Hero prompt: Create a premium industrial mascot character for a crawler undercarriage and construction machinery chassis company.

Create a premium industrial mascot character for a crawler undercarriage and construction machinery chassis company. The mascot is a friendly but professional engineering robot, with a realistic crawler track undercarriage as its lower body. It should have a clear character identity, not just a vehicle. The upper body should be a compact robot torso with a simple helmet-like head and a digital visor face, small friendly LED eyes, and no human baby face. The lower body should look like a real heavy-duty crawler undercarriage, stable and strong. Use industrial yellow, dark gray, and black colors. The design should feel reliable, stable, professional, and suitable for an international B2B machinery brand. Add clean blank areas on the helmet and chest panel for placing a company logo later. Do not generate any text, logo, letters, symbols, or watermark. Full body, front three-quarter view, clean white background, studio lighting, high-quality 3D render, product catalog style.
