A Voice-Controlled Car is a robotic vehicle that can receive spoken commands and convert them into driving actions. A microphone or voice-recognition system captures commands such as forward, backward, left, right, and stop. A microcontroller processes the command and controls the motors through a motor driver, allowing the car to move according to the user’s instructions.
Voice-controlled cars are useful for robotics education, assistive technology, automation, and smart transportation experiments. They demonstrate how voice recognition, embedded systems, sensors, motor control, and wireless communication can work together in a robotic system. With additional sensors, the car can also detect obstacles and improve its ability to navigate safely.
