The Fume Detecting Dual Tone Modulation Frequency Based Rover Using Brushless Direct Current Motors

The purpose of this project is to improve the control and precision of any rover by replacing the convention direct current motors or servo motors with brushless direct current motors. The BLDC motors are much accurate to control because of the sensors they are equipped with. The telephonic signal from the transmitter generates two frequencies one is a lower frequency and the other is a higher frequency. The higher frequency is used to drive the motors. The signal is then sent to the receiver which then transmits the dual tone modulation frequency signal to the DTMF decoder. The DTMF decoder then decodes the received signal and then transmits to the gate driver IC (which is connected to the Arduino for motor control). The Gate Driver IC which has the BLDC motors connected to it drives the motors. Furthermore this rover is being operated by Dual Tone Modulation Frequency (DTMF). In addition the rover is equipped with a Gas Sensor.
