TELE REMOTE ROBOTIC CAR
[attachment=20224]
INTRODUCTION
A remote control vehicle is defined as any mobile device that is controlled by a means that does not restrict its motion.
This is often a wireless control device.
It is just like robot in the sense that it can be controlled by a human and does not takes positive action autonomously.
COMPONENTS REQUIRED:
Chassis.
Two Mobile phones.
Batteries.
Motors.
Wheels.
Hands free.
Robotic kit.
DTMF TONE
DTMF tone is the signal to the network centre that is generated when we press any key of our mobile phone.
In DTMF, each key we press on the phone generates two tones of specific frequency.
So a voice can’t imitate the tones.
One tone is generated from a high frequency group of tones and another from a low frequency group.
DTMF DECODER
Motorola MT8870 is widely used in electronic communications circuits.
18-pin IC.
Used in telephones and a variety of other applications.
MT8870 is integrated with DTMF decoder.
It detects and decodes all the DTMF tone pair into 4 bit binary code.
APPLICATION
Using the tele remote one can remotely control switching of two DC motor
Just by dialing a key from remote mobile phone at calling side we can perform all the movement operation of a robotic car via another mobile phone.
The ranges of CAR that to be controlled depend upon the person's usage. Forward, Reverse, Right, Left switching can be controlled once they are connected to kit.
ADVANTAGES
The main advantage of this remote control CAR is its unlimited range, as connection is established using mobile phones.
Due to presence of obstacle detector positioning and adjustments are not required at all.
Thus working is easy and only CAR motor connection to kit and kit's connection to mobile phone is to be done and serves just like plug 'n' play.
