    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 method for wirelessly coupling respective transducers of an automated motion platform and a sub-surface sensor node through a skin of a limited-access structure for the purpose of wireless power and data transfer. Coordinates of an as-designed position of the transducer of the sensor node in a local coordinate system of the limited-access structure are retrieved from a non-transitory tangible computer-readable storage medium. Then coordinates of a target position on an external surface of the skin of the limited-access structure are estimated. The target position is calculated to be aligned with the as-designed position of the transducer of the sensor node. The motion platform is moved under computer control so that the transducer onboard the motion platform moves toward the target position. Movement ceases when the transducer onboard the motion platform is at the target position. Then wave energy is transferred between the aligned transducers.

    Abstract: A ground-based visual-inspection system includes a ground-based visual-inspection apparatus and a control system. The ground-based visual-inspection apparatus includes a mobile base, an actuatable arm coupled to the mobile base, and an effector coupled to the actuatable arm. The actuatable arm is locatable in a three dimensional space. The end effector includes a camera configured to capture images of a structure, such as an aircraft. The control system is configured to determine location information of the camera relative to a reference location and associate the location information with the images.

    Abstract: Systems and methods for tracking the location of a non-destructive inspection (NDI) scanner using images of a target object acquired by the NDI scanner. The system includes a frame, an NDI scanner supported by the frame, a system configured to enable motorized movement of the frame, and a computer system communicatively coupled to receive sensor data from the NDI scanner and track the location of the NDI scanner. The NDI scanner includes a two-dimensional (2-D) array of sensors. Subsurface depth sensor data is repeatedly (recurrently, continually) acquired by and output from the 2-D sensor array while at different locations on a surface of the target object. The resulting 2-D scan image sequence is fed into an image processing and feature point comparison module that is configured to track the location of the scanner relative to the target object using virtual features visible in the acquired scan images.

    Abstract: A system for analysis of gaps between modeled parts of an assembly to be produced is provided. The system generates a three-dimensional (3D) visualization environment of 3D models of a plurality of parts in the assembly and performs an analysis of those of the 3D models within a given proximity to each other to determine gaps therebetween, including any non-acceptable gaps with gap distances that exceed an acceptable gap threshold. The system generates, for a non-acceptable gap, an instruction and automatically implements the instruction to correct the non-acceptable gap and confirms that the non-acceptable gap as corrected does not have a gap distance that exceeds the acceptable gap threshold. The system generates an output of a 3D model of the assembly populated with the 3D models and with the non-acceptable gap as corrected for use in connection with production of the assembly.

    Abstract: An audio instrument includes a component assembly, a pan-tilt mechanism, and one or more processors. The component assembly includes a parabolic reflector, an audio device, and a sensor unit. The audio device is configured to one or more of receive or transmit sound waves via a transducer element disposed within a communication envelope of the parabolic reflector. The sensor unit includes a distance measurement sensor. The pan-tilt mechanism orients the component assembly at independent angular rotations about two orthogonal axes relative to a support platform. The one or more processors are configured to control the pan-tilt mechanism to orient the component assembly such that a central axis of the parabolic reflector is aimed towards a specific three-dimensional location for targeted audio communication between the audio device and a target at the specific three-dimensional location.
