A robot control device, abnormality diagnosis method, and non-transitory computer readable medium are provided. The robot control device () performs abnormality diagnosis of a robot body () including a motor () that rotates, from a starting angle position to a target angle position, a rotational shaft () for transmitting power to an arm () so that the arm performs a predetermined operation. The robot control device includes: a drive control unit () driving the motor so that the rotational shaft rotates from the starting angle position to the target angle position within a rotational speed range of the rotational shaft in which it is possible to detect a vibration component caused by an abnormality from among the vibration components generated along with the rotation of the rotational shaft; a vibration detection unit () detecting the vibration component; and a diagnosis unit performing abnormality diagnosis based on the detected vibration component.

Degradation degree of a bearing mechanism is diagnosed. A diagnosis apparatus includes: an acquisition unit that acquires measurement data relating to vibrations corresponding to a rotation of a bearing mechanism including rolling elements between an outer ring and an inner ring; an extraction unit that extracts a feature amount from a result of performing a frequency analysis on the measurement data; an estimation unit that estimates a size of a scratch generated on the outer ring or the inner ring based on a predetermined relationship between a change of the feature amount and a size of a scratch generated on the outer ring or the inner ring, and based on the feature amount extracted by the extraction unit; and an output unit that outputs an estimation result of the estimation unit.

A processing machine processes a work and repeats processes on the work, thereby consuming energy. Within the consumed energy, room for improvement is computed by an energy monitoring device and is referred to as an amount of energy that can be improved. An energy monitoring device includes a power data acquirer that acquires a time-series power data measured by a power meter, a cycle detector that detects a single-cycle power data from the power data acquired by the acquirer, a divider that divides the single-cycle power data detected by the detector into an added-value creating portion and an unproductive portion, and a computing unit that computes an amount of energy consumed in the unproductive portion divided by the divider and defines it as the amount of energy to be improved.
