The Clockwork Automaton.

A humanoid steampunk robot standing in an inventor's workshop, its body assembled from polished brass gears, copper pistons, and glass vacuum tubes glowing amber. The chest cavity is open, revealing an intricate clockwork heart with spinning cogs and a tiny pressure gauge. Its eyes are round magnifying lenses with iris-like apertures. One hand holds a delicate porcelain teacup with mechanical fingers.
