futuristic robot cube 3d model

Futuristic AI avatar, symmetrical floating diamond-shaped mechanical core, four sharp angular metallic segments forming a perfect rhombus around a central circular camera cavity. Dark gunmetal and black metal, hard-surface sci-fi construction, layered mechanical panels, beveled edges, subtle recessed details. In the exact center is a small extremely bright red-white glowing light, no iris, no pupil, no biological eyeball. A single curved mechanical upper eyelid/shutter partially surrounds the central light, designed to rotate and tilt to create expressive emotions. The central glowing light can visually move left and right behind the eyelid like an AI camera. Clean readable geometry, physically plausible separate mechanical parts, perfect symmetry, compact design, realistic PBR metal, high-detail hard-surface 3D model, isolated object, front view, centered, no background, no holographic sphere, no HUD, no text, no platform.
