Abstract: An inspection system for inspecting a machine includes an inspection vehicle constructed for wireless operation while submersed in a dielectric liquid medium. The inspection vehicle is self-propelled. A controller is operative to direct the activities of the inspection vehicle. A plurality of status interrogation systems is disposed on the inspection vehicle. The status interrogation systems are operative to capture inspection data regarding a plurality of inspection procedures performed on the machine.

Abstract: An inspection device for use in a fluid container having at least an opening includes a housing sized to fit through the opening. The housing has at least two fluid flow channels extending therethrough, each having an inlet and an outlet, and a pump maintained in the housing within each fluid flow channel. The pumps are selectively controlled to maneuver the housing within the fluid container. The inspection device continues with a method of in-situ inspection of a container having at least one opening to receive a fluid, that includes up-loading a virtual model of the container into a computer, inserting the device into the container, generating a position signal by the device and receiving the position signal on a computer. A virtual image of the device in the virtual model of the container is generated to determine an actual position of the device within the container.
