Detailed Design Report: Robotic Waiter System and Functionality

This report details the design of a robotic waiter, named Doraemon, exploring its functionality, physical design, and ethical considerations. The report includes secondary research on robotics, focusing on the robot's ability to perform human-like functions using advanced technology and software. It outlines the robot's expected capabilities, such as navigating paths, sensing customers, and serving with good gestures. The main body covers the robot's functionality, including MCU connections, navigation, customer interaction, and IT systems. It also presents a block diagram of the robot's framework, physical design with driver wheels and load trays, and discussions on ethics and safety, including power systems, speed regulation, and safety features like accessibility and wireless technology. The report concludes with an evaluation of the design, highlighting its strengths and potential areas for improvement, such as increased AI involvement and enhanced safety measures. References include books and journals related to robotic waiter design and implementation.

INTRODUCTION
This report is all about designing the robotic waiters through advanced technology and
software. The following discussions is based on designing the waiter which is actually a machine
but can perform human functions, it mainly consist the researches, diagrams, flowcharts,
security, privacy and requirements in designing the robot waiter. The robot which is taken in this
report is named as Doraemon because it is name of one of the cartoon series which describes the
robotic cat who can do anything by it's gadgets and serve people in helping them. Similarly,
Doraemon waiter's functions will be like this only, he will serve the customers at it's best with
full satisfaction with the help of it's software installed and functions assigned to it. Expected
results of a report is to design a waiter by specific technical configuration and maintenance with
cost-effective process (Development of a Robotic Waiter System, 2020).
MAIN BODY
Secondary Research:
Robot is a machine that is computed programmable, they are capable of doing functions
like human does automatically. It's software defines that either the robot is guided by external
sources or instructions are embedded within them only. Working of robot is, it consist movable
feature, motors, sensors, power supply and brain like a computer, all these elements controls a
robot. They have both kinds of behaviour, human as well as animal. There are challenges faced
to in designing and maintenance of robot such as efficiency in power resources, manufacturing,
mapping of an environment, privacy and ethics, reliability in artificial intelligence and multi-
functionality (Csorvási, Nagy and Vajk, 2017).
Functionality:
 Connection between robot's MCU (Multipoint control unit) and kitchen's MCU need to
be generated to send information.
 Robot must navigate the path on it's own.
 Robot must sense the customer who is entering the door or ordering something.
 It should have a smiling face and greetings to the customers.
 It must track customers about their activities.
 It should have an ability to serve with a good gesture and security.
 It must have an advance IT systems and ethics to work in the restaurant.

Block diagram of functions:
The framework of robotic waiter needs four parts. The robot itself will navigate from one
location to another location through it's senses and motors attached in it. It has that capability to
calculate the footsteps and path to move on. It consist the power distribution channel of 27 V
which assist the robot to generate the power itself. Current of the motor will be 1.6-1.8 A.
Kitchen also consist it's own central control unit, all the instructions are given through kitchen
will be attended by the robot and pass information accordingly (Hamdany, Albak and Al-Nima,
2019). It's own power distribution is 3 V.

Physical design:
This is the physical view of the robot. It is supported by driver wheels which are two in number,
and these are connected to motors. There are six wheels which will support the weight and
stability of the robot. Motors will also calculate the distance that the robot will travel. Base of the
robot consist of MCU, Bluetooth, transmitter and receiver. Load tray is used to carry the food in
the restaurants (Kamruzzaman and Tareq, 2017).
Ethics and Safety:
Safety concerns which are associated with it are power system in the robot which needs regular
maintenance. To avoid ill fated incidents, alkaline batteries are used for safety purpose in power
circuit. According to IEEE code of conduct, it is important to ensure that movement of robots
must not be harmful for the human around it. To sort this problem out, walking speed of the
robot is regulated in it's systems. And if it occurs then there are the usage of circuit breakers in
3

the systems to avoid such problems. Moreover, it consists safety features like it's accessible,
visually impaired, colour blindness, language options, hearing power, facial recognition and
safest wireless technology (Mishraa, Goyal and Sharma, 2018).
Evaluation:
A robot is designed named Doraemon, there are four modules created to build a robot,
keeping in mind the safety measures and accessible system. Diagram, features and designing
went well in the whole report. Next time many things can be done differently like more
involvement of artificial intelligence, automated system, more safety and ethics.
CONCLUSION
It is concluded that robotics is designed by combining two fields: Software and
mechanical engineering. Internal systems are all coordinated by software like voice, hearing and
brain. External systems are all operated through study of mechanics like activities, motors,
wheels and many more. Moreover, ethics and safety is also discussed in this report with full
evaluation.
