EYE ON A CELLPHONE-OPERATED LAND ROVER




ABSTRACT:
Our project and implimentation name is “EYE ON A CELL-PHONE OPERATED LAND ROVER”. In this name ‘EYE’ stands for wireless camera which is placed on robot and ‘LAND ROVER’ stands for vehicle which can move along the surface.
In this project and implimentation robot is controlled by cell-phone that makes a call to the cell-phone attached to the robot. In the course of a call if any button is pressed a tone corresponding to the button pressed is heard at the other end of the call the tone is called dual-tone multiple/frequency (DTMF TONE) the robot perceives this DTMF tone with the help of the phone stacked in the robot.
The received tone is processed by the ATmega16 microcontroller with the help of DTMF decoder MT8870.The decoder decodes the DTMF tone into its equivalent binary digit and this binary number is send to the microcontroller. The microcontroller is preprogrammed to take a decision for any given input and out-puts its decision to motor drives in order to drive the motor for forward or backward motion or a turn.

The received tone is processed by the ATmega16 microcontroller with the help of DTMF decoder MT8870.The decoder decodes the DTMF tone into its equivalent binary digit and this binary number is send to the microcontroller. The microcontroller is preprogrammed to take a decision for any given input and out-puts its decision to motor drives in order to drive the motor for forward or backward motion or a turn.
The mobile that makes a call to the mobile phone stacked in the robot acts as a remote. So the simple robotic project and implimentation does not require the construction of receiver and transmitter unit.
DTMF signaling is used for telephone signaling over the line in the voice-frequency band to the call switching center. The version of DTMF used for telephone tones dialing is known as ‘touch-tone’.
DTMF assigns specific frequency to each key so that it can easily be identified by the electronic circuit. The signal generated by the DTMF encoder is a direct algebraic summation, in real time, of the amplitudes of two sine(cosine) waves of different frequencys,i.e.,pressing ‘5’ will send a tone made by adding 1336 Hz and 770 Hz to the other end of the line.

PROJECT REPORT ON

CELL PHONE OPERATED ROBOT

HISTORY OF REMOTE CONTROLLED VEHICLES:
The First Remote Control Vehicle /

Precision Guided Weapon :
This propeller-driven radio controlled boat, built by Nikola Tesla in 1898, is the original prototype of all modern-day uninhabited aerial vehicles and precision guided weapons. In fact, all remotely operated vehicles in air, land or sea. Powered by lead-acid batteries and an electric drive motor, the vessel was designed to be maneuvered alongside a target using instructions received from a wireless remote-control transmitter. Once in position, a command would be sent to detonate an explosive charge contained within the boat's forward compartment. The weapon's guidance system incorporated a secure communications link between the pilot's controller and the surface-running torpedo in an effort to assure that control could be maintained even in the presence of electronic countermeasures. To learn more about Tesla's system for secure wireless communications and his pioneering implementation of the electronic logic-gate circuit read 'Nikola Tesla — Guided Weapons & Computer Technology', Tesla Presents Series Part 3, with commentary by Leland Anderson.
