Voice Control Robotic Car

Abstract: This project aims to design and implement a voice-controlled robot car using an Arduino microcontroller. The robot car is controlled through voice commands via a smartphone app. providing a hands-free, intuitive driving experience. The system integrates an Arduino board with a Bluetooth module (HC-05) for communication, a motor driver (L298N) for controlling the motors, and a smartphone app with voice-to-text functionality. The user issues commands such as "forward," "backward," "left," "right," or "stop," which are processed by the smartphone app. These commands are sent to the Arduino, which then drives the motors accordingly. The project leverages the flexibility of Arduino and voice recognition technologies to allow for seamless interaction and remote operation of the robot car without the need for manual input, enhancing the user's convenience and making it suitable for various applications like automation, remote control vehicles, and robotics education. In this paper, we describe the hardware and software architecture, voice recognition algorithms, and demonstrate the working prototype of the voice-controlled robot car. The project showcases the potential of combining voice control with robotics and presents a user-friendly solution for controlling mobile robots.
