The aim of this paper is to present the analysis of experimentally collected data acquired from the rotating shaft. The shaft surface was sensed by the non-contacting eddy-current probe using the home made robot. The robot consists of the controlled round table for object positioning and controlled arm for sensor. Two stepper motors are employed to control the movement of the probe in two perpendicular directions. The third motor drives the table with the rotor. The stepper motors are controlled by the micro-controller programmed from the PC. Using the probe and sensing the shaft surface pattern it is possible to …
