Heroic Yellow Robot with Cape

Create a clean, high-detail full-body 3D character render of {character_name}, a friendly heroic humanoid robot standing in a confident front-facing pose against a pure black studio background. The robot has a bulky armored mech body made of angular mustard-yellow metal panels with black mechanical joints, subtle scratches, beveled edges, and realistic wear. Its head is a square yellow helmet-like monitor with rounded corners, side circular ear modules, a glossy black screen face, and a cute green LED pixel expression: exactly 2 upside-down U-shaped eyes and 1 smiling curved mouth. Add the teal marking {chest_label} on the upper right chest plate. The robot wears exactly 1 dramatic black cape flowing behind both shoulders, with a teal inner lining and teal trim visible along the edges. Include detailed segmented arms, articulated black fingers, large shoulder rings, piston-like elbows, thick armored thighs, knee plates, heavy boot-like feet, and exposed dark understructure between plates. Use cinematic low-key lighting with warm golden rim light from the upper left, crisp reflections on metal, deep shadows, a subtle floor reflection, and an ultra-clean premium sci-fi toy/film render look. Center the character vertically in a portrait composition, slightly low camera angle, sharp focus, no background props, no extra characters, no text except the chest label.
