This study focuses on the design of an autonomous wheelchair based
smart driving features for disabled persons. The movement directions and
position tracking of the wheelchair are controlled and localized by pre-defined
voice commands and global positioning system (GPS), respectively. Arduino
microcontroller based on speaker dependent voice recognition module and
tracking system based on quad-board SIM808 has been used to help the
wheelchair navigation. The experimental tests of the proposed system have been
done and given satisfactory results in controlling the wheelchair and making a
call on demand. Hence the proposed system is a simple, easy to use and lowcost
hardware for designing.
