Automatiserad provrörskarusell : Elektronikkonstruktion och utvärdering

This thesis describes the work of an automated sample tube mover. This is a degree project and has been done at the company Q-linea AB. A carousel similar construction with a stepper motor has been designed for the task to move samples between a numbers of positions. A microcontroller has been programmed to control the movements and handle sensor data. LabVIEW have been used together with an USB-camera in order to do evaluations and tests of the system. The goal was to design a prototype that fulfills the demanded requirements of precision and timing, which also was achieved. The thesis describes the work process and concludes with recommendations for further work.
