Abstract
A method for calibrating a robot coordinate system of a robot with a conveyor coordinate system of a movable conveyor member, the method including providing a sensor configured to detect positions of the robot in a non-contact manner; detecting a position of the robot when the conveyor member is positioned at a first operating position; detecting a position of the robot and/or of the conveyor member by the sensor in the sensor coordinate system when the conveyor member is positioned at a second operating position different from the first operating position; and determining a relationship between the robot coordinate system and the conveyor coordinate system based on at least one detected position of the robot in the sensor coordinate system. A robot system and a control system are also provided.
