Working of Voice controlled drone
Block diagram for Voice control System of UAV
Electronic Speed Controllers The function of the electronic speed controllers is to get the output signal from the flight controller and precisely control the speed of the motor. Battery Lithium Polymer batteries are used in drone. These cells can produce an enormous amount of current, needed for the brushless motors. These batteries are rechargeable, can last longer, have low weight and high voltage capacity compared to other type of batteries. Flight Controller A flight controller is a microcontroller in which suitable sensors and RF module are interfaced in order to control the
RF module The RF module consists of an RF Transmitter and an RF Receiver. The transmitter and receiver (Tx/Rx) pair operates at a frequency range of 434 MHz. An RF transmitter receives serial data and transmits it through Radio Frequency through its antenna. Electronic Components Connection The four motors are controlled by Arduino controller through four ESCs. As two motors should spin in clockwise and other two should spin in anticlockwise direction, the positive and negative wiring from motor to ESC is checked for its direction.
Voice Commands For Drone S.No Voice Commands Actions (^1) Start Motors Motors start spinning, maintaining middle speed (^2) Fly Low Speed of motors decrease and vehicle (^3) Fly High Speed of motors increase and vehicle goes up faster (^4) Go Left Right portion of motors increases speed (^5) Go Right Left portion of motors increases speed (^6) Go Forward Left portion of motors increases speed (^7) Go Backward Left portion of motors increases speed (^8) Turn Left Counter clockwise motors increases speed (^9) Turn Right Turn Right Clockwise motors increases speed (^10) Hover Speed of all motors is uniform and thrust
