Voice Controlled Robotic Car using Arduino

The project entitled “Voice Controlled Robotic Car” aims to build a car that reacts in accordance to the corresponding voice command of the user. Simple voice commands like left, right, forward, back, and stop is used for various movement of the car. The idea is to first design the hardware prototype and then develop the entire working code. At the heart of the car is Arduino UNO, which acts as the brain of the car. To the Arduino UNO are all the other hardware interfaced. The code is then developed, simulated, and fed to the Arduino UNO using the IDE. The car is then connected and controlled wirelessly via a smartphone. This wireless coordination is accomplished with the help of a HC-05 Bluetooth module. Voice commands are given to the robotic car via the android application installed in the smartphone Additionally, an HC-SR04 ultrasonic sensor is also interfaced, which when on detecting an obstacle stops the car, henceforth, preventing the collision.
