Document Type and Number:
WIPO Patent Application WO/2023/080203
Kind Code:
A1
Abstract:
A current-related basis data acquisition unit acquires first current-related basis data and second current-related basis data pertaining to the current of a motor for driving a robot. A basis temperature acquisition unit acquires a first basis temperature and a second basis temperature that are in effect during the aforementioned acquisition of data. A current-related data acquisition unit acquires current-related data pertaining to the current of the motor. A temperature acquisition unit acquires a data acquisition temperature that is in effect during the aforementioned acquisition of data. On the basis of the first current-related basis data, the second current-related basis data, the first basis temperature, the second basis temperature, and the data acquisition temperature, a correction unit corrects the current-related data so as to correspond to a prescribed evaluation reference temperature. A robot state evaluation unit evaluates the state of the robot using the corrected current-related data.
