Automatic Whiteboard Eraser : A systematic and automated process

Abstract: The whiteboard is a tool being used in several different facilities around the world. However, erasing the ink off the board can be unnecessarily time consuming and distracting. The purpose of the project was therefore to create a demonstrator to automate the process with a few restrictions. The demonstrator was required to be light enough and small enough to be handheld. In addition, the demonstrator needed to function and work properly on a magnetic surface. To conceptualize the purpose a demonstrator was built with an iterative process and thereafter programmed to get a systematic movement. It utilized continuous servo motors, IR-sensors and a 3-axis gyroscope and an accelerometer in combination with 3D-printed components. The final prototype turned out to function properly but could be improved as its erasing properties are not working as one could expect from a finished prototype.
