request from the patrons and the same is forwarded to the kitchen.
Keywords – RPA, Node MCU, OLED, Keypad.
As the world is emerging towards new trends and technologies, there is a need to invent something that is more attractive and useful for the citizens. In the present approach we are introducing Automation into picture which makes things much simple. Basically, Robotic Process Automation is a technology that uses robots to automate monotonous tasks and manual processes. The entities which emulates certain actions are called Robots. Automation is any process which is done by minimal human assistance.
All the actions take place in a virtual reality and not on screen; the robot does not need a screen to operate, rather it elicidates the screen display electronically. The intelligent circuitry along with the potentiometer makes the servo to rotate accordingly. The buttons are placed on each table to summon the Robot which makes the job very easy. Each switch is of 3volt in this way a very small amount of energy is consumed. The ultrasonic sensors are placed inside the robot in order to detect the obstacles lying in its path. OLED screen is used to display the contents of the menu. A 4*4 Remote/keypad is provided for user inputs, So that the customers can order easily by themselves using the keypad on the Robots body.
LITERATURE SURVEY Serving Robot New Generation Electronic Waiter: In todays modern world the use of robot is rapidly increasing. Robots are capable of doing work more effectively and efficiently than humans. One such example can be SERVING ROBOT. There are multiple researches done on serving robot. The paper shows the working of Serving Robot which will take order as well as serve the food to the customer. The implementation is done with available resources to reduce the cost of project.  Smart Floor
Cleaning Robot: With the advancement of technology, everyone wants their tasks to be done in a easiest possible approach. The paper concentrates in designing of a Smart Floor Cleaning Robot. The robot can work in both manual and autonomous modes including scheduling for specific time and bag-less dirt container Waiter Robot Solution to Restaurant Automation: The main idea of this paper is to design a robot or an agent that can do the job a Waiter. The problems regarding Increased waiting time can be handled with the help of this Waiter Robots. The wished order is forwarded to the kitchen.  Social Service Robots in Public and Private Environments: Research on service robots majorly in hospital industries has been increased nowadays due to this covid-19 pandemic. Possible solutions are to be addressed to overcome the problems faced by the health care professionals in the treatment of their patients without being infected themselves in treating the patients.
The proposed system contains both hardware and software tools as components. Here the Raspberry pi is used to establish the connection with the software and hardware components. It also contains Node MCU device which will be used to establish the connection between the Robot and the tables. So that the robot will exactly know to reach the respective table which is requesting for the service. Raspberry pi and Node MCU communicates through http request and response procedure with help of Wi-Fi.
Node MCU: Node MCU is less expensive open source IOT platform. Node MCU is used to establish the connection with the tables. It uses Wi-Fi modules for connection. In the project the robots will be trained to serve food as well as to do the Waiter job.

RESULTS AND DISCUSSION
The system uses RPA, is a process that is used instinctively perform certain tasks or operation. Normally all of these actions take place in avirtual reality and not on screen. So, in order to request the Servexa robot the customer should press a button present on each table which makes the task of requesting the robot easier. Each button on the table comprises of 3v of power output and hence the amount of energy consumed is very less. As soon as the button is pressed the robot moves towards the table. Whenever the robot encounters an obstacle in its path, the IR sensor present on the robot will detect the obstacle by observing the change in output of sensor it sends a signal to the buzzer and the beep indicates the presence of obstacles in the path. The customers order
via keypad that is placed on the robot. Customers view the menu, price and make order directly using this system. Then the order will be displayed on the OLED display even that is present on the robot. Autarchic(autonomous) serving robot collects the order as well serves the food to the respective tables assigned.

This project helps in reducing the lack of human resources to serve in restaurants. The Robot is cost effective once we built later just maintenance is required. In the future work the innovation of the hardware and software components will be done. This model can be used in the hospital to serve a food and medicines for the patients, and in the apartment or in some gated communities to deliver a food or food items. To be more clear and precise the present project is not for a specific use rather it has multiple uses as well. So,with the help of RPA it is easy to achieve time efficiency, cost reduction, efficiency in work and also it addresses the requirement of man power.
