DTMF Controlled Wireless Robot

DTMF Controlled Wireless Robot” is capable of receiving a set of command (instructions) in the form of DTMF tones and performs the necessary actions. Here DTMF stands for “Dual tone multiple frequency”. We will be using a dedicated modem/mobile at the receiver module i.e. with the robot it self and send the commands using DTMF tones as per the required actions.

The mobile unit which is dedicated at the robot is interfaced with an intellectual device called Microcontroller so that it takes the responsibility of decoding the tones received and perform the corresponding predefined tasks such as move front or back, left or right etc.

The micro controller is also interfaced with few DC motors in order to move the robot in different directions. The ON and OFF of the DC motors depends on the direction it has to move which is the complete responsibility of the controller to take those intelligent decisions.

The major building blocks of this project are:-

• Regulated Power Supply
• GSM Modem/Phone
• Microcontroller based Control Unit
• Robot Mechanical Assembly
• DTMF Drivers
