This paper proposes NLP based system to facilitate user interaction by verbal communication in a seamless manner. With the advancement of technology the human machine interaction becomes an unavoidable scenario. Introduction of natural communication is an addition that has to be made sooner or later in every department. Devices that accept interaction based on Natural Language, like, using voice commands, can understand basic human orders or answer questions whenever user expressions fit into the known language pattern. The purpose of this work is to introduce a system which is capable of interacting with human and is able to assist them using authentic knowledge and provide a smooth experience.
Voice Controlled Robotic Vehicle is an example of controlling the bot with the help of daily used voice commands. An Android app is used for giving input voice commands and in order to control the motion of robotic vehicle. The voice commands given by us is processed by the app and voice module converts speech into text. A controller should be implemented with a Bluetooth module through the UART protocol. The converted text commands reach the controller via Bluetooth. The microcontroller will process this text and take a necessary action to control the motion of the robotic vehicle. The hardware development board used here is Atmega Arduino Board. The software programming part is done in Arduino Ide using Embedded C. The objective of the project described in this paper was to regulate the movement of the robotic vehicle using commands such as Forward, Backward, Left, Right. There is still a plenty of scope for research and development in the project described in this paper. Adding a very small size camera and using http communication protocol we can receive video streaming from the camera which is placed on the robotic vehicle. The Robotic vehicle now can be used for surveillance of terrorist prone areas, suspected areas.
