The device will consist of following things:-
-Erasing arm slides left to right and vice-versa on the black board erasing the written things on it.
-It has water spray mechanism which will spray a little water on the black board while erasing the black board.
-It also has a special function called as ‘skip’ which skips the particular region not to be erased and slide ahead to erase (not added in this project but can be).
-It will have hot air drying mechanism which will dry the damp black board after the use of water spray mechanism.(not added in this project but can be).
All the above function will be performed as per the user's command.
Even after erasing the black board by duster, the chalk marks on black board doesn’t seems to look completely erased which makes the black board look untidy and indistinct, eventually causing a problem for professors to again write on black board.
To make their erasing job fast, I developed a device that would erase the entire black board completely. Just by one single press of button, the device will perform it’s function which will erase the entire black board fast and make it look much clear.
Honestly speaking, so far till now, there has not been similar project unlike mine ones in the market today. The working of my project will surely gain attraction of teachers, professors and teaching institute over the entire globe.
Initially it will be manufactured on small scale and if at all its demand increases, it will be produced on a large scale.
