Design and development of an automated whiteboard eraser

Abstract

The automated whiteboard eraser system using a micro plc, a DC motor for driver, a lead screw and linear bearing with drive shaft as main components. The implementation of this research consists of eight stages; i) manual sketching and modeling some ideas through literature review, ii) selected the best design and make-up the drawing, iii) categorized all components according to final design, iv) done fabrication job and bought selected standard components such as a micro set plc parts, motor driven, and electronic components, v) assembly process was done by referring the assembly drawing, vi) testing the major function of the eraser, vii) minor modification was done on the eraser system, viii) final test for overall function of the automated whiteboard eraser system. In the first stage, the manual sketches on the overall system had been done through some reviewed on the past designs or products. Earlier, Autocad 2008 software was used for modeling purpose. Then in stage two, selection of the final or the best design for this research was done according to scoring scheme. In third stage, all parts or components were categorized according to their functions and sequences. Here some parts were identified as standard components and the other parts could be fabricated on the lab. Meanwhile in fourth stage, started ordered and bought the components and parts according to the early stage task. After all components were ready assembly process was done by referring the assembly drawing. Here members in this research were worked together as a team to make sure that all parts were assembled exactly following the drawing. Then in sixth stage, testing process on the overall system was done to ensure the system totally function without any difficulties. According to the result of the testing stage, some minor modifications had done to make the system more effective. In the last stage, final test on the overall system and all minor defects were fine tuned.
