  • Localization, mapping and haptic feedback for inspection of a confined space in machinery
    Patent number: 10712391
    Abstract: 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.
