The prompt
Using the attached reference image, create a realistic 3D model of the **Autonomous Screed Smoothing Robot (ASSR)**. Preserve the rectangular aluminum chassis, four rugged drive wheels, raised laser receiver mast, ESP32 controller enclosure, battery pack, front ultrasonic sensors, and central horizontal screed blade. Include a stepper motor-driven T8 lead screw with two parallel guide rods for 30–50 mm vertical blade adjustment, plus a small vibration motor. Keep the wheels positioned to minimize marks on freshly smoothed screed. Use realistic engineering proportions, metallic materials, black rubber tires, visible mechanical components, and a clean isometric view. Design it as a compact, modular, low-cost college prototype, approximately 600 × 450 × 350 mm. Avoid futuristic styling and prioritize matching the reference image.
