White board cleaner

Description

The work presented on this paper is a design and fabrication of an automatic white board cleaner The objective is to reduce the man power involved in cleaning in white board. Through the increase of smart boards have increased the need for these automated white boards has rapidly grown. The white board operate analogously to the chalkboard in that they allow markings are made. In later 1980’s these automatic white boards cleaners started existing in the market. They were also called (marker boards) The first white board cleaner was very expensive and was not affordable by everyone so the new experiments began making the white board as simply and cheaper as possible. The design of developing an white board cleaner is mainly with the aim of reducing manpower in erasing a white board.by using these automatic machines we can clean the white board automatically with few seconds and save a lot of time. The system is designed in a way that it can clean both black board as well as white board. In this the duster is very long and placed vertically with the white board. The duster is connected across the wheels across both the ends. These wheels move by the mechanical action of an D.C motor and as the duster moves to and fro of the white board and cleans it. This device also has 2 surfaces one is for rough surface and the other for white board cleaning includes the instruments like sensors ,indicators and an flip mechanical component that is used to flip the duster on basis of board its cleaning. The main motto of this automatic machine is to clean the board as soon as possible so that a lot of time is saved and manpower is conserved. The another intention of developing this board cleaner was to reduce health hazards. From chalk dust a lot of disturbance is caused in class as well as with the health of the faculty and children.so the concept of automatic white board was introduced.

The exiting solutions for the given problem There are many white board cleaners available in market. The need for this technology is increasing gradually The number of the white board cleaners are of many types. They include moving rover cleaners, automated machines connected to the boards and operated by dc motors and Arduino boards.List of some exiting solutions available:

Back ground of the project:The system is designed in a way that it can clean both black board as well as white board. In this the duster is very long and placed vertically with the white board. The duster is connected across the wheels across both the ends. These wheels move by the mechanical action of an D.C motor and as the duster moves to and fro of the white board and cleans it. This device also has 2 surfaces one is for rough surface and the other for white board cleaning includes the instruments like sensors, indicators and an flip mechanical component that is used to flip the duster on basis of board its cleaning. The cleaning process takes less than 10 seconds for completion of the process.the materials required are many. Some of the materials are as follows: *Design of the model *Selection of components *Manufacturing and assembly *Testing *conclusion
