ABSTRACT:
A robot control system which automatically improves the success rate of work performed by a robot even if the worked object is unmeasurable or unobservable by a distance on visual sensor. The control system includes a work judging unit which determines the success rate of work performed at a teaching point of the robot. The control system also includes a search judging unit which judges the result of work at each of a plurality of searching points to determine a success rate of work performed at the searching points. A search instruction unit causes the robot to move to the plurality of search points around the teaching point to perform work or search thereat. A correction unit corrects the teaching point based on the relative relation between the success rate of the work at the teaching point and the success rate at each of the searching points.
