Abstract
The force calculation system of the present invention is provided with: an air blowing unit for blowing air at a predetermined pressure; a flow passage for air blown from air blowing unit; a sensing unit for changing the ease of flow of air that flows through a flow passage by deforming when an external force is given; a storage unit for storing in advance the flow volume-force correspondence information showing the correspondence between the magnitude of the force received by the sensing unit and the flow volume at which air blown from air blowing unit flows through the flow passage; and a processing unit for calculating the magnitude of external force received by the sensing unit, on the basis of: the flow volume of air flowing through the flow passage as measured by a flow volume meter; and the flow volume-force correspondence information stored in the storage unit.
