9. A apparatus for determining the status of a robot, the apparatus comprising:
a data acquisition unit configured to acquire first data and second data related to an operation of the robot; and
a status determination unit configured to acquire 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, acquire 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, generate a Lissajous figure by DQ transforming a three-phase signal based on the second data related to the operation of the robot, acquire a second comparison result by comparing the generated Lissajous figure with a reference Lissajous figure, and determine the status of the robot based on at least one of the first comparison result and the second comparison result.
