Smart Duster-An Automatic Board Cleaning Device

Abstract

   A trending development in technologies demands for the higher performance machine to satisfy human and market needs. In today‟s scenario, the world demands everything to be automated especially in the field of medical science, engineering and teaching fields etc. It is often seen that the boards which are used in schools and colleges are approximately 20 feet wide. And these chalkboards when completely written takes more than a minute to clean it manually. If a class continue for about one hour then about 10-12% time will be wasted in cleaning such a big board with a tiny duster. And the chalk dust obtained after erasing the board is also hazardous for human health. The “Automatic Board Cleaning Device” is a spectacular replacement of traditional duster. This project was selected by us to provide some comfort for teachers while cleaning the chalkboard. This automatic board cleaning system uses the aluminium track and wheels mechanism that moves horizontally for cleaning the chalkboard with the help of DC geared motors. It is also modified by adding a sprinkler and blower for wet wiping the board. Implementing this technique reduces the time consumption in cleaning the chalkboard manually as it can clean the board within a few seconds.
