Automated Motorized Whiteboard

Teaching and learning processes in schools and colleges have been continued from the past. Different methods of writing on boards and cleaning the boards have been developed. This paper presents the design and construction of automated motorized whiteboard. The system consists of four basic units: Flexible whiteboard surface material, dusters, plastic rollers, motors. The working of this system is based on rotation of flexible whiteboard surface material around the rollers and automatically cleaning the surface by the dusters fixed on the back side of the board. The system makes teaching efficient and reduces human efforts. The history of teaching starts from the very beginning of mankind. Knowledge was passed down from generation to generation. The materials used in teaching also got advanced along with the teaching and learning methods.Writing was earlier done on sand, walls, slates made out of wood, chalkboards and in recent times on white boards and electronic boards (2). The white board has been largely adopted into many other sectors of human endeavour besides teaching because of its many advantages over the chalkboard (4), (5).Motors has huge applications in the field of automobiles and robotics. Other applications include home appliances and various fields of mechanical sector. In this paper the design and implementation of motorized automated whiteboard is presented as an introduction to the automation of the teaching process easing and reducing the task of clearing the board as it cleans itself by rotation of whiteboard surface and the dusters fixed at the rear side of the board. II. Related Work Researches and experiments had been done on white board from a long time. Many modifications had been done on cleaning of whiteboard surfaces. Mostly whiteboards are cleaned with the help of hand dusters but further innovations in this field have made the cleaning system easy. Remote control motorized cleaners are made in which the dusters are operated with the help of remote control (2). This type of cleaner moves horizontally by means of motor mechanism and erase the board with the help of dusters attached to it but there are some limitations in above design. The pressure is to be applied on the moving dusters for proper rubbing of the board and user have to wait till the cleaner comes to its initial position. These limitations have been overcome by the proposed design in this paper. Instead of moving the dusters the whiteboard surface is moved around the rollers. So there is no need of providing the external pressure on the dusters as they are already fixed at the rear side of the board with certain amount of pressure. The friction produced between dusters and surface will erase the written data on it.
