A Novel Voice Controlled Robotic Vehicle For Smart City Applications

Abstract

There are a lot of researchers working towards enhancing the connection between humans and robot. In this article, we have developed a robotic vehicle which can be controlled by voice commands. The control system of the robot movement will respond to the voice of the commanding person. A Texas board, MSP432P401R is connected to TI-RSL (Texas Instruments-Robotic System Learning) kit and used together with Wi-Fi module, CC3100 booster pack interfaced to an android application IFTTT (If This Then That) and Blynk to transmit the voice commands. The proposed system is designed based on microcontroller (MSP432P401R) which is connected to smart android phone through Wi-Fi module for receiving voice commands. The voice commands are converted to text by an android app and sends necessary data to the controller for robot movement. The voice commands are processed in real-time, using an online cloud server called Blynk. After receiving each command from the controller, the TI-RSL kit responds and moves in the desired direction. Moreover, we have also used camera module to watch the live streaming and direct the robotic vehicle without facing any obstacle. The camera is interfaced with Raspberry Pi for live streaming. The purpose of our article is to use this robotic vehicle in high toxic areas, where human cannot reach but human voice can.
