Abstract
An industrial robot diagnostic method including performing a condition analysis utilizing at least two selected input signals, wherein each selected input signal indicates a condition related to a property of the industrial robot, performing an analysis of any combination of the selected input signals utilizing a signal modeling of the signals and outputting from the condition analyzer a result being at least one of: a detection of a malfunction of the robot system, an identification of a root cause failure in the robot system and prediction of a potential malfunction in the robot system. Also an industrial robot system utilizing the method.
Claims23
An industrial robot system condition analysis method, comprising:
- monitoring at least two selected input signals, each selected input signal indicating a condition related to a property of the industrial robot system,
- analyzing any combination of said selected input signals utilizing multi sensor data fusion of the signals,
- outputting from said analysis a result being detection of condition changes in the robot system, and
- performing a prediction of a residual lifetime of a specific component of said robot system or the whole robot system at said analyzing of said selected input signals, wherein said prediction is based on said detection of condition changes indicating a condition deterioration in the robot system.
A computer program product, comprising:
- a computer readable medium;
- and
- computer program instructions recorded on the computer readable medium and executable by a processor for performing a method
- for performing said monitoring, analyzing, outputting and predicting, the method comprising monitoring at least two selected input signals, each selected input signal indicating a condition related to a property of the industrial robot system, analyzing any combination of said selected input signals utilizing multi sensor data fusion of the signals, outputting from said analysis a result being detection of condition changes in the robot system, and performing a prediction of a residual lifetime of a specific component of said robot system or the whole robot system at said analyzing of said selected input signals, wherein said prediction is based on said detection of condition changes indicating a condition deterioration in the robot system.
