Publication number: 20180361595Abstract: Systems and methods for automating robotic end effector alignment using real-time data from multiple distance sensors to control relative translational and rotational motion. In accordance with one embodiment, the alignment process involves computation of offset distance and rotational angles to guide a robotic end effector to a desired location relative to a target object. The relative alignment process enables the development of robotic motion path planning applications that minimize on-line and off-line motion path script creation, resulting in an easier-to-use robotic application. A relative alignment process with an independent (off-board) method for target object coordinate system registration can be used. One example implementation uses a finite-state machine configuration to control a holonomic motion robotic platform with rotational end effector used for grid-based scan acquisition for non-destructive inspection.Type: ApplicationFiled: June 14, 2017Publication date: December 20, 2018Applicant: The Boeing CompanyInventors: James J.

Publication number: 20180361571Abstract: Apparatus and methods that can be used to stabilize the distal end of an arm (and an end effector attached thereto) of an automated extended-reach tool-equipped assembly. Stabilization is provided by three or more stabilizers, each comprising a stationary part and a movable part. Each stationary part has a fixed location relative to the end effector; each movable part is translatably coupled to a respective stationary part and comprises a contactor disposed at a distal end of the movable part. When the stabilizers are actuated, the contactors are translated toward and into contact with the surface of the workpiece and then locked in place to stabilize the distal end of the arm and the end effector. During tool operation, the stabilizers reduce oscillation of the end effector (and all structure fixedly coupled thereto).Type: ApplicationFiled: January 24, 2018Publication date: December 20, 2018Applicant: The Boeing CompanyInventors: Gary E.

Patent number: 10145670Abstract: Systems and methods that provide a framework for location tracking of a movable target component or device (e.g., an automated device or a hand-operated device) to accurately cover an area of interest along a specified path or in a specified region. Grid patterns are projected onto a surface of a workpiece or a part. The projected grid lines may be straight or curved. Straight grid lines can be parallel or intersecting. The grid pattern may include a path to be followed. The lines of the projected grid pattern are detected by a grid detection sensor which is mounted onboard the movable target component or device. Information from the grid detection sensor is fed to a location mapping program. The systems and methods also enable navigation for use in automated and autonomous manufacturing and maintenance operations, as well as other tracking-based applications.Type: GrantFiled: January 12, 2016Date of Patent: December 4, 2018Assignee: The Boeing CompanyInventors: Gary E.

Patent number: 10053165Abstract: Systems and methods for automated maintenance of the top and bottom surfaces or skins of an integrally stiffened hollow structure (e.g., a horizontal stabilizer) using surface crawling vehicles. Each system uses dynamically controlled magnetic coupling to couple an external drive tractor to a pair of passive trailers disposed in the interior of the hollow structure on opposite sides of a vertical structural element. The external drive tractor is also coupled to an external maintenance tool, which the tractor pushes or pulls across the surface skin to perform a maintenance function. The systems allow maintenance operations to be performed on both surface skins without turning the hollow structure over. Each system is modular and can be transported to and easily set up in a building or factory.Type: GrantFiled: December 11, 2015Date of Patent: August 21, 2018Assignee: The Boeing CompanyInventors: James J.

Patent number: 9740191Abstract: Systems and methods for calibrating the location of an end effector-carrying apparatus relative to successive workpieces before the start of a production manufacturing operation. The location calibration is performed using a positioning system. These disclosed methodologies allow an operator to program (or teach) the robot motion path once and reuse that path for subsequent structures by using relative location feedback from a measurement system to adjust the position and orientation offset of the robot relative to the workpiece. When each subsequent workpiece comes into the robotic workcell, its location (i.e., position and orientation) relative to the robot may be different than the first workpiece that was used when developing the initial program. The disclosed systems and methods can also be used to compensate for structural differences between workpieces intended to have identical structures.Type: GrantFiled: February 12, 2015Date of Patent: August 22, 2017Assignee: The Boeing CompanyInventors: James J.
