Automatic White Board Cleaner

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. INTRODUCTION 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. OBJECTIVE 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. ADVANTAGES It’s construction is simple and requires less maintenance. Low cost. Portable in size and easily transportable. Less manual work. Time saving project. No external devices are used here to control it. Useful in college and school applications.

19. CONCLUSION 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 .
