It is a system that is generally used to clean the whiteboard automatically with the help of duster. By the use of this automatic system we can save our time and energy. It is a new technology that is generally used now a day. A system for cleaning the whiteboard wherein a duster is mounted for longitudinal movement on the board and a hand wheel is mounted that is mechanically interconnected to a drive assembly for producing the movement of the duster in an erasing operation. It will use the bevel gear, chain and sprocket mechanism to convert the rotary motion of hand wheel into linear motion of duster.

2. The main aim of our project is to save time and
energy. In earlier days writing is done on sand, slate,
walls, and chalkboards. It’s highly impossible to
spend our time always in cleaning of the board and
absorbing dust. Instead of this, we can use
automatic board cleaner.

3.  This indeed saves our valuable and precious
time.
 We can do the cleaning work, merely by using
automatic board cleaner.
 It is highly useful, as it possess various
advantages.

4. 1. It’s construction is simple and requires less
maintenance.
2. Low cost.
3. Portable in size and easily transportable.
4. Less manual work.
5. Time saving project.
6. No external devices are used here to control it.
7. Useful in college and school applications.

19. As conclusion, an automatic whiteboard cleaning
machine was designed and fabricated using low
cost material and with user friendly interface. This
machine can potentially be used in class rooms to
assist the teacher in keeping the whiteboard
cleaned. The result obtained from this research is
such that it operates in the range of 20m and takes
just 4 seconds to clean the whole board. This
research fully concentrates on the energy saving
mechanism. In future this work can further be
modified by using motors, sensors,
microcontrollersetc.
