Abstract
Methods and devices for diagnosing a robot. A method includes obtaining a spectrum of a motion signal generated by a rotating component of the robot during operation of the robot. A frequency amplitude of a sub-component of the rotating component is determined from the spectrum, based on a physical characteristic and a speed of the sub-component. A failure of the sub-component is detected by comparing the frequency amplitude with a threshold amplitude.
