A novel robotic system integrating thermal history instrumentation with an industrial-grade robot is currently being developed by SCS. The system is envisioned to perform autonomous thermal measurements on engine components of different shapes and sizes. The objective of this work is to develop an algorithm for the validation and the optimization of the achievable signal. The acquired signal is investigated through different alignments and clearances between the robot's tool and the measurement spot. The measurement's quality is related to characteristic parameters of the signal. Results of the analysis are used to develop the main algorithm. Communication lines, between the robot and the thermal history instrumentation, are exploited for the transmission of a valid flag, useful to the robot to decide whenever to undertake the optimization process.
