Abstract
A system which can improve the reliability of an emergency stop operation of a robot when contacting a worker. The system is comprised of a force sensor and a malfunction judgment part. The force sensor has a detection part which detects the load in one direction. The detection part includes a first detection element and a second detection element. The malfunction judgment part judges if a first detection value which is detected by the first detection element and a second detection value which is detected by the second detection element differ from each other. If the first detection value and the second detection value differ from each other, it is judged that the first detection element or second detection element have malfunctioned.
