Abstract [en]

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.

Abstract [sv]

Whiteboard är ett verktyg som används i flera olika fastigheter runt om i världen. Att ta bort bläcket från whiteboarden kan dock vara onödigt tidskrävande och distraherande. Syftet med projektet var därför att automatisera processen med några begränsningar. Två begränsningar var att prototypen skulle väga lite och vara tillräckligt liten för att vara handhållen. En annan begränsning var att den skulle fungera korrekt på en magnetisk yta.

För att konceptualisera syftet byggdes en prototyp med en iterativ process och därefter programmerades den för att få en systematisk rörelse. Den utnyttjade kontinuerliga servomotorer, IR-sensorer och ett 3-axligt gyroskop i kombination med 3D-printade komponenter.

Den slutgiltiga prototypen visade sig fungera korrekt men kan förbättras eftersom dess raderingsegenskaper inte fungerar som man kunde ha förväntat sig från en färdig prototyp.
