    Abstract: Examples disclosed herein relate to creating a surface identifier using a shape memory material. In one implementation, a processor determines a first property value of the surface identifier associated with a first phase and a second property value of the surface identifier associated with a second phase. A manufacturing device may create a surface identifier using a shape memory material. In one implementation, the surface identifier is created in a manner that causes the surface identifier to exhibit the first property value when the shape memory material is in a first phase and to exhibit the second property value when the shape memory material is in a second phase

    Abstract: A method comprises moving a robotic structure to a first pose such that an end-effector of the robotic structure has an absolute position comprising an absolute location and absolute orientation. The method comprises providing a calibration artefact on the end-effector. The method comprises determining at least three planes coinciding with at least three respective surface planes of the calibration artefact, by measuring absolute locations of a plurality of points on the calibration artefact. The method comprises determining the absolute location and absolute orientation of the end-effector, when the robotic structure is in the position based on the determined at least three planes. The method also comprises calibrating the first pose of the robotic structure using the determined absolute location and absolute orientation of the end-effector.

    Abstract: An example system includes a feature extraction engine. The feature extraction engine is to determine a plurality of scale-dependent features for a portion of a target. The system also includes a signature-generation engine to select a subset of the plurality of scale-dependent features based on a strength of each feature. The signature-generation engine also is to store a numeric representation of the portion of the target and the subset of the plurality of scale-dependent features.
