The prompt

"Generate a 3D solid model (STEP file) based on the attached image. Please model the exterior shell only (surface modeling), completely ignoring any internal mechanical components or internal structures. The design is a hard-surface mechanical robot divided into four main sections: 1. Base: A flat, rectangular mobile platform with chamfered corners. There is a dark, box-like utility container mounted on the top rear of this base. 2. Central Column (Waist): A thick, rigid, segmented vertical pillar connecting the mobile base to the upper torso. It features prominent circular joint details on the sides. 3. Upper Torso & Arms: A humanoid upper body with smooth, segmented armor plates. It includes mechanical arms with distinct shoulder, elbow, and wrist joints, terminating in robotic hands with articulated fingers. 4. Head: A smooth, motorcycle helmet-like shape with a flat, horizontal recessed visor area. Style: Clean mechanical design, solid modeling, well-defined sharp edges combined with smooth aerodynamic curves on the upper body. Keep the geometry simple and optimized as an empty outer shell."
