A system for detecting that the motion of an automatically operated work machine is abnormal includes: a target position acquisition unit that acquires target position information about a monitoring target part; an abnormal motion region setting unit that sets an abnormal motion region (Rab) based on the target position information; a current position acquisition unit that acquires a current position of the monitoring target part; and an abnormal motion judgment unit. The abnormal motion region (Rab) is set outside the area occupied by the monitoring target part when the monitoring target part is located at the target position. The abnormal motion judgment unit judges whether or not the current position is within the abnormal motion region (Rab).
