Title:
ROBOT CONTROL DEVICE, MAINTENANCE MANAGEMENT METHOD, AND MAINTENANCE MANAGEMENT PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/215993
Kind Code:
A1
Abstract:
The present invention accurately evaluates the degree of deterioration of a robot body. A robot control device 300 comprises: a drive control unit 309 that controls the operation of a robot body 200; a detection unit 310 that detects a signal used to analyze a feature value for quantitatively indicating the degree of deterioration of the robot body 200 which deteriorates over time in accordance with the operation of the robot body 200; a determination unit 304 that determines whether a data interval of the signal includes a constant speed interval at or above a fixed interval; a normalization unit 305 that normalizes the signal in a non-constant speed interval when the data interval of the signal does not include a constant speed interval at or above a fixed interval; an analysis unit 307 that analyzes the feature value on the basis of a signal feature value in the constant speed interval when the data interval of the signal includes a constant speed interval at or above a fixed interval, and analyzes the feature value on the basis of the normalized signal in the non-constant speed interval when the data interval of the signal does not include a constant speed interval at or above a fixed interval; and an estimation unit 308 that estimates the remaining service life of the robot body 200 on the basis of the feature value.
