Voice Control Robotic Vehicle

Voice Control Robotic Vehicle

Voice controlled robotic vehicle by using android application

Robots are smart machines that can be programmed and used in many areas such as industry, manufacturing, production lines, or health, etc. By the developments of communication technologies in the last era speech starts to be an important interface for many systems. Instead of using complex different interfaces, speech is easier to communicate with computers. 

So here we introduce voice control robotic vehicle and the robot is able to recognize spoken commands to move correctly. To give a direction to robot, first the voice command is send to the computer using a microphone. The computer recognizes the command by speech recognition system. And then computer converts the voice command to direction command that predefined and recognizable by robot. When the robot gets the direction command, it moves according to spoken commands.

Block diagram:-

In the system First the Bluetooth module HC05 will receive the  voice command from the android application And it will give this command to micro-controller with the help of speech reorganization for processing the robotic vehicle.

The android device sends voice commands to move the vehicle in forward, backward, right and left directions. After receiving the voice commands, the microcontroller then operates the motors IC order to move the vehicle in four directions. The communication between android device and receiver is sent as serial communication data. The microcontroller program is designed to move the motor through a motor driver IC as per the commands sent by android device.
