The ML model can be used to process an image generated by a camera positioned by a robot relative to a target object based on a multi-dimensional representation of the target object. The output of the ML model can indicate, for a detected target, position data, a target type, and/or a visual inspection property. This output can then be used to update the multi-dimensional representation, which is then used to perform robotics operations on the target object.

  • Patent number: 11755811
    Abstract: A method is disclosed for creating a flattened version of a three-dimensional electrical harness assembly design in a computer-aided design environment. The method includes storing data in computer memory including route segment identifiers, diameters, lengths, and end points for route segments in the electrical harness assembly. A computer processor designates route segments as forming a trunk line of the electrical harness assembly, based on the stored data, and produces a flattened two-dimensional version of the design. All the route segments designated as forming the trunk line are represented in the flattened 2D version by straight connected lines, having a particular orientation (e.g., horizontal), and every other route segment is represented as extending out from the trunk line. The flattened 2D version is displayed on a display screen of a computer.

  • Patent number: 11654002
    Abstract: A method for representing a change in a tooth position includes creating a volume data record of an initial position of teeth in a maxilla or mandible and ascertaining teeth boundaries therefrom. A surface data record is created following a real or virtual change in the tooth position. The surface data record includes surface data of the teeth and/or parts of the volume data record of the jaw in an altered tooth position. The surface data record is referenced with the volume data record via a reference structure. The change in the tooth position in the volume data record is transformed to align teeth boundaries with the surface data of corresponding teeth from the surface data record to move tooth structures contained in the volume data record and concealed under a surface. An altered volume record with the change in the tooth position is then outputted for representation purposes.
