Abstract: A method for monitoring thermal patterns of a machine includes identifying at least one location for positioning a robotic arm. The robotic arm is equipped with at least one of a visual camera and a thermal imaging camera adapted to capture a visual image and a thermal image of a portion of the machine, respectively. The method includes defining a plurality of segments of the portion by allocating a plurality of grids to the portion. Further, the portion of the machine is scanned by the robotic arm, based on the plurality of grids with the at least one of the visual camera and the thermal imaging camera. A component of the machine is detected, when the thermal patterns recorded for the component deviate from a predefined thermal pattern. The portion of the machine is then rescanned for determining changes in the thermal patterns as a function of time.
