generate a quadratic picture that shows the following scene: Ultra-realistic, modern industrial construction site inside a partially finished building. A worker wearing a safety helmet and a lightweight wearable robotic exoskeleton with exactly ONE additional robotic arm mounted on the upper back. The person has two completely normal human arms and one robotic third arm. The scene clearly demonstrates a new degree of freedom and human augmentation, not replacement. The robotic arm is firmly holding and precisely positioning a long metal support rail overhead. Both human hands are simultaneously operating a power drill and fastening the rail to the concrete ceiling. The task would be impossible with only two arms because the rail must be held in place while both hands are needed for alignment and fastening. The robotic arm looks intelligent, ergonomic, and integrated into the workflow. It is clearly assisting the worker as a collaborative extra limb. The interaction between human and robotic arm feels natural, practical, and immediately understandable. Clean construction site background with concrete columns, unfinished walls, subtle scaffolding, and construction materials. No city skyline, no skyscrapers, no visual clutter, no distracting machinery. Minimalistic industrial environment with shallow depth of field.
