หุ่นยนต์พิธีชงชาเซน

A serene Japanese tea room rendered as a refined monochrome ink-and-wash illustration on aged parchment, with soft sepia-gray tones, delicate brush textures, and precise hand-drawn linework. On the right side, a humanoid {argument name="robot type" default="service robot"} kneels in seiza on tatami mats, its smooth white shell and exposed mechanical joints depicted with elegant technical detail, gently bowing its head as it pours hot tea from a cast-iron teapot into a small ceramic cup. The robot wears a simple cloth apron tied at the waist, blending traditional tea ceremony etiquette with futuristic machinery. In the center foreground, a low black wooden tea table holds exactly 5 visible tea objects: 1 dark ceramic vase with a thin branch of sparse leaves, 1 bamboo whisk standing upright, 1 tea bowl, 1 small teacup on a round tray, and 1 cast-iron teapot in the robot’s hands. A faint curl of steam rises from the freshly poured tea. Behind the table, a hanging scroll displays a single enso circle painted in expressive brushwork. On the left, tall shoji screens diffuse soft daylight across the room. The walls are plain plaster with subtle wear and ink-like stains, and the overall composition is calm, balanced, minimalist, and contemplative, combining wabi-sabi Japanese aesthetics with quiet science-fiction. Use a wide cinematic composition, eye-level perspective, lots of negative space, and a meditative mood.
