Abstract: An unmanned aerial vehicle (UAV) has a flight-only mode with a motor only rotating propellers and not rotating on-board wheels to configure the UAV to fly away from a surface of a structure, and a crawling-only mode in which the UAV is configured to crawl on the surface due to the motor only rotating the wheels while not rotating the propellers. In the flight-only mode, a clutch disengages a motor from the wheels so that the motor only engages the propellers to fly to lift from the surface. In the crawling-only mode, the clutch disengages the motor from the propellers so that the motor only engages the wheels to move the UAV on the surface.

Abstract: A method and an assembly for determining a volume of a tank. A measuring tape having multiple magnets is attached to a first location of the tank. A first circumference of the tank at the first location of the tank is measured. A value of the first circumference is recorded. Multiple wheels coupled to the measuring tape are rotated. Responsive to rotating the wheels, the measuring tape is moved from the first location to a second location of the tank. A second circumference of the tank at the second location is measured. A value of the second circumference is recorded. Based on the value of the first circumference and the value of the second circumference, the volume of the tank is calculated.

Abstract: An ultrasonic dry coupled wheel probe with radial transducers emit ultrasound in substantially all radial directions relative to a longitudinal axis. The probe does not require normalization and is efficient in directing ultrasound to a surface being inspected. The probe has a wheel composed of rubber or other materials for acoustically dry coupling the transducer to the surface. A first transducer is composed of a piezoelectric material so that the transducer receives an electrical signal, vibrates, and generates and transmits sound, such as ultrasound. Similarly, a second transducer receives sound such as ultrasound, vibrates, and generates a corresponding electrical signal. The transducer arrangement both transmits ultrasound to the surface and receives the reflection of the ultrasound from the surface. An acoustic barrier separates the transmitting component from the receiving component. The transducer has annular electroplates adjacent to the piezoelectric material.

Abstract: A two-wheel compact magnetic crawler vehicle for traversing and inspecting surfaces. The crawler comprises a chassis. Two independently actuated magnetic drive wheels are spaced apart in a lateral direction and mounted to the chassis by a hinged joint enabling each wheel to tilt in response to the surface curvature. A probe wheel is provided at the midpoint between the two drive wheels and laterally in line therewith. A spring-assisted probe carrier passively moves the probe wheel vertically relative to the chassis in response to changes in the surface curvature. Additionally, the vehicle includes a probe angle normalization mechanism comprising spring-loaded, vertically moveable, ball casters positioned symmetrically about the probe wheel. The combined utilization of the probe carrier and the caster carrier passively maintain the probe contacting the surface, the chassis level, and the probe normal to the surface irrespective of changes in the surface curvature with vehicle movement.

Abstract: A method according to the disclosure configures a processor to predict metal loss in a structure for remediation. The method uses a machine learning model, trained based upon historical data, to predict metal loss over locations of a structure at a time of the prediction. The method identifies from among the predicted locations a high-risk location on the structure in which a magnitude of metal loss indicates potential remediation being needed, dispatches a robotic vehicle to the high-risk location on the structure and inspects the high-risk location using the robotic vehicle to confirm whether the magnitude of metal loss at the location requires remediation. In further methods, remediation is performed. In still further methods, a three-dimensional visualization of the structure is generated with an overlay which depicts predicted metal loss over the sections of the structure.
