Running the Launch File

To start the voice-controlled robot, run the following command:

The above command will open gazebo classic and spawn the differential drive robot in a custom world ready to be controlled by voice commands.

Acceptable Voice Commands:

The system recognizes the following voice commands:

• "move forward"
• "turn left"
• "turn right"
• "stop"
• "move backward"

You can also give multiple commands in a sentence and robot will follow those in the given sequence. Eg:

• "Turn right and then move forward"

Make sure to speak clearly for better recognition performance.
