Create a cute and highly detailed dog robot with cracked porcelain robotic parts and a biomechanical interior. The outer shell is broken and chipped, revealing cables, pistons, layered machinery and gold circuitry. The character looks ancient, worn, fragmented and repeatedly repaired. Emphasize robotic anatomy: exposed joints, mechanical neck, visible spine and synthetic muscle layers. Materials include porcelain, brushed and oxidized metal, dark polymers and gold details. Surfaces are rough, imperfect and asymmetrical. No clean sci-fi armor, no smooth surfaces. Style is hyper-realistic, cinematic, dark sci-fi, biomechanical and gritty. Mood is melancholic, fragile yet powerful. High poly, ultra-detailed, PBR materials. Very high detail, maximum wear, minimum cleanliness, high complexity.
