Abstract
In 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, white light emitted by a white LED is transmitted through the lubricating oil, causing an RGB sensor to detect the color of the light transmitted through the lubricating oil by the white LED. The brightness of the color detected by the RGB sensor is calculated. 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 is calculated. The states on the basis of the calculated brightness and the calculated color component maximum difference are determined.
