Abstract
A method for calibrating a robot system having a planar pick surface includes: bringing a robot gripper to a first location against the pick surface; and generating a first image of the robot gripper from below. When knowing that a certain identifiable part of the robot gripper in images always lies against the planar pick surface, the position and orientation of the pick surface in relation to a manipulator coordinate frame can be fully defined if the robot gripper's orientation in relation to the pick surface is known, or if there are images on identifiable parts of the robot gripper in at least three different positions against the pick surface.
