Slip detection using acoustic emission signal analysis

Abstract

The detection of the onset of motion and slip between an end effector and workpiece has been of interest for some time and many schemes have been proposed. This paper reviews some of the background on slip detection methods and proposes use of acoustic emission signal analysis a slip detection technique. The genesis acoustic emission during slip is discussed and experimental evidence presented to the sensitivity of acoustic emission to slip between two surfaces. Preliminary tests with a robot gripper have also done to demonstrate the feasibility of acoustic emission slip detector.
