A modular device is used to inspect a confined space in a machine. The entire inspection coverage area and corresponding status are mapped so that the inspection location and associated data are graphically visualized. An accelerometer mounted on the device serves as a tilt sensor and also provides data about a collision of the device with the space being inspected or defects therein. The accelerometer data in combination with an odometry system determines the axial position of the device. A gyroscope mounted on the device is used to determine the device heading. The locational information is used to generate an inspection map that provides inspection history, logged data and a reference that are useful in scheduling the next inspection. The output of the gyroscopes can be used to provide haptic feedback to the device operator to maintain proper device orientation.

Localization, mapping and haptic feedback for inspection of a confined space in machinery

An inspection system for inspecting an internal component of a machine includes a remote controlled vehicle constructed to fit inside a desired portion of the machine; a controller operative to control an operation of the remote controlled vehicle; a tether coupled to the controller and to the remote controlled vehicle, wherein the tether is operative to transmit control signals from the controller to the remote controlled vehicle; and an imaging device extending from a front portion of the remote controlled vehicle and operative to view the internal component. The imaging device has a flexible articulating tip spaced apart from the front portion of the body.
