Abstract:
A multi-axis tool may include, in some embodiments, a gimbal adapted to be positioned adjacent an opening in a wall; an extended-reach device having first and second ends and an end effector adjacent the first end, the extended-reach device engaging the gimbal for relative rotational movement and relative slidable movement through the opening such that the end effector is positioned on a side of the wall opposite the second end; a sensor system configured to measure a linear position of the extended-reach device relative to the gimbal, and a position and spatial orientation of the end effector relative to the opening; and a computer control connected to receive signals from the sensor system to determine at least one of a position and an orientation of the end effector relative to the opening.
Abstract:
A system for stand-off inspection comprising local positioning system hardware and a nondestructive evaluation instrument supported by a pan-tilt mechanism. The system further comprises a computer system that is programmed to perform the following operations: (a) directing the local positioning system hardware toward an area of a surface on a target object by control of the pan-tilt mechanism; (b) activating the local positioning system hardware to acquire an image; (c) processing the image to determine whether an anomaly is present in the area; (d) if an anomaly is present, determining coordinates of a position of the anomaly in a coordinate system of the target object; and (e) directing the nondestructive evaluation instrument toward a position corresponding to the coordinates. Optionally, the computer system is further programmed to measure one or more characteristics of the anomaly.

Certain aspects of the present disclosure provide techniques for a method, including: receiving multi-dimensional event data associated with a vehicle event; determining, based on the multi-dimensional event data, an inspection classification for the vehicle event; receiving multi-dimensional analysis data associated with the inspection classification for the vehicle event; determining, based on the multi-dimensional analysis data, a repair classification for the vehicle event; receiving multi-dimensional action data associated with the repair classification for the vehicle event; and determining, based on the multi-dimensional action data, a monitoring classification for the vehicle event.
Abstract:
Non-destructive testing apparatuses, systems, and methods for assessing strain in structural components are disclosed. Structural components include induced predetermined regions having materials of varying density, including induced geometric patterns of differing densities within the structural component that can be a composite material structural component. The method includes projecting waves of energy, that can be beams of electromagnetic (EM) energy and/or waves of ultrasonic (UT) energy, into or through the structural component to evaluate the predetermined induced pattern region of varying density and determining existing strain within a structural component based on the detected energy response.
Abstract:
Skinned cell structures and methods of producing the same are disclosed. A disclosed example apparatus includes a placer to place foamable structures together to define a bundle, a restrainer to restrain the bundle, an activator to activate the foamable structures to expand and form a cell structure within the restrainer, a trimmer to trim the cell structure to define a core, and an assembler to couple a skin to the core to define the skinned cell structure.
Abstract:
Systems and methods for tracking the location of a non-destructive inspection (NDI) scanner using scan data converted into images of a target object. Scan images are formed by aggregating successive scan strips acquired using one or two one-dimensional sensor arrays. An image processor constructs and then compares successive partially overlapping scan images that include common features corresponding to respective structural features of the target object. The image processor is further configured to compute a change in location of the NDI scanner relative to a previous location based on the respective positions of those common features in the partially overlapping scan images. This relative physical distance is then added to the previous (old) absolute location estimate to obtain the current (new) absolute location of the NDI scanner.
Abstract:
End effectors and systems may capture, release, and/or create a mating engagement between the end effector and a target object. Said end effectors are tolerant of positional and rotational misalignment of the target object, and include a plurality of roller wheels, one or more of which is arranged in a non-parallel plane with respect to one or more other roller wheels. A first roller wheel configured to rotate in a first plane, a second roller wheel configured to rotate in a second plane, and a third roller wheel configured to rotate in a third plane may be arranged such that the end effector is configured to engage a passive receptacle of the target object, to capture the target object. Rotating the roller wheels in the opposite direction may cause the target object to be released or launched, by urging the passive receptacle off of or away from the roller wheels.
Abstract:
A reinforced sandwich panel, including two skin panels; a foam core disposed between the two skin panels; and an expandable framework disposed within the foam core.
Abstract:
Methods and apparatus for performing repair operations using an unmanned aerial vehicle (UAV). The methods are enabled by equipping the UAV with tools for rapidly repairing a large structure or object (e.g., an aircraft or a wind turbine blade) that is not easily accessible to maintenance personnel. A plurality of tools are available for robotic selection and placement at the repair site. The tools are designed to perform respective repair operations in sequence in accordance with a specified repair plan, which plan may take into account the results of a previously performed UAV-enabled inspection.
Abstract:
Systems, apparatus, and methods for musculoskeletal ergonomic improvement are disclosed. An example apparatus includes a performance analyzer to predict a musculoskeletal strain event for a portion of a body of a user based on strain sensor data collected via one or more strain sensors associated with the user and transmit, in response to the prediction of the strain event, an instruction including an alert to be output by the output device. The example apparatus includes an ergonomic form recommendation generator to transmit, in response to the prediction of the strain event, an instruction including an ergonomic form measure to be output by the output device.
