Voice Controlled Robot Using 8051 Microcontroller

A voice controlled robot takes specified command in the form of voice. Whatever the command is given through voice module or Bluetooth module, it is decoded by the existing controller and hence the given command is executed. Here in this project, I have used Bluetooth module and Android application to give voice command in the form of hex code. There are certain digits which can be sent directly to the Bluetooth module and automatically the digit is converted into its hex code.We can use these digits as a voice command for the specified operation pre-programmed in the microcontroller.Using digits as a voice command is easier than using alphabetical commands.”
