A Navigation Platform assists individuals whose degree of disability is high. In this paper a low cost auto-navigated wheelchair is designed for patients suffering from paraplegia or quadriplegia (paralysis caused by illness or injury), which uses cheaper components that assists navigation. Here a comparative study on fixed path navigation is done in embedded platforms such as Arduino and Raspberry Pi. The design works on the principle of Distance Estimation. The distance estimation is done with the help of rotation encoder with MOC 7811 IC with the pulse counting circuit placed at one of the wheelchair motors. The comparative study shows that in terms of controlling extra hardware the better performer is the Arduino platform as compared to the Raspberry Pi platform, whereas for compiling bigger algorithms Raspberry Pi is better. Various test runs were conducted by navigating through different rooms in a building and the results were plotted by using both the platforms.
