CELLPHONE CONTROLLED ROBOT

INTRODUCTION

• Wireless controlled robots user circuits, which have a drawback of limited working range, limited frequency range and limited control.

• Use of mobile phones for robotic control can overcome these limitations.

• It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls.

• If any button is pressed a tone corresponding to the button pressed (DTMF TONE) which is processed by the microcontroller with the help of DTMF decoder IC CM8870

• This IC sends a signal to the the motor driver IC l293D which drives the motor forward, reverse, left or right.

CELLPHONE CONTROLLED ROBOT

APPLICATIONS

SCIENTIFIC USES: Including hazardous environments, working in the deep ocean and space exploration

MILITARY AND LAW ENFORCEMENT : The exposure to hazards are mitigated to the person who operates the vehicle from a location of relative safety. Remote controlled vehicles are used by many police department bomb-squads to defuse or detonate explosives and can also provide surveillance capabilities

SEARCH AND RESCUE : This was demonstrated by the successful use of UAVs during the 2008 hurricanes that struck Louisiana and Texas.

RECREATION AND HOBBY : These include on-road cars, off-road trucks, boats, airplanes, and even helicopters.

ADVANTAGES The following are the various advantages of this sytem: 1.Wireless control 2. Surveillance System.

3. Vehicle Navigation with use of 3G technology.

3. Takes in use of the mobile technology which is almost available everywhere.

4. This wireless device has no boundation of range and can be controlled as far as network of cell phone

DISADVANTAGES

CELLPHONE CONTROLLED ROBOT

The Disadvantages of the system are as follows: 1.Cell phone bill.

2. Mobile batteries drain out early so charging problem.

3. Cost of project if Cell phone cost included.

4. Not flexible with all cell phones as only a particular ,cell phone whose earpiece is attached can only be used

FURTHER IMPROVEMENTS

FURTHER IMPROVEMENTS AND SCOPE: IR SENSORS : IR sensors can be used to automatically detect & avoid obstacles if the robot goes beyond line of sight. This avoids damage to the vehicle if we are maneuvering it from a distant place.

PASSWORD PROTECTION : Project can be modified in order to password protect the robot so that it can be operated only if correct password is entered. This introduces conditioned access & increases security to a great extent.

ALARM PHONE DIALER : For example, a high water alarm, low temperature alarm, opening of back window, garage door, etc.

ADDING A CAMERA : Robot can be driven beyond line-of-sight & range becomes practically unlimited as GSM networks have a very large range.
