Fingerprint Sensor Testing Using Force Feedback Control

University essay from Lunds universitet/Institutionen för reglerteknik

Author: Viktor Johansson; [2016]

Keywords: Technology and Engineering;

Abstract: Testing and validation of fingerprint sensors with human labor is time consuming, costly and lacks the speed, accuracy and repeatability required for sufficient results. The thesis investigates the possibility of an automated solution using an industrial robot with force feedback control. Several force feedback controllers are implemented and evaluated. The best controller is implemented together with a graphical user interface and programming of an industrial robot manipulator. The setup can successfully test multiple sensors and display pictures taken with a fingerprint sensor, together with the applied force.
