Abstract: An apparatus and method for calibrating or teaching a robot, the apparatus includes a reflective photoelectric sensor arranged on a gripper of the robot and a controller. The controller is configured to: cause the reflective photoelectric sensor to scan over a target object; monitor changes in an output signal from the reflective photoelectric sensor; for each detected change exceeding a threshold, determine a coordinate of a gripping component on the gripper in a robot coordinate system, to obtain a set of coordinates; determine a position of the target object in the robot coordinate system based on the set of coordinates and a predefined offset value (PO) between the reflective photoelectric sensor and the gripping component; and store the position of target object for future use in assembling objects.

Abstract: An apparatus for detecting tilt of a fixture and method thereof. The apparatus includes a visible element having a pattern visibly distinguishable from its surrounding area; a part having a plane reflective surface being configured to be engaged with the fixture in alignment and being arranged to reflect light beams propagating directly from the visible element so as to produce a first virtual image of the visible element; an image capture device being disposed at same side of the visible element with respective to the part having a plane reflective surface and being configured to have a field of view covering the first virtual image and a second virtual image of the visible element produced by the part having a plane reflective surface, wherein the second virtual image was produced where the part having a plane reflective surface assumed a levelling orientation; and a controller being adapted for detecting tilt of the fixture using a deviation of the first virtual image from the second virtual image of the visible element in the field of view of the image capture device. By using the apparatus or method according to present invention, no optical means, such as lens, is used for converging the light beams projected by the visible element. It is thus possible to facilitate the assembly of the apparatus, miniaturize the apparatus and reduce costs thereof.
