VOICE-ACTIVATED ROBOTIC VEHICLE: A HANDS-FREE CONTROL SOLUTION

Abstract

This project work is designed to control a robotic 
vehicle through voice commands forwarded through 
smart phone using android application. The wireless 
communication link established between the android 
app and the vehicle is facilitated with Bluetooth 
technology. The main motive to build this voice 
controlled robotic vehicle is to analyze the human 
voice and act according to the predefined programmed 
commands. The most basic commands included here 
are forward, backward, right turn, left turn and stop. 
The vehicle will be controlled wirelessly with the use 
of android smart phone technology and it is very 
simple also economy point of view, it is very feasible 
or affordable. 
The main processing unit will be constructed using 
Arduino Uno development board and with the help of a 
Bluetooth device interfaced with this processor, 
received commands will be digitalized. The moving 
mechanism will be constructed using 2 DC motors and 
these 2 motors are driven independently through motor 
driving circuit designed with H Bridge IC. The 
commands delivered from the android application 
through phone Microphone are converted in to digital 
signals by the Bluetooth RF transmitter & the range is 
defined as 50feets approximately.
