In an energy museum, a stationary turbine-blade model rests on two low padded stands. A two-window scanner head on a fixed robot arm remains visibly separated from the blade edge. The technician holds a reader in the left hand while using the console with the other hand. Behind the observation rail, a student holds a route card with both hands. The inspection table carries a curvature template, defect tile, hollow soft sleeve, and port cover, with a jointed lamp at the back and a long tool case on the lower shelf. One broad brake plate marks the nearer caster. Clean futuristic equipment shapes and soft color layers distinguish the two-window scanner from the round inspection lamp.
