Voice-Controlled Robot using Arduino and Bluetooth

This paper proposes a voice-controlled robotic system that uses Bluetooth to follow human commands. The voice commands are given to an android app built using MIT App Inventor. These commands are then sent to the Bluetooth module which then sends them to the controller interfaced with it. This interfacing was done using Universal Asynchronous Receiver-Transmitter (UART) Protocol. After processing the commands, the microcontroller controls the movement of the robot in different directions. An open-source hardware and software is used in the proposed research work. Further, the proposed model can be implemented by almost every student for educational and understanding purposes as it is both economical and easy-to-use. This study considers the domain of Natural Language Processing (NLP) as well as communication using Bluetooth, both of which have high possibilities in future based on the technological advancement.
