The Vibration Analysis and Signal Processing for Gas Mass-detector by End Effectors Sensor on Mechanical Robotic Manipulator

Abstract

This paper presents a system design of mechanical robotic manipulator with its own sensor end effectors. For the end effectors, they would be fixed with a fabricated micro-nano sensor. This system’s application is to detect gas density and recognize the unknown gas at the target place by executing a robotic arm action. The gas to be detected is driven to the sensor surface, and the sensor surface’s vibration signal is tested. So the paper includes the mechanical modeling of the robotic arm, and the device fabrication of the end sensor, the material vibration analysis, and the vibration signal process. In our paper we use this system to conduct NO2 measurement. Finally, the system and the gas sensor’s overall performance is summarized and discussed.
