Smart Autonomous Wheelchair Controlled by Voice Commands-Aided by Tracking System


This study focuses on the design of an autonomous wheelchair basedsmart driving features for disabled persons. The movement directions andposition tracking of the wheelchair are controlled and localized by pre-definedvoice commands and global positioning system (GPS), respectively. Arduinomicrocontroller based on speaker dependent voice recognition module andtracking system based on quad-board SIM808 has been used to help thewheelchair navigation. The experimental tests of the proposed system have beendone and given satisfactory results in controlling the wheelchair and making acall on demand. Hence the proposed system is a simple, easy to use and lowcosthardware for designing.
