An IoT based Interactive Speech Recognizable Robot with Distance control using Raspberry Pi

It is not convenient to use custom controller for operating a robot car and most easy way to control a robot is definitely with voice. In this paper, we have propounded a voice recognition based system where controlling process will be very much expedient to use. In our speech recognition based Robot car, anyone can easily control the system with his voice command and can also manage the robot to cover a guesstimate distance. For recognizing the voice, we are using Python speech recognition module and the most interesting thing is that the system can be configured with approximately 119 languages without much hazard. It can handle four different basic movement commands and the key feature of this system is that, if the user wants to run the system with a certain distance, the system can recognize that also. The system can detect human existence and the human detection part is handled by the ultrasonic sensor. The robot car will be automatically stopped by sensing obstacle if anything on its way and this obstacle detection process is handled by the ultrasonic sensor. All the system is controlled from a single board computer named Raspberry Pi 3 and the voice speech is recognized using Google speech reorganization engine.
