Abstract

The torque sensor of the present embodiments comprises a first structure to be coupled to an object to be measured, a second structure, a first bridge circuit including a plurality of first strain sensors configured to detect force to be transmitted between the first structure and the second structure, a second bridge circuit including a plurality of second strain sensors configured to detect force to be transmitted between the first structure and the second structure, and a controller configured to output a signal indicating an abnormality when a difference between a first output voltage of the first bridge circuit and a second output voltage of the second bridge circuit is greater than a first threshold voltage.
