Abstract
A force sensor diagnostic device that diagnoses a force sensor provided in a robot, the force sensor disposed near an installation surface on which the robot is installed and detecting a force and a moment applied to the robot from an outside. The device includes a calculation unit that calculates a theoretical value of the force and a theoretical value of the moment detected by the force sensor, a determination unit that determines whether the force sensor is distorted by comparing an actually measured value of the force and an actually measured value of the moment detected by the force sensor with the theoretical values of the force and the moment, and a notification unit that notifies a determination result from the determination unit.
