This document summarizes a technical seminar presentation about developing a voice-controlled smart robotic assistant. The robotic assistant operates on human voice commands given through an Android device using speech recognition and transmits commands to the robot over Bluetooth. The robot is built using an Arduino microcontroller and can complete various tasks like moving forwards/backwards, rotating, and opening/closing its hands through the voice commands. The presentation covers the system block diagram, components used, and concludes the robotic assistant is feasible and could be applied in industries, rescue operations, or for assisting disabled people through further development.

4. ABSTRACT
Smart robotic assistants help human beings in reducing the
manual efforts in day-to-day tasks and the risk to precious
human lives in hazardous situations.
In this we develop a smart robotic assistant that operates on
human voice commands, given remotely by using an Android
platform based smart IoT device.
The real-time signal processing of the voice commands is
carried out using a cloud server.
The speech command signal converted to text form is then
communicated to the robotic assistant over a Bluetooth
network.
The robotic assistant is developed on an Arduino micro-
controller based platform.

5. INTRODUCTION
Human life is valuable and human efforts at premium.
People can get injured while handling hazardous
chemicals or explosives, in chemical industry or in
explosives manufacturing industry, respectively.
Inside homes, people may need assistance to reduce
manual effort, needed critically in case of physically
challenged people.
Assistant robots can be used in manufacturing sector
for different tooling and re-positioning operations.
In this we develop a voice controlled smart assistant
robot that can perform different operations for
applications in homes, hospitals and industries.

7. How RoboticAssistant Works
The movements of the smart RA are controlled by
speech commands given through a smart mobile
phone using Android OS based platform.
The voice commands signal is converted to the text
form, using an online cloud server in real-time.
Using a smart IoT device, this text command is then
transmitted to the Bluetooth module on-board the
robot.
The Bluetooth module receives the signal and then
sends commands to the micro-controller, on-board the
RA’s body.

8. The micro-controller in turn processes the commands
and controls all the 4 DC motors used for various
movements.
In the receiver side, the micro-controller ports are used
as interface between the Bluetooth receiver and the RA.
The movements of the RA’s body, hands and arm are
independent of each other and all can be controlled at the
same time, since each function is controlled by motors.

12. Arduino is an open-source computer hardware and software
company, project and user community .
It designs and manufactures microcontroller-based kits for
building digital devices and interactive objects that can sense and
control objects in the physical world.
These systems provide sets of digital and analog I/O pins that can
be interfaced to various expansion boards and other circuits.
 The boards feature serial communication interfaces,
including USB on some models
What Is Arduino Microcontroller

13. CONCLUSION
It is feasible to implement Bluetooth communication
between smart phone and microcontroller.
The development of apps for Android in Android
SDK is easy and free of cost.
This topic should be helpful in showcasing an IoT
application in developing a voice-controlled smart
robotic assistant.
Areas that can be explored further are, the effect of
the distance between the mouth and the smart IoT
device on the performance of the robot, and the effect
of noise on the speech to text conversion.

14. APPLICATIONS AND FUTURE
ENHANCEMENT
1. It can be used in various industries for picking
various objects where human intervention is not
desired.
2. On a large scale, it can be used to develop robots
with military applications. It can be used to target
enemy without any human being crossing the
territory.
3.It provides for more development of applications
based on android operating system. Such as ,
Application based on sensors.

15. This opens door for wide range of possible
similar applications
i. Remote starter for car
ii.Automation of household tasks
4. It is robust, sensitive and fast moving, hence
can be applied in rescue operations.
5. With tremendous smart phone in markets, it is
bound to have many more applications in near
future.
