CHAPTER I
1.1 Abstract
The objective of this project is to enable users to remotely control their home appliances and systems using a cell phone-based interface. To access the control unit, the user should send an authentication code along with the required/desired function/action to his/her home control system via GSM. Upon being properly authenticated, the cell phone-based interface at home (control unit) would relay the commands to a microcontroller that would perform the required function/action.

Abstract
In this project, we present controlling of a Robot using DTMF technique.
The robot is controlled by a mobile phone that makes call to the other
mobile phone attached to the robot. In the course of the call, if any button
is pressed, tone corresponding to the button pressed is heard at the other
end of the call. This tone is called dual tone multi frequency tone (DTMF).
Using DTMF code, direction of motion of the robot can be controlled by
mobile phone. Robot has a RF camera that transmits an actual video at the
operator ....etc
