Abstract
In this project, a voice-controlled personal assistant Robot has been designed. The
robot is capable of taking the human voice commands from the mobile app. It can take
the instructions and run them. It also provides a message using the sound signal. The
project is designed using a micro- controller related system. The performance can be
evaluated by obtaining good results of the starting experiments. Some better practices
are also studied involving some uses in the houses, medical treatment, cars and
industrial areas.
In the system discussed here, a speech recognition system is not needed for the
recognition of the human voice for controlling the robot. In the system used, an android
application has been used for the recognition as well as the processing of a person’s
sound that can be next converted to textual format ( using the speech to text converter
for this purpose ). The textual data can be moved towards the robot by the use of a
Bluetooth device. The textual data can be further altered and studied using the
microcontroller for controlling the robot accordingly. The purpose of this task is the
development of a simple robot hardware architecture having strong computing devices
so that the designer of the robots can pay attention on the research and studies and not
on the Bluetooth connection study. The students can also very effectively use the system
to carry out various experiments for the study of small applications of the system. It is
not very costly and very easy for using also.

Introduction
Background
The project is to design a system with a robot that is capable of receiving the
commands using Bluetooth and working as per the instructions and also to design an
android application that allows a user to send the commands by using Bluetooth. The
robot is to be fitted with an Arduino UNO which is a microcontroller which on
receiving the command received via the Bluetooth and controls the driver motor. At first
stage the skeleton of the project was designed which was based on my research and
many related videos. After finalising the design the basic structure of my project was
designed. An andriod phone is to be used to input the command. The Bluetooth system
has to be used for receiving the command from the Android phone and for transmitting
the command towards the micro controller, which inturn drives the driver motor. After
studying about the circuits and based on my requirements of the working methodolody
of the robot the following block diagram was finalised.
Aims & Objectives
Controlling a moving object by voice is gaining more and more application. A super
market trolly controlled by voice is a popular example. This eliminates the need for the
buyer from pushing the trolly along with them. The buyer can just command the trolley
to follow them by voice control. In this project, we tried to control the movement of a
supermarket trolley with voice.
Project Specification
The trolley is fitted with wheels and DC motor driver. The blue tooth module fitted to
the trolley receives the voice from the buyer and feeds to the Aurdino micro controller.
The trolley is made to receive signals from the buyer for forward, reverse, left and right
movement. The driver of the motor is connected to the Ardunio controller. The DC
motors ( 2 ) are being employed for moving the trolley in various directions like the
5

forward, reverse, left or right direction. A 9V battery can be employed for powering the
motor driver in order to drive the motors.
The chosen task is the design of a system using a robot which can be controlled using
both voice signal and smart phone APP. In this project, a robot is built which is capable
of receiving a command using bluetooth and working as per the coommands. The
android application is developed that lets the user send the commands using a bluetooth
device. The Commands are interpreteded using a bluetooth modem which is attached to
Arduino UNO. The Arduino can control the motor that allows the movements of the
robot.
An example of a voice controlled robot is depicted in figure 1.
