The sequence of operations our system performs to measure the mass of all blades within a single tray. The robot first localizes the tray and the slots within it using an ArUco marker. The robot then localizes the blades in the tray using a deep-learning model. Subsequently, the robot grips each blade and measures its mass using the load cell embedded in the gripper. Finally, the system updates the GUI and reports the correct order to install the blades in the aero-engine to the human operator.
