Abrégé
A state determination method is provided that is capable of determining at least one of the state of degradation of oil in a machine and the state of breakage of the machine with higher accuracy than conventional methods. A state determination method for determining the state of degradation of lubricating oil in a speed reducer and the state of breakage of the speed reducer is characterized by: transmitting white light emitted by a white LED through the lubricating oil, causing an RGB sensor to detect the color of the light transmitted through the lubricating oil by the white LED, and calculating the brightness of the color detected by the RGB sensor (S201); calculating a color component maximum difference that is the difference between a maximum value and a minimum value among the R value, G value, and B value of the color detected by the RGB sensor (S202); and determining the states on the basis of the brightness calculated in S201 and the color component maximum difference calculated in S202 (S203, S207).
