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.

How To Choose Best kit for You

1. Professional Kit

this kit for Professional person who knows project soldering, testing, assembling and some basics knowledge. In this kit our role is to provide PCB fabrication, microcontroller programming (If any), Project designing and documentation. Our responsibility is limited to according to checklist facilities only. User is responsible for further process like soldering, assembling etc to complete the project. (Do it yourself 70%)

2. Assembled kit

this kit is fully assembled and tested by us for final running. It has prepared for instant requirements and Ready to Use

3. Combo Kit

there are two separate kits, one fully assembled and tested kit. The second one is a Designed & Drilled Copper PCB with soldering components except a set of detachable components which is already attached in first kit (assembled). User can complete the second kit according to assembly procedure given by us in their college practical lab. If user could not complete their project then he/she can use our first kit or make correction by analyzing and comparing with first kit. (Do it yourself 50%)

4. Learning Kit

this kit is fully Do it yourself under our live guidance & support at our workshop or online video calling. We guide how can component has to be place on PCB and solder to it. We continuously checks and guide if any mistaken by user step by step till completion of project. And after successfully completion of project we certify to student that he/she complete their project successfully in our guidance and also provides our company certificate for this.
