According to news reporting originatin g from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Ch itta, Sachin (Palo Alto, CA, US), Hershberger, David (Menlo Park, CA, US), Pauwe ls, Karl (Redwood City, CA, US), filed on July 7, 2023, was published online on September 17, 2024. The assignee for this patent, patent number 12090656, is Boston Dynamics Inc. (W altham, Massachusetts, United States). Reporters obtained the following quote from the background information supplied by the inventors: "Box-like objects represent a large percentage of objects that need to be picked (i.e., removed from a pallet or holding container) in industr ial, manufacturing, logistics, and commercial environments. Typically, boxlike objects are characterized by at least one substantially planar picking surface. Conventionally, during robotic picking, a picking robot handles known sizes, num bers, and types of boxes arranged in a uniform manner on a structured pallet. Us ing mechanical fixtures, some current systems pre-position a pallet of boxes so that a robot can pick them from known pre-programmed locations. Any deviation fr om this known structure, either in the size of the box, the number of boxes, or the location of boxes results in failure of the system. Unfortunately, computer- vision-based systems often rely on the boxes having clean edges at their boundar ies and cannot accurately determine size and/or position of boxes that have adve rtising, printed characters, printed logos, pictures, color, or any other textur e on them. Such boxes have visual edges on their faces (i.e., edges that do not correspond to an actual physical boundary of the box). Because current computer- vision-based systems cannot distinguish the physical edges between two different boxes from other visual edges on the faces of boxes, these systems tend to misj udge the size and position of the box(es). Problematically, picking and moving t he box where the system has misjudged its size and location may either cause the box to slip from the grasp of the robot or may cause the robot to pick two or m ore boxes where it should have picked only one."
