We know that sound is a form of energy that creates in us a sensation of hearing. Being a mechanical wave sound traverses through the medium creating vibrations in form of compressions and rarefactions. Auditory receptors have the capability to trap sound by perceiving the vibrations created in the medium during propagation of sound waves. And yet another technology comes using sound as a medium of wireless transmission for controlling the movements of a quadcopter.
A quadcopter is a four rotor multi-copter generally possessing four different motions viz. throttle, elevator, aileron and rudder. In case of a normal quadcopter these motions were controlled by the help of a 6 channel radio control transmitter and receiver. In this model a voice recognition module is used as the receiver which is being operated by the voice of the operator. the voice recognition module is connected to an Arduino board which is the control unit of the copter. the data transmission is the very well known serial transmission. The commands are set by the operator and whatever he/she commands the quadcopter shall operate according to it based on the program coded in the Arduino board. Serial communication helps in easy coding of the processor based on various commands that are set by the operator.
Quadcopters have got a wide range of applications these days not only in the military field as well as in household purposes such as in the delivery processes and so on. Making a quadcopter voice control will not only reduce the cost but will also make the device look cool.
