INTRODUCTION
a) Order Taking: Waiter robots can take customer orders using touchscreens, voice
recognition, or other interactive interfaces. Customers can input their selections, and
the robot transmits the order to the kitchen staff.
b) Food and Drink Delivery: Once the orders are prepared, the robot navigates through
the restaurant to deliver dishes and beverages to the designated tables. This reduces
the need for human waiters to carry out this repetitive task.
c) Tray and Utensil Handling: Some waiter robots are equipped with trays or
compartments to carry multiple dishes at once. They can also manage utensils,
napkins, and other dining essentials.
d) Navigation and Obstacle Avoidance: Waiter robots are designed to move
autonomously through the restaurant, avoiding obstacles and navigating around
tables and chairs. This is achieved through the use of sensors, cameras, and mapping
technologies.
e) Customer Interaction: Many waiter robots are programmed to interact with
customers in a friendly manner. This may include greetings, thanking customers,
and providing information about the menu or specials.
f) Payment Processing: Some advanced waiter robots can facilitate the payment
process. Customers may be able to make payments directly through the robot,
reducing the need for a separate interaction with a cashier.
g) Entertainment and Promotions: Waiter robots may be equipped with features to
entertain customers, such as displaying messages, playing music, or showcasing
promotions and specials.
h) Sanitization: In response to health and safety concerns, some waiter robots are
equipped with sanitization features, such as UV-C light for disinfecting surfaces or
hand sanitizer dispensers.
i) Table Cleaning Assistance: After customers finish their meals, waiter robots can
assist in clearing tables by transporting used dishes to designated areas for cleaning.
j) Customizable Features: Depending on the restaurant's needs, waiter robots may have
customizable features, such as the ability to display the restaurant's logo, convey
personalized messages, or adapt to different themes.
Implementing waiter robots in a restaurant setting can enhance efficiency, reduce
labour costs, and provide a unique and futuristic experience for customers. However,
successful integration requires careful consideration of the specific needs of the
establishment and effective human-robot collaboration.

LITERATURE REVIEW
Haixia Zeng et al., [1] Proposed design of an efficient and intelligent food delivery
robot, which can receive background instructions, choose the route, deliver the food,
and automatically returns back to the start. Used a radio frequency module to locate the
target, an infrared module to navigate, an ultrasonic sensor for obstacle avoiding, a WI-
FI module for serial communication, and MSP430 was used as a control unit.
Shruti et al., [2] is designed in such a way that it takes orders as well as serves food at
minimal human assistance. RPA is used by the system to perform tasks instinctively.
Customer has to press a button on each table to summon the servexa robot. Ultrasonic
sensors help in detecting obstacles if present in the robot's path, an OLED screen is used
to display the menu and the customer is provided with a remote to input their order
easily.
Anjali et al., [3] presents an Autonomous Robot for delivering the orders in restaurants.
The whole system is controlled by Raspberry Pi. Number of switches connected as
inputs equals table numbers in restaurants. The robot is given a predefined path using
unique identification of the table. In case of an obstacle encounter, an ultrasonic sensor
is used. Raspberry Pi processes the input from switches and ultrasonic sensors and sends
the data to motor drivers connected to two DC motors and one stepper motor.
Zeashan H. Khan et al., [4] proposes the design and development of a waiter robot
which is considered as a possible solution to restaurant automation. The desired order is
transmitted on wireless network to the kitchen via menu bar. The menu bar is based on
the LCD, Keypad and the Bluetooth module. It works on the concept of line following
using four IR sensors, where two sensors are used for line following and the remaining
two are placed at the side for the count of tables. The customer places the order using an
electronic menu bar. This order is sent to the kitchen and reception using a
communication network. Bluetooth module (HC-06) is used with a baud rate of 9600
bps. The waiter robot then transfers the food from the kitchen to the customer.
Heena Sheikh et al., [5] Today, technology is being used to make improvements in
every domain. Due to rapid development of technology, in the field of work the robots
have replaced human labor and solved many related problems. Young people choose to
enjoy a variety of food outside which led to emergence of new ideas in the food service
industry. Nowadays the demand for intelligent food delivery systems is increasing at a
rapid rate. This idea is leading towards the improvement of the cost and efficiency of
the food delivery system. This project aims at designing a low cost, efficient
autonomous robot with a smart ordering system.

COMPONENTS
5.1 Arduino Mega
The Arduino Mega is a microcontroller board based on the ATmega2560 as shown
in the Fig. 5.1. It is an enhanced version of the original Arduino board, offering more I/O
pins, memory, and features. Here are some key aspects of the Arduino Mega.
Power Supply: The board can be powered via USB connection or an external power
supply. It operates in the voltage range of 7-12V.
Reset Button: A reset button allows you to restart the microcontroller, restarting your
program.
Compatibility: The Arduino Mega is compatible with the Arduino IDE (Integrated
Development Environment) and can be programmed using the Arduino programming
language.
Shield Compatibility: The Mega is compatible with most Arduino shields, which are
additional boards that can be plugged into the Arduino to extend its capabilities. The
Arduino Mega is particularly useful for projects that require a large number of digital
and analogy I/O pins or demand more program memory and RAM than the standard
Arduino boards can provide. It is commonly used in robotics, 3D printers, and other
projects where expanded capabilities are necessary. Its versatility and compatibility
with a wide range of sensors, actuators, and shields make it a popular choice among
makers and hobbyists
Motor Driver: A motor driver is an electronic device or circuit that controls the motion
and direction of a motor. It acts as an interface between the microcontroller or other
control circuit and the motor. Motor drivers are particularly essential for DC motors,
which require a specific type of control to manage their speed and direction. Motor
drivers typically handle tasks such as amplifying the control signals, providing
sufficient power to the motor, and managing the current flow to prevent damage.

5.4 Battery
A battery is a source of electric power consisting of one or more electrochemical
cells with external connections for powering electrical devices as shown in Figure5.4.
When a battery is supplying power, its positive terminal is the cathode and its negative
terminal is the anode. The terminal marked negative is the source of electrons that will
flow through an external electric circuit to the positive terminal. When a battery is
connected to an external electric load, a redox reaction converts high-energy reactants to
lower-energy products, and the free-energy difference is delivered to the external circuit

5.5 Shaft
In mechanical engineering, a shaft shown in Fig. 5.5 is a rotating machine
element, usually circular in cross section, which is used to transmit power from one part
to another, or from a machine which produces power to a machine which absorbs power.
The material used for ordinary shafts is mild steel. When high strength is required, an
alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts
are generally formed by hot rolling and finished to size by cold drawing or turning and
grinding.
It should be known that all gravity loads in skeleton frame structure are supported
by beams and columns. The distance between columns can be established according to
the functions and requirements of the structure. Therefore, there are no restrictions that
limit the area of the floor and roof of the building. Multi store structures are possible to
construct using skeleton framing. The Fig. 5.6 shows the supporting frame.
