Abstract: A characteristic calculation device includes a sensor information obtainer that obtains position information indicating a position of a motor as detected by a position detector, and acceleration information indicating an acceleration of a movable part connected to the motor as detected by an acceleration sensor attached to the movable part; and a sensor characteristic calculator that calculates and outputs at least one of balance information or detection sensitivity information, based on the position information and the acceleration information, the balance information indicating a degree of matching between a direction of an axis of detection by the acceleration sensor and a direction of acceleration to be detected by the acceleration sensor, the detection sensitivity information indicating a detection sensitivity of the acceleration sensor.
