Voice control robot is just a practical example of controlling motions of a simple robot by giving daily used voice commands.
In this project, the user gives specific voice commands to the robot through an Android app installed on the smartphone. At the receiving side, a Bluetooth transceiver module receives the commands and forwards them to the microcontroller on the robotic car.
The Microcontroller controls the movements of the robot according to received commands. The robot moves forwards, backwards, left and right, and stops according to the voice commands forward, backward, left, right and stop, respectively.
