Abstract: An oscillation information calculation device includes: a sensor information obtainer that obtains time series position information on a motor as detected by a position detector, and time series sensor information on a movable part as detected by a sensor attached to the movable part, the movable part being connected to the motor via a joint; and an information calculator that calculates and outputs at least one of oscillation presence/absence information, oscillation frequency information, or oscillation causal information, based on the time series position information and the time series sensor information, the oscillation presence/absence information indicating presence or absence of oscillation of the motor and the movable part, the oscillation frequency information indicating an oscillation frequency of the motor and the movable part, the oscillation causal information indicating a cause of the oscillation of the motor and the movable part.
