INTRODUCTION
This project is related to a voice controlled car, which makes this project an important part of identifying commands and delivering them to the car via a wireless system. We have designed a Car that is using sensor to interface controller and android, and has various purposes.
The android operated vehicle is a concept where a human being can control a vehicle by an android app by remote or wireless operation, with or without physically being seated inside it. The project comprises of a vehicle powered the control of several motors, sensors and relay using microcontroller that will be connected to the motors and other parts of vehicle.
PROBLEM STATEMENT
The prime objective of this project is to control a real world car remotely by using voice commands
Challenges:
Main challenges for this project includes:
- Availability of Car
- Software Malfunction
- Tackling with voice command failure
- Connection with kill switch as evacuation plan
- Appropriate Components Selection
Scope And Need of the Project:
Scope of the project is to develop a system which will be able to work over a voice command and perform desired action. The prime objective is to control a real world car remotely by using voice commands. People who historically have difficulties with driving, such as disabled people and older citizens as well as very young, would be able to experience the freedom of car travel.The main intention behind this project is to help impaired persons. We tried to develop a Voice control smart car .We dreamed, a simple Car that is controlled wirelessly by android application for various purposes. This low-cost project would help the impaired people successfully,which could help them protecting themselves and surroundings from some severe dangers.

Project ObjectivesPROJECT OBJECTIVES:
AIMS & OBJECTIVES:
- To research and study about such equipment (motors, drivers and actuators) which can move an object (vehicle).
- To select the best hardware which is fast, efficient and accurate for the system in real-time
- To develop such a system, this can automate the process of driving via voice control.
- To study about sensor module, in order to receive a voice that can be used for object (vehicle) control.
- To assemble such a device which can hold motors and actuators at specific place and act accordingly.
- To train our model, classification of commands which means the model has to identify if the voice is commanding forward, backward or any other command specified.
IMPLEMENTATION METHOD:
METHODOLOGY
We proposed to build a Voice Control Smart Vehicle. It works on the basis of voice recognition using Android app. The main purpose of this project is to come up with an ease way of driving for impaired people. The block diagram of the whole process is shown in the following Figure.

This project can be used for research purposes by University and Students.
- Ease of use for disable
Voice control allows the driver to operate a car’s function through speaking instructions instead of using physical buttons
- Driving comfort
This project provides driving comfort, specially for the impaired persons
Technical Details of Final DeliverableTECHNICAL DETAILS:
MODULE :01
- CIRCUIT FOR PROJECT PARAMETER OF CONTROLLING GEAR :
The hardware for gear contains a structure where two Dc motors are used. The purpose of motor M1 is to control the x-axis (left and right) movement of the gear lever and of M2 is to control the y-axis (upward and downward) movement of the gear. An H-Bridge motor diver (L293D) is used to drive the motors. At this stage IR sensor is used to create communication path between Android and Car. Arduino Uno R3 is used as a microcontroller and a cathode 7 segment display to the commands given to the controller.
GEAR MECHANISM:
Initially the gear is at the neutral position and we can give command to the system through the remote.When 1 button is pressed to apply the first gear the motor M1 shift the gear lever to the left direction and as it reaches the maximum position it will turn off and motor M2 will shift the lever in the upward direction and 7 segment will show the 1 appeared on it which shows that first gear has been applied successfully. The mechanism followed here is A COREXY mechanism. The same process will be applied for the second , third and the gears uptill reverse gear. ( shown in fig 2)For Second gear 2 button is pressed , motor M1 is shifted to left direction and motor M2 in the downward direction For Third and Fourth gear there is no need of motor M1 , motor M2 will shift the lever in upward direction to apply the Third gear and in downwards direction to apply the Fourth gear.To apply the Fifth gear the motor M1 will shift the gear lever to the right direction and as it reaches the maximum position it will turn off and motor M2 will shift the lever in the upward direction and 7 segment will show the 5 appeared indicating that fifth gear has been applied .For the reverse gear , motor M1 is shifted to right direction and motor M2 in the downward
MODULE :02
PADDLE SYNCHRONIZATION
- PADDLE CONTROLLED MECHANISM
In manual car we have three paddles ; Race , Brake and Clutch.The similar mechanism as gear ,the CORE-XY is implemented here.To control Paddles only one axis is used ,as when ever the paddle is pressed it decompresses on its own based upon the principle which is already builtin in the car called spring Mechanism.The purpose of DC Motor here is to press the paddle and it decompresses on its own .So whenever gear is applied the paddle ( clutch) will reach the maximum position i.e fully pressed. To count the rotations encoders are used .To achieve the biting point , the point where we shall apply the race .So whenever clutch reaches the biting point , the paddle (Race) slowly starts reaching its position according to the requirement of the speed and the clutch decompresses slowly via the micro-controller and all is based upon encoders to count the rotations and thus the speed is controlled via it .When ever the brake is applied the clutch shall fully reach its maximum position .
