The
main aim of this project is to design and construct an automatic robot which is
capable of receiving a set of command instructions in the form of DTMF tones or
voice commands using voice recognition system and performs the necessary
actions. Here DTMF stands for “Dual tone multiple frequency”. Also the Robot is
designed with additional features like RTC (Real-Time Clock) to display time
and Ultrasonic sensor to detect the obstacles.
This project makes use of a voice
recognition system to recognize the voice commands given by the user for the
Robot direction movements. Also to switch the mode from Voice mode to DTMF mode
by the voice commands only.
