Abstract
A method for determining the status of a robot according to an embodiment includes acquiring first data and second data related to an operation of the robot, acquiring a resonance frequency by analyzing the operation of the robot in a frequency region based on the first data related to the operation of the robot, acquiring a first comparison result by comparing the acquired resonance frequency with a reference resonance frequency, when the first comparison result is a threshold value or more, generating a Lissajous figure by DQ transforming a three-phase signal based on the second data related to the operation of the robot, acquiring a second comparison result by comparing the generated Lissajous figure with a reference Lissajous figure, and determining the status of the robot based on at least one of the first comparison result and the second comparison result.
