Summary:An anomaly detection system (1) according to an aspect of the present invention is an anomaly detection system (1) for detecting an anomaly in a reduction drive (10), the anomaly detection system (1) including: a sensor (11_1 to 11_3) attached to a housing of the reduction drive (10), the sensor (11_1 to 11_3) being configured to detect vibration on the surface of the housing of the reduction drive (10); a statistical analysis unit (12) configured to perform a statistical analysis on the vibration detected by the sensor (11_1 to 11_3); a frequency analysis unit (14) configured to perform a frequency analysis on the vibration detected by the sensor (11_1 to 11_3); and an anomaly determination unit (17) configured to perform anomaly determination on the reduction drive (10) based on a result of the statistical analysis and a result of the frequency analysis.
