The Voice Controlled Robot is controlled via voice commands given by the user operating the project. These voice commands must be given through an Android application that is installed on the mobile of the Android user. Keep in mind that the user must have a good Internet connection to have a smooth operation of the Android application. Voice recognition is performed within the android application and then a respective command is sent to the voice controlled robot vehicle. The microcontroller mounted on the Robot decodes these commands and gives an appropriate command to the motors connected to the robot.
In the voice manipulation robot the movement of the robotic vehicle controlled by voice command. This is the basic android project. In this project we use the Bluetooth device to receive the command of the user. The user uses the android application to give the command to the Bluetooth device. The Bluetooth device receives the command from the application and transmits the same to the microcontroller 8051 and then to the microcontroller that controls the robotic vehicle according to the command. The microcontroller is the main unit of our project. It is a central processing unit (CPU) of the Robot. Receives several commands from the BLUETOOTH decoder and gives the respective output motor excitation circuits
This robotic vehicle operated in command 7 as forward, reverse, left, right, stop, left turn U, right turn U. This project uses the 8051 microcontroller after receiving the above command from the microcontroller to move the Motors according to the command. Communication between the Android application and Bluetooth is serial communication. Here we use LCD screen for the project title that shows also shows different commands given by the user.
In this project, the robot is controlled by the Android mobile phone that connects to the Bluetooth decoder connected to the robot. Therefore, we need 1 mobile decoder and 1 Bluetooth. The Bluetooth decoder is always connected to Robot and another mobile phone is used to control the movements of the Robot. It consists of Bluetooth decoder. Output ASCII code. This receiver allows the wireless transmission and reception of serial data. It is 10 meters wide. DC motor used for the movement of robotic vehicles.
