Voice Recognition Based Multi Robot for Blind People Using Lidar Sensor

Abstract

In recent times, advancement in the Robotic industry made a huge impact on the Visual path Guiding Industry, Several Blind Assistive system is suggested by many researchers. However, Guiding through the unpredictable ambient environment is a difficult task for mobile Guiding Robots. Internet of Things (IoT) enabled Robot Control is seen as a more flexible and effective communication medium in the Robotic Industry. In this paper, we are suggesting RTOS (Real-Time Operating System) enabled Smart and Multipurpose voice recognition Guiding Robot to guide visually impaired people to Locally Programmed Destination. This Robotic Dog Capable of Recognizing Word Spoken by the User by using Google Voice Recognition API and Operate depend upon the Voice Commands. This Robotic Dog uses Light Detection signals to detect the Obstacles placed in the traveling path. Also, it uses Corner Crossing Algorithm to intelligently avoid the Corners in Operating Environment. This robot having “Watchdog” mode with this mode act as a Watch Dog and will warn a user if there is any abnormal Movement also featured with Fire Sensor. The robot was designed with a self-charging feature, in normal daytime, it can capable of finding the sunlight by moving around the working location and charge by itself using photovoltaic cells.
