    Abstract: A motorized rolling maintenance cart that utilizes the angled trailing edge geometry of an airfoil-shaped body (such as a wind turbine blade or rotor blade) to traverse the length of the airfoil-shaped body. The trailing edge-following maintenance cart may be used to carry personnel doing maintenance activities on the blades, such as local repairs or re-painting. In accordance with one aspect, the maintenance cart carries non-destructive inspection sensor units or other maintenance hardware over the surface of the airfoil-shaped body (e.g., in a spanwise direction). In accordance with another aspect, the trailing edge-following maintenance cart is configured to also provide fall protection to one or more independently movable crawler vehicles by means of cables. Alternative embodiments may include only one of the two aspects.

    Abstract: A tracking-enabled extended-reach tool system acting upon a workpiece. The tool system includes a gimbal positioned adjacent an opening in a surface, a sensor system, a computer control, and a display. The extended-reach arm has a first end, a second end, an end effector including a tool adjacent the first end. The extended-reach arm engages the gimbal for relative rotational movement and relative slidable movement through the opening positioning the end effector and the tool on a side of the surface opposite the second end. The sensor system is configured to measure a linear position of the extended-reach arm relative to the gimbal. The computer control receives signals from the sensor system indicative of the linear position of the extended-reach arm relative to the gimbal. The display is connected to the computer control and displays a representation of the workpiece and the tool relative to each other in real time.

    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: Apparatus and methods for measuring a position of a point on a submerged surface. The apparatus includes: a platform; a liquid-tight pressure vessel fixedly coupled to the platform, wherein the liquid-tight pressure vessel is formed in part by an optically transparent enclosure; a pan-tilt mechanism coupled to the platform and disposed inside the liquid-tight pressure vessel; a camera mounted to the pan-tilt mechanism; a laser range meter affixed to the camera; and a refractive index sensor coupled to and disposed outside the liquid-tight pressure vessel. In accordance with one proposed implementation, the optically transparent enclosure is spherical, the pan-tilt mechanism has a pan axis and a tilt axis that intersect at a center of the optically transparent enclosure, and the laser range meter is located to emit a laser beam that is perpendicular to the optically transparent enclosure.

    Abstract: An automated high-speed method for inspecting metal around fasteners and a computer-controlled apparatus for performing that inspection method. The apparatus comprises a multi-motion inspection head mounted on a scanning bridge, a robotic arm, or a robotic crawler vehicle. The multi-motion inspection head comprises a millimeter waveguide probe and a motorized multi-stage probe placement head that is operable for displacing the waveguide probe along X, Y and Z axes to achieve multiple sequenced motions. The waveguide probe is attached to a mandrel that is rotatably coupled to an X-axis (or Y-axis) stage for rotation about the Z axis. Smart servo or stepper motors with feedback control are used to move the waveguide probe into place and then scan across or around a fastener head to inspect for cracks that may be under paint.
