Conventionally, Wireless-controlled robots use rf circuits, which have the drawbacks of limited working range, limited frequency range and the limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantage of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controlles.
Although the appearance and the capabilities of robots vary vastly, all robots share the feature of a mechanical, movable structure under some form of control. The Control of robot involves three distinct phases: perception, processing and action. Generally, the preceptors are sensors mounted on the robot , processing is done by the on-board microcontroller or processor, and the task is perfomed using motors or with some other actuators.
i want to make it clear, if you face any problem i am dere for you

Signing UpStep 1: PROJECT OVERVIEW
In this project the robot, is controlled by a mobile phone that makes call to the mobile phone attached to the robot in the course of the call, if any button is pressed control corresponding to the button pressed is heard at the other end of the call. This tone is called dual tone multi frequency tome (DTMF) robot receives this DTMF tone with the help of 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 in to its equivalent binary digit and this binary number is send to the microcontroller, the microcontroller is preprogrammed to take a decision for any give input and outputs its decision to motor drivers in order to drive the motors 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 this simple robotic project does not require the construction ofreceiver and transmitter units.
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 dialing is known as touch tone .
DTMF assigns a specific frequency (consisting of two separate tones) to each key s that it can easily be identified by the electronic circuit. The signal generated by the DTMF encoder is the direct al-gebric submission, in real time of the amplitudes of two sine(cosine) waves of different frequencies, i.e. ,pressing 5 will send a tone made by adding 1336hz and 770hz to the other end of the mobile. The tones and assignments in a dtmf system shown below

im very interested in GMS or DTMF projects
i want to learn it
could u please mail me a soft copy of your project along with circuits and datasheet ?
thankyou so much in advance and im waiting for your reply
i am working on this same project......
i use ATMEGA16 controller ic.
my problem is that the controller's port-D is connected to motor driver ic-L293D. But i don't get the output from port-D thus i don't give the output signal to both DC motors. So what is problem in my circuit??????
please give me some answer as possible........
note: mobile should be on self answering mode

Need ur reply.. thnx
Could u provide the full circuit description this circuit so i can work on it.My email id is surved18sep@yahoo.co.in .
i have an IC of ATMEGA32
can i use your hex code of atmega16 to burn into atmega32????
shoud it work properly???
or would we have to change something in hex program
plz...... tell me sir???
