This paper introduces an intelligent and efficient path guidance robot to assist the visually impaired people in their movements. This is a novel device for the replacement of strenuous guide dogs. The robot has the capability to move along multiple paths and then remember as well as retrace all of them, thus making it a perfect substitute for a guide dog which is often a luxury for the ninety percent of blind people living in low income settings. The robot is capable to guide the user to travel places which cannot be traced using GPS. Since most of the navigation systems that are developed so far for the blind people employ a complex conjunction of positioning systems, video cameras, location mapping and image processing algorithms, we have designed an affordable low-cost prototype navigation system which serves the purpose of guiding the visually impaired people both in indoor as well as outdoor environment.
