Inspired by: I HAVE BEEN NOTICING A VERY SERIOUS ISSUE REGARDING THE BLACKBOARD AND CHALK DUST.I HAVE BEEN WATCHING TEACHERS,PROFESSORS SNEEZING AND COUGHING WHILE ERASING THE BLACK BOARD DUE TO THE CHALK DUSTWHILE ERASING THE BLACKBOARD,CHALK DUST WHICH IS AN IRRITANT,STAY SUSPENDED IN ATMOSPHERE AND THEY CAN BE EASILY CARRIED AWAY BY AIR TO A GREATER DISTANCE -IN EQUIPMENTS AND DIRECTLY IN TO OUR LUNGS WHILE BREATHING.CONSIDERING ALL THE ABOVE POINTS,I CHOOSED TO DEVELOP THIS METHOD WHICH WILL MAKE TEACHERS AND PROFESSORS LIFE MORE EASY WHILE ERASING THE BLACK BOARD WITHOUT FACING ANY PROBLEM REGARDING CHALK DUST.
TO SOLVE THIS KIND OF PROBLEM,I DEVELOPED A ELECTRONIC MOTORISED MECHANICAL BLACK BOARD ERASER [EMMBBE] MECHANISM, WHICH WILL BE MOUNTED ON BLACK BOARD AND WOULD PERFORM VARIOUS ERASING OPERATIONS WITH THE HELP OF DUSTER, ,WATER SPRAY ATTACHED TO THAT MECHANISM.
