The New Smart Eraser Design

The paper puts forward a kind of mechanism design scheme, the mechanism can automatically detect the blackboard chalk stains, and erase the font, keep the blackboard clean. In this paper, the hardware system and software have been connected with each other, and tell us how to get installed. It introduces the principle of the mechanism, the method of image processing, and calculates the relationship of the displacement, velocity, acceleration and structure. This wipe mechanism adopts crank slider mechanism which has a good wipe effect.
