Abstract

A method and a system for managing one or more industrial robots used by an enterprise over one or more of the phases of the asset lifecycle. Monitored data from the robot(s) is used to determine the occurrence of an event that affects the robot operation. The monitored data is transferred either regularly or upon the occurrence of a robot affecting event. The remote location estimates from the transferred data an optimized maintenance interval for the robot(s) and analyzes that data to provide a prediction of needed maintenance on the robot(s). The remote location can use the transferred monitored data to benchmark different features and functions of the robots for a particular robot or against a robot that performs the same function or can benchmark one of the robots against a robot in another enterprise.

Claims

1. A method for condition monitoring and maintenance of an industrial robot, said method comprising:

monitoring data from said robot during its operation;

determining from said monitored data the occurrence of an event that affects the robot;

transferring to a remote location said monitored data either regularly or upon the occurrence of said robot affecting event;

estimating at said remote location from said transferred monitored data an optimized maintenance interval for the robot; and

analyzing at said remote location said transferred monitored data and providing a prediction of needed maintenance on the robot.

2. The method of claim 1 further comprising:

estimating at said remote location from said transferred monitored data the remaining lifetime of the robot or components of said robot.

3. The method of claim 1 further comprising:

analyzing at said remote location said transferred monitored data to determine if the robot is being used in an optimal way to perform the function that the robot is designed to perform.

4. The method of claim 1 further comprising:

analyzing at said remote location said transferred monitored data and generating an alarm about needed maintenance to be performed on said robot.

5. The method of claim 4 further comprising:

transferring said alarm about needed maintenance to be performed on said robot to a site where said robot is located.

6. A method for condition monitoring and maintenance of a plurality of industrial robots located at one or more different plants, said method comprising:

monitoring data from each of said plurality of robots during their operation;

determining from said monitored data the occurrence of an event that affects one or more of said plurality of robots;

transferring to a remote location said data either regularly or upon the occurrence of one or more said plurality of robots affecting event;

estimating at said remote location from said transferred monitored data an optimized maintenance interval for each of the plurality of robots; and

analyzing at said remote location said transferred monitored data and providing a prediction of needed maintenance on each of the plurality of robots.

7. The method of claim 6 further comprising:

benchmarking at said remote location from said transferred monitored data one of said plurality of robots performing a function against another one of said plurality of industrial robots performing said function.

8. The method of claim 6 further comprises:

benchmarking at said remote location from said transferred monitored data maintenance histories of different one of said plurality of robots in order to estimate the lifetime of different robot families.

9. The method of claim 6 further comprising:

benchmarking at said remote location from said transferred monitored data maintenance histories of different one of said plurality of robots in order to estimate the average number of replaced spare parts.

10. The method of claim 6 further comprising:

benchmarking at said remote location from said transferred monitored data maintenance histories of different one of said plurality of robots in order to estimate the machine state summary of the robot families.

11. The method of claim 7, wherein said robots are located in at least two different production plants.

12. The method of claim 6 wherein said plurality of robots are located at one or more different plants of an enterprise and said method further comprises:

benchmarking at said remote location from said transferred monitored data one or more of said plurality of robots against one or more other robots used by another enterprise.

13. The method of claim 6 further comprising:

analyzing said transferred monitored data for each of said plurality of robots to determine if each of said plurality of robots is being used in the optimal way to perform the function that the robot is designed to perform.

14. A system for condition monitoring and maintenance of an industrial robot, said system comprising:

a computing device at said robot having therein program code usable by said computing device, said program code comprising code configured to;

monitor data from said robot during its operation;

determine from said monitored data the occurrence of an event that affects the robot; and

transfer to a remote location said monitored data either regularly or upon the occurrence of said robot affecting event; and

a computing device at said remote location having therein program code usable by said remote location computing device, said program code comprising code configured to;

estimate at said remote location from said transferred monitored data an optimized maintenance interval for said robot; and

analyze at said remote location said transferred monitored data and provide a prediction of needed maintenance on the robot.

15. The system of claim 14 wherein said program code in said computing device at said remote location further comprises code configured to estimate at said remote location from said transferred monitored data the remaining lifetime of said robot or components of said robot.

16. The system of claim 14 wherein said program code in said computing device at said remote location further comprises code configured to analyze at said remote location said transferred monitored data to determine if said robot is being used in an optimal way to perform the function that the robot is designed to perform.

17. A system for condition monitoring and maintenance of a plurality of industrial robots located at one or more different plants, said system comprising:

a computing device associated with one or more of the plurality of robots having therein program code usable by said computing device, said program code comprising code configured to;

monitor data from said robot during its operation;

determine from said monitored data the occurrence of an event that affects the robot; and

transfer to a remote location said monitored either regularly or upon the occurrence of said robot affecting event; and

a computing device at said remote location having therein program code usable by said remote location computing device, said program code comprising code configured to;

estimate at said remote location from said transferred monitored data an optimized maintenance interval for each of said plurality of robots; and

analyze at said remote location said transferred monitored data and provide a prediction of needed maintenance on each of the plurality of robots.

18. The system of claim 17 wherein said program code in said computing device at said remote location further comprises code configured to benchmark at said remote location from said transferred monitored data one of said plurality of robots performing a function against another one of said plurality of industrial robots performing said function.

19. The system of claim 17 wherein said program code in said computing device at said remote location further comprises code configured to benchmark at said remote location from said transferred monitored data maintenance histories of different ones of said plurality of robots in order to estimate the lifetime of different robot families.

20. The system of claim 17 wherein said program code in said computing device at said remote location further comprises code configured to benchmark at said remote location from said transferred monitored data maintenance histories of different ones of said plurality of robots in order to estimate the average number of replaced spare parts.

21.
