Cell Phone Controlled Robotic Vehicle
The project is designed to develop a robotic vehicle that is controlled by a cell phone. DTMF commands from a phone are sent to another cell phone which is mounted on the robot. These commands are fed to a microcontroller of 8051 family to operate the vehicle movement through motor interface.
The main scope of project is to send commands from one cell phone to be received by another cell phone mounted on the robot to receive the DTMF (Dual Tone Multi Frequency) mode commands which are then decoded by a DTMF decoder.
The corresponding codes are then fed to a microcontroller, programmed to recognize those codes to operate 2nos DC motors through motor driver IC for any direction movement as per the sent commands from sender’s mobile. The motors are controlled using motor driver IC which is interfaced to the microcontroller. It uses microcontroller from 8051 family and a battery for power source.
Further the project can be enhanced by interfacing it with additional motors for multipurpose activity. For example, it can be developed into pick n place robot or fire fighting robot with water pump etc.
1) This line following robot can also be modified to a walking robot in any surface by using only one motor with homemade fixtures as per the detailed instructions give.
2) Similarly the same walking robot can be attached with special magnetic material as per instructions to climb a wall of any vertical metallic surface say a refrigerator body.

"I live in Hyderabad, a place that is known for engineering colleges. Went with frnd and bought a set from Ameerpet(tht hs rdymade stuff like this) and it failed just b4 viva. Thats when we got this thx to a senior who is sorta like a geek.. and let me tell u.. Its one reason why me and my frnds got thru the final sem. Works great and is useful too later.. "Ravi Teja

"A must-buy. It helped me practice in real time and learn how to make a project by looking at an actual workable unit. (fyi - you get a fully built unit and another full set of components to build another by yourself) so it was great value for us. We shared the costs by 3 (our team for the project) but i got to keep my unit as the other two kept the original. Showed it for my on-campus and got thru too becuase it not just looked neat and profesionally bt worked great later. (still have it in my room, now working with GE in Bangalore) "Anusha

"We have used it for our institution - it is available in lab and has been good for explaining various models in live during class. Strongly suggest every college dept to have it for labs as it is working well - even with regular use at lab for more than 1 year. Note:We got the unit complementarity before launch in 2014 and have later purchased few batches. The team behind it is professional and know what electronics students need and i am writing this review on their request on 13/05/2016"Mr. Ramesh Kumar Jha

Q: Which microcontroller is used in this project?
A: A 40 pin microcontroller from 8051 family is used in this project.
Q: Can this project be implemented using the landline phone?
A: No, this project has been designed to be implemented with only a mobile phone.
Q: What is DTMF?
A: DTMF or Dual tone multi frequency is a signaling system which uses a combination of two frequency tones to represent a key pressed on the keyboard of any cell phone.
Q: What are keypad tones?
A: Keypad tones are the audible sound heard, when a key is pressed on the mobile phone.
Q: How to set the keypad tones?
A: Go to sound setting->tones->keypad tones->volume maximum
Q: Which DTMF IC is used?
A: IC 8870 is the DTMF IC used
Q: How can one control the robot?
A: One can control the robot remotely or directly connecting the cell phone using a 3mm audio jack.
Q: Can this project be implemented using any kind of mobile phone?
A: Yes, this project can be implemented using any kind of mobile phone, supporting a 3mm headphone jack.
Q: Why my phone is not working for the project while it works with other phones?
A: The dialing tones generated by a phone forms as an input to the project for proper working. While some phones develop exact DTMF tones even before establishing a call while pressing the numbers, some other phones develop a flat tone for any number pressed. Besides the same, some phones the internal speakeroutput is not disabled owing to some specific setting enacted by the user. In these cases directly dialing through chord connection shall not work. However if a call is initiated to the dialed number mobile which is interfaced to the project it will work (provided the connector is not loose) as DTMF tones are compulsorily made available to the receiver from the exchange ,as all our IVRS works on those kind of tones. Therefore,if the project does not work by direct wire connection please try by dialing the number from any other phone. In order to be doubly confirmed make sure that while one inserts the pin to the cell phone the speaker gets disconnected failing which it is not going to work because the tones are sent to the project board only if the speaker of the cell phone is disabled.
Q: What is the motor speed?
A: Motor speed is about 45RPM.
Q: What is the remote access?
A: Controlling the robot by establishing a call with the connected mobile phone is remote access.
