Cell phone controlled Robot is prototype project which is controlled by a cell phone. User have to call to the mobile phone attached to the wireless robot. And while calling, user have to press the button to control the robot. The robot get the DTMF tone of pressed button and controlled the robot according to that command.

Cell Phone controlled Land Rover using 8051 micro controller is basically made to operate robots by cell phone in order to simplify the control of robots. It is mainly focused to overcome the limited working range of wireless controlled robots which uses RF circuit. Cell phone controlled robot provides the advantages of robust control and increases the working range as large as the coverage area of the service provider. There is no any interference with other controllers and give up to twelve controls. It enables you to control the your robot only by pressing of your mobile key from anywhere just like that your cell phone works as remote control. Although, the Cell phone controlled robot’s appearance and capabilities vary vastly. In spite of the fact all robots share the feature of a mechanical, movables structure under some form of control.


There is a mobile phone say MB1 that makes a call to other mobile phone say MB2 which is attached to the robot to control it. After making a call, the mobile phone MB2 automatically receives the call and wait for another instruction. Now administrator has to press the key of mobile phone MB1 according to our defined for each operation of robot. The mobile phone MB2 receives the ‘Dual Tone Multiple frequency’ (DTMF) tone by headphone and proceeds it to the circuit attach with it. Now, the received tone is processed by the micro – controller with the help of DTMF decoder IC MT8870 and checks it with our defined function saved in its memory. According to operation has to be done, micro -controller sends a signals to the motor driver IC L293D which drives the motor. And with the help of motors the robot move Forward, Reverse, Left, Right or Stop.un’s position shifts with the seasons.


  1. It is overcome the limited  range of wireless working like with RF. Thus its provide wireless controlling Robot without any limited range.
  2. User can also use multimedia cell phone for video calling and easily can get video output from robot.
  3. Easy to apply with any phone.


  1. Mobile battery gets discharge while operating. Thus have to charge battery time to time.
  2.  As it is work with mobile calling, thus it generate high mobile bill.
