Abstract: An industrial robot having a manipulator and a robot controller configured to control the motions of the manipulator. The robot controller is configured during lead-through programming of the robot to compare a robot position or a robot orientation (TCP) with at least one virtual position or virtual orientation defined in space, and to actively control the motions of the robot in relation to the at least one virtual position or virtual orientation when the difference between the robot position or robot orientation and the least one virtual position or virtual orientation is smaller than an offset value.

Abstract: A method for defining an outline of an object includes the steps of: placing the object on a display; highlighting a non-obstructed pixel on the display; highlighting an obstructed pixel on the display; and capturing a first image of the display. The non-obstructed pixel being visible in the first image and the obstructed pixel not being visible in the first image, which information is used to define at least a part of the outline based on the location of the non-obstructed pixel alone, based on the location of the obstructed pixel alone, or based on the locations of the non-obstructed pixel and the obstructed pixel. The outline definition is thereby based on on/off signals i.e., whether or not individual pixels whose positions on the display are known and are visible, rather than on gradients on an image.
