Abstract
A self-traveling robot system capable of being automatically positioned with respect to a workpiece including a robot for work on a continuous object, a truck for moving the robot along the continuous object, a distance detection mechanism mounted to the robot for detecting a distance between the robot and the continuous object, a deviation detecting circuit for comparing the distance as detected by the distance detection mechanism with a predetermined value and detecting a deviation between the distance and the predetermined value, and a travel path correcting mechanism for correcting an advance direction of the truck according to the deviation. A method of positioning the self-traveling robot system with respect to the workpiece is also disclosed, which includes the steps of (a) driving a robot which has stopped at a working position and detecting distances between a swiveling table and two measuring points on the workpiece; (b) calculating a tilt angle (.theta.) of the swiveling table relative to the workpiece and a deflection amount (l) from the swiveling table to a reference travel path on which the robot is to be normally traveled according to data obtained regarding the dist…
