  • Publication number: 20190094149
    Abstract: Systems and methods for measuring the distance to a target object and acquiring scale and point-to-point distance information for that target object in an environment using a remotely operated flying platform, such as an unmanned aerial vehicle (UAV). The system uses on-board sensors and processing techniques to provide discrete or continuous measurements of the distances between points on a target object or the scale of the target object. The addition of on-board three-dimensional measurement capabilities to UAVs (or other flying platforms) allows the collection of distance data. Having this capability enables these systems to acquire distances between points on a single object, such as determining the true scale factors of items in images captured by the UAV, in the course of performing metrology-related tasks.

  • Publication number: 20190098221
    Abstract: Systems and methods for measuring the distance to a target object and acquiring three-dimensional coordinates, scale information, and point-to-point distance information for that target object in an environment using a remotely operated cable-suspended platform. The system uses on-board sensors and processing techniques to provide discrete or continuous measurements of the distances between points on a target object or the scale of the target object. The addition of on-board three-dimensional measurement capabilities to cable-suspended platforms enables these systems to acquire three-dimensional position data defined in the coordinate system of the environment, determine distances between objects or between points on the same object. The system can also be used to determine the scale factors of items in images captured by a camera carried by the cable-suspended platform, in the course of performing metrology-related tasks.

  • Publication number: 20180361595
    Abstract: 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.

  • Publication number: 20180361571
    Abstract: 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).
