PURPOSE: To provide a steering system of a self-traveling robot and an automatic steering device in order to make the robot travel and perform its work in a field while detecting accurately its own position.
CONSTITUTION: A self-travelign robot is provided with a traveled distance detection means 3, a traveling azimuth measurement means 4, an absolute position detection means 5, a traveling error measurement means 6, and a control means 7 which controls the traveling of the robot by the input of a course set between a starting point and a target point. In such a constitution, the robot can travel while detecting an error between its traveling azimuth and a check point based on the absolute position information and also can easily recognize its own position in a field even while it is traveling on a set course. Then the robot can perform its work while traveling accurately on the set course.
