Abstract: A state estimation device is provided, which includes: a machine controlling unit for controlling a work machine based on a sensor value acquired from a sensor configured to output the sensor value related to an operation by the work machine; and a state estimation unit for estimating a state of the sensor based on the sensor value. In addition, a system is provided, which includes: the state estimation device; the work machine; and the sensor. In addition, a method of manufacturing a manufacture item by a work machine is provided, which includes: controlling the work machine based on a sensor value acquired from a sensor configured to output a sensor value related to an operation by the work machine on the manufacture item; and estimating a state of the sensor based on the sensor value.
