ABSTRACT: Chalkboard
erasers that are commonly used in many schools and education organizations have the poor ability in removing
the dust off the chalkboard and collect them. The dust that is not collected will
be taken into human bodies via inhalation, which will lead to respiratory diseases.
Therefore, it is crucial to design a chalkboard eraser that can collect the dust
effectively. If the eraser can be controlled both remotely and manually by people,
it can further reduce the amount of dust taken in by human bodies. To achieve remote
control, a micro-controller is needed to transfer the infrared radiation (IR) into
signals that can control electric motors to move around on the chalkboard. Furthermore,
the microfiber is also used as the cleaning material to improve the performance
of dust cleaning and collecting. A vacuum pump is needed to create negative pressure
between the eraser and the chalkboard so that the eraser can stick to it. The result
shows a stronger ability in removing and collecting dust. With the help of the Arduino
UNO board, the remote control is successfully achieved, and the eraser can move
on the chalkboard freely according to the order.
