Download Automatic Whiteboard Eraser Interfaced Using Assembly Language
Transcript
For automatic erasing: S2 = d2/tave2 = 1.6256 meters / 29.0812 sec S2 = 0.0559 m/s In this computation, manual erasing is faster than automatic erasing considering the distances and the time consumed to erase the contents of the board. This test shows that manual erasing is faster than automatic erasing. However, the speed of the design project is a minor factor to be considered. The time consumed by the user to push the buttons to use the automatic whiteboard eraser, which takes less than 2 seconds, is the important factor to be considered in this design project. The user does not have to waste time and effort in doing manual work. The automatic whiteboard eraser will do the erasing job while the user can continue his/her work. Part 4: Determining the appropriate size of the whiteboard The designers previously used larger whiteboard with dimensions of 46” x 24” with a larger frame with dimensions of 61” x 48 ½”. However, numerous problems were encountered. First, transporting the prototype was a nuisance since it could only fit in a van. Second, not all the areas of the whiteboard could be erased—considering the position of the DC motors and the length of the previous conveyor belt. There was so much space wasted on the sides of the board that is almost 5”. In order to lessen these problems, the 46” x 24” board 44 | P a g e
