A bright, futuristic sci-fi room with clean white-gray tiled floors, soft glowing ambient light, and a digital screen in the background. A silver-haired character in a black tactical suit sits relaxed on the floor. Next to him, a small blue robot (with a single large eye and blue-white accents) floats in the air — the robot performs a gentle, continuous up-and-down floating motion: each rise/fall has a moderate 20-30cm amplitude, slow smooth speed, no sudden jolts. The scene’s lighting subtly shifts (e.g., soft reflections on the floor follow the robot’s movement) to keep the quiet sleek futuristic vibe. Video duration: 10 seconds, smooth frame transitions.
